Introduction:

VArKON series reactive power controllers have been developed to

solve the power factor correction problems by suitable models for

different kind of power systems.

That controller can be started up and easy commissioning on any

kind of power factor compensation system for controlling and energy

analysis with their reach and real user friendly menu.

When first starting up the compensation system with VArKON

controllers;

- It is very easy to define the stage power according power

analysis on the system’s reactive power requirements and

gives some suggestions with reactive and active power rates.

Thus shows; necessary capacitive and/or inductive reactive

powers to connect for several steps as guidance.

- Corrects the connection errors, learns and detects

continuously the step powers, records the important events

on real time.

- Works smartly leading and lagging side in order to reach to

the requested target in intelligent timing, thus lets the

minimizing the operations and maximizing the life of the

system.

- All models meet the capacitors and reactors, but model TCR

makes inductive adjustments sensitively and let the single

phase requirements to be minimized.

The controllers which can be used

successfully with the contactors are

suitable some facilities as below:

Industrial facilities with 3-phase

Factory plants

Petrol stations

Markets

Banks

Schools

Buildings

Housing estate

Most necessary information on the

main display

-Monthly-weekly-daily-hourly rates

-Real-time clock

-Reach analyzing parameters

-Sensitive measuring as 5mA

-Measuring up to 63th harmonics

-Accuracy as 0.2%

What is the suggests about daily

requirements on the steps?

No need further power analyzing!

For example according display as above:

At first line – If you add 5kVAr 3ph unit

Inductive rate will be reduced 6.2%.

At fourth line – If you connect; 1kVAr

reactor to L3 phase, capacitive rate will

be reduced 0.7%

What is the position of the steps?

You can switching cycles and connection

time for all of the steps in one display.

Communication:

VArKON power factor controllers are equipped with

a RS485 communication port as optional or

standard. The Modbus RTU protocols are available

through the RS485 in order to interconnect the

VArKON or PLC systems. All parameters can be

followed or relay adjustments and/or commands

could be set/reset.

Easy to reach for all parameters and set/reset possibility by means of internet connection with free VArKON NET and VArKON COM soft
