Electrical system concernsl ENERGY EFFICIENCY
However, when surge suppressors and isolation transformersare coupled with a voltage regulator, like Staco’s PLC, thecombination can provide an excellent solution to these powerquality problems.

l ELECTRICAL NOISE
There are four main types of regulators offered in today’smarket . . . Ferroresonant , Tap Switching, Limited RangeVariable Transformer, and Variable Transformer Buck-Boost.
l BROWNOUTS FERRORESONANT
In today’s world, the cost of electrical power and its qualityhave become major operating concerns. The continuingincrease in the cost of electrical power has heighten interest inenergy savings and poor power quality has been indentifiedas a cause of malfunctions and expensive shutdowns in newhigh technology equipment.The chart below shows some of the causes and the effects ofpoor power quality. Filter networks, surge suppressors, andisolation transformers can solve many of the power qualityproblems that occur, but each can involve system tradeoffs ifapplied as a stand alone solution. Filter networks tend to betuned to an existing load condition and if the load changes theengineered network may become ineffective. Surge suppres-sors shunt voltage transients to ground possibly transforming aline voltage problem into a ground potential problem. Shieldedisolation transformers can provide electrical noise attenuation,but like filters and suppressors do not offer protection againstvoltage fluctuations and brownouts.
Ferroresonant constant voltage transformers use a capacitor inseries with the transformer coil and tend to be high impedancedevices that are sensitive to load changes and do not handlehigh inrush loads very well. They can interact with switch modepower supplies to produce transients and electrical noise onthe output and their resonant circuits make them particularlysensitive to frequency changes. When applied cautiously theseunits can provide 2 to 5% output regulation, load isolation,and noise attenuation.
TAP SWITCHING TRANSFORMER
Tap switching transformer based regulators monitor outputvoltage and then use solid-state switching circuits for changingthe transformer taps on a fixed ratio transformer. These unitstend to provide only 3 to 5% output regulation as the numberof taps used are minimized to control cost. Although these reg-ulators are extremely fast, this fast response time can oftencreate instability when powering equipment with switch modepower supplies and their output waveform tends to produceharmonics and radio frequency interference.

LIMITED RANGE VARIABLE TRANSFORMER
Limited range variable transformer regulators use variabletransformers to directly control the output voltage of the regula-tor. This places the variable transformer’s vulnerable brush andbrush track directly in the power path of the regulator subject-ing these critical components to system stresses which canlead to possible premature regulator failure. Applications withhigh overload cycling might require the unit to be oversizedand with the variable transformer brushes in the power path,electrical noise can be introduced into the system. While limit-ed range variable transformer regulators can provide *l to3% output voltage regulation they tend to be larger than theVariable Transformer Buck-Boost Regulator as manufacturedby Staco that offer +l% output regulation.
STACO BUCK-BOOST VOLTAGE REGULATORS
SINGLE PHASE REGULATORS
Staco voltage regulators consist of three basic components: amotorized variable transformer, a buck-boost transformer, anda controller.
Figure 1. Single Phase Regulator Block Diagram
Input power is applied across the motor driven variable trans-former which has a “center tap” that divides the variable trans-former into bucking and boosting voltage areas.
The buck-boost transformer is a fixed ratio isolation transformercapable of high amperes at low voltage. The ratio of the buck-boost transformer is determined by the amount of voltage need-ed to buck or boost the input line voltage to maintain thespecified output level. The buck-boost transformer secondary iswired in series with the load and the primary is connected acrossthe variable transformer’s “center tap” and brush terminals.Depending on which side of the “center tap” the variable trans-former brush is positioned, the variable/buck-boost transformersystem will add to (boost) or subtract from (buck) the input linevoltage. The further the variable transformer brush is from the“center tap” the more bucking or boosting of voltage will occur.
The key to the proven reliability and long trouble free servicelife of a Staco Voltage Regulator is in the combination of amotor driven variable transformer with buck-boost transformertechnology.
As shown in figure 1, the only active component in the mainpower path of the voltage regulator is the secondary of thebuck-boost transformer. This gives the Staco regulator theadvantage of being able to withstand substantial current over-loads. The variable transformer brushes, which are the mostvulnerable component in any variable transformer system, arecompletely isolated from overload conditions by the buck-boosttransformer. Due to transformer inefficiency above rateddesign, the amount of current that the buck-boost transformercan induce across to its primary winding and into the variabletransformer circuit is dramatically decreased as regulator over-load current increases.
The controller monitors the regulator’s output voltage and thenuses these feedback signals to determine drive commands forthe variable transformer motor interface circuit. The controlleris designed to adjust the motorized variable transformer toprovide a 21% or better output voltage regulation over theentire input voltage range.
Staco offers two types of controllers. The solid state type LRCcontroller is standard on type AVR regulators and the micro-processor type MP controller which is offered as standard onall MVR voltage regulators and is available as an option forAVR units.

THREE PHASE REGULATORS
Figure 3 illustrates a block diagram for a three phase voltageregulator. There are still only three basic components, but in a
STACO CONTROLLERSTHE LRC CONTROLLER
The type LRC controller is the standard controller for both singleci-l
.three phase configuration, each phase has its own variable Itransformer and buck-boost transformer. The three variable and three phase single line control (SLC) voltage regulators,
transformers are driven by a single motor in what is called asingle line control (SLC) configuration.
In figure 3, one phase of the regulator is selected to representthe control feedback for all three phases. The variable trans-former in each phase is driven by the single motor and thusthe variable transformer brushes in each unit will move by thesame amount, in the same direction, and at the same time.
Staco also offers an individual phase control (IPC) voltage reg-ulator design. In an individual phase controlled unit each out-put phase has its own controller monitored voltage feedbackloop, each variable transformer is driven by its own motor, andeach output phase is regulated independently of the otherphases. Single line control is the design choice for singlephase regulators and in three phase regulators for balancedload applications. An individual phase controlled regulator is anexcellent design choice for three phase distributed load appli-cations, consisting of both single and three phase loads, as theregulator will provide a regulated and balanced output voltageeven under unbalanced line and load conditions.
Complete schematic diagrams covering single and threephase single line controlled and three phase individual phasedcontrolled units may be found on page 9.
The LRC, limited range controller, utilizes discrete componentsfor feedback voltage monitoring and motor control. The controlleruses a half-wave peak detection and conditioning circuit for ACfeedback monitoring and an optically isolated triac for 120 voltmotor control. The output voltage setpoint is entered through thefront panel potentiometer.The resultant signal is compared to thefeedback signal to determine drive commands for the motorinterface circuit. A second potentiometer on the front panel pro-vides for system deadband and sensitivity control.
THE MP MICROPROCESSOR CONTROLLERThe type MP, microprocessor controller, offers users new flexi.bility in the control of the regulated output voltage.
This intelligent microprocessor based controller is capable oloperating in several different modes which can be programmedlocally with the panel mounted microterminal or remotelythrough a RS-232, B-422, or IEEE-488 bi-directional communi-cation port. The panel mounted microterminal has a LCD displayfor display of output voltages and setpoints. Multiple set pointsmay be programmed for variable speed, ramping, and variabledwell. The AC feedback signal may be configured to be compati-ble to the output voltage. It can be user programmed to acceptpeak to peak, average, or RMS measurements. The MP con-troller is standard on all three phase individual phase controlled(IPC) MVR regulators and is available as an option on all singleand three phase AVR regulators,

WHY CHOOSE A STACO REGULATOR or POWERCONDITIONER...The STACO-PLUSStaco has been in the AC voltage control and regulation fieldsince 1937. Today, Staco’s products reflect this experience.Staco regulators are built for long-term reliability and troublefree operation. High quality components, optimum design, andexcellent workmanship go together to ensure many years ofsatisfactory performance.Conservative Ratings
Staco regulators are designed to withstand substantial currentoverloads.
Accuracy
Staco regulators will maintain a constant output voltage within+l% or better, regardless of input voltage variations from+lO% to - 20% of the nominal input value in standard models.If the supply voltage varies beyond the regulating range, theregulator continues to provide its maximum correction so thatthe output voltage varies only by the amount that the line volt-age deviates beyond the regulating limits. The usefulness ofthis feature is best illustrated by a motor load which can oper-ate satisfactorily on a supply voltage of 20% below nominal;using a Staco regulator, the same motor can be operatedwhen the line voltage falls to 39% below nominal.
No Waveform Distortion- No Harmonics Added
Staco regulators, unlike some types of regulators, cause nowaveform distortion and add no harmonics to the system. Theydo not introduce awkward and irritating errors in voltage andcurrent measurement which may occur if the normal waveshape of the supply voltage is distorted.
Independent of Power Factor
Staco regulators perform equally well whether the connectedload is capacitive, resistive, or inductive in nature.
Insensitive to Frequency Changes
Staco manufactures regulators which will accept line frequencychanges of up to -10% without loss of output regulation.

Compensates for Load Changes
Staco regulators maintain a constant output voltage regardlessof load current changes from zero to full rated load.
Rated per Industry Standards
Staco regulators are designed and rated to meet standardindustry kVA ratings for application ease in both new and exist-ing installations. No longer is there a need to oversize the reg-ulator to be able to utilize the full capability of a feeder circuit.

SELECTING STACO VOLTAGE REGULATORS andPOWER CONDITIONERSSelecting the Staco Voltage Regulator or Power Conditionerbest suited to your specific requirements is easy once youmake the following determinations:
VOLTAGE REGULATOR OR POWERCONDITIONER
The first step in the product selection process is to determinewhat type of product is required. A voltage regulator isdesigned to take the system input voltage and provide a regu-lated output voltage. The main difference between a regulatorand a power conditioner is that a power conditioner also con-tains a transient voltage suppression package plus an outputisolation transformer. A power conditioner provides output reg-ulation plus load isolation and electrical noise attenuation. Ifsystem brownouts are the major concern, select a VoltageRegulator. If electrical noise, as well as brownouts, are themajor application concern or if load isolation or system voltagestep-down is required, choose a Power Conditioner. VoltageRegulator selection tables start on page 12 and the PowerConditioner selection tables start on page 16.
SINGLE OR THREE PHASE
The second step IS to determine the type of load to be sup-plied. If the load IS a single phase load, choose a single phaseRegulator or Power Conditioner. If the load is three phase or IS
a combination of single and three phase loads, select a threephase unit. Product selection tables start with single phaseunits followed by three phase units.
VOLTAGE
The third step is to determine the selected unit’s voltage rating.There are only a few different nominal system voltages usedthroughout the world. The basic product selection tables, start-ing on page 12, have been designed to meet 95% of the day-to-day needs. Staco Voltage Regulators, unlike some of theother regulator technologies. are designed with an adjustableoutput voltage setpoint. The charts below show standard out-put voltage setpoints available with the standard regulators list-ed in the selectron tables. Using this output setpoint feature, 11basic regulator voltage families can provide a *lob, or better,output regulation for 36 different world system voltages.

Three phase system voltages are either Delta or Wye depend-ing on whether a system neutral is available. A Delta systemhas only three conductors or wires. A Wye system has threeconductors plus a system neutral. A Delta system is known asa three phase, three wire system, where the Wye system isknown as a three phase, four wire system where the fourthwire is the system neutral. The type of three phase supply sys-tern must be determined for proper Voltage Regulator or PowerConditioner application. Staco offers both Delta and Wye threephase units as standard catalog items. Special voltage unitsare available, contact the factory for product information.Domestic units are 60 Hz rated and international units are50/60 Hz rated.
SIZE
The fourth step in the selection process is to determine theunit’s kVA rating. The product selection tables list both theunit’s kVA rating and maximum output amperes. Knowingeither the load kVA or amperes, select a unit that meets orexceeds the load requirements. The kVA ratings listed in theselection tables are based on a unit’s maximum output ampererating at its listed output voltage. If a Voltage Regulator is beingselected based on the output set-point feature, the regulatorshould be selected based on the maximum output ampereswhich remain constant over the unit’s output voltage setpointrange The output kVA will then need to be recalculated basedon the output voltage setpoint and the unit’s maximum outputa m p e r e s . .
As a final step review the application to determine if anyoptions are required.

Staco AVR voltage regulators are enclosed in an indoor ventilated enclosure designed toprovide 100% front accessibility and to fit through a standard thirty inch wide door. All unitsare kVA rated per industry standards and for added application flexibility the output voltageregulation setpoint is adjustable. A brief discussion of the output setpoint feature along withsingle and three phase setpoint charts are covered in the voltage selection section on page10. Staco voltage regulators are designed to provide *l%, or better, output voltage regula-tion over the full input voltage range without any wave form distortion and without any har-monics added to the electrical system. Modular construction with 100% front accessibilitymakes Staco voltage regulators easy to install. By using a low impedance design, the typi-cal Staco voltage regulator provides regulated output at 99% efficiency.

The modular voltage regulator provides the basic building block for the type SLC, PLC, andMLC power conditioners. A power conditioner consists of a voltage regulator with the addi-tion of an output isolation transformer and a transient voltage suppression package. Inaddition to providing il?lb. or better, output regulation without any wave form distortion orharmonics added, Staco power conditioners also provide electrical isolation and noiseattenuation plus voltage suppression. The standard output isolation transformer is of a spe-cial design to provide 120 dB common mode and 60 dB transverse mode noise attenuationwith the voltage suppression package rated for C3 system exposure level. Single phasepower conditioners listed below, 240 volts and above, are designed to provide either 2 wireor 3 wire output. Standard three phase units are designed for a 3 wire Delta input with a 4wire Wye output, and all individual phase controlled units are type MP microprocessor con-trolled. For three phase Wye-Wye units as well as other single or three phase ratings, con-tact the ISE for dimensions and specifications.
Note: SLC units are 50/60 Hz rated 16
