In today’s industrial and business environments, reliable and continuous power supply is critically fundamental to ensure financial or business losses are not incurred. Modern buildings and industrial complexes have critical loads such as essential lighting, computers and constantly operating industrial equipment and therfore continuity of power is vital for these functions.

NHP’s range of circuit breaker and change over switch technology, Automatic Transfer Switches (ATS), are reliable, durable and versatile to suit any application that requires transferring essential loads and electrical distribution systems from one power source to another.

Our ATS units are available with and without a controller. The controllers provide the intelligence to sense the appropriate conditions for the ATS to initiate a transfer and retransfer to ensure a reliable power supply.

Locally stocked and technically supported within Australia and New Zealand, NHP have both off the shelf and customised ATS solutions to meet almost any technical and cost requirement.

Introduction to automatic transfer switches (ATS)

Main types of NHP transfer switches

• Circuit breaker based

- MCCB

- ACB

• Load break switch based

The NHP ATL 610 controller is designed to control and supervise the automatic or manual transfer of the primary power supply to the secondary power supply in the event of a main source interruption. The functional process allows the device to supervise and manage the changeover between two power supply sources and to control the relative transfer equipment your application requires.

The automatic transfer takes place whenever predefined conditions by the user takes place, such as power supply instability, fluctuations (voltage or frequency), or the need to use the most economical power source.

The ATL610 automatic transfer switch controller from NHP is easy to use, expandable and provides reliable transfer switch control for secure supply of power to your facility. The voltage and frequency measurements are shown on the graphic LCD display with a white backlight ensuring readability. In addition, the LED display provides a clear indication about the network status, along with an easy and intuitive menu navigation.

USB and Wi-Fi Dongle

By using the front optical port, direct connection to a PC USB port (using ATLCX01) or via Wi-Fi (using ATLCX02) is allowed. The ATLCX02 Wi-Fi dongle can also make:

• A Copy of the parameters. All parameters in the ATL610 can be saved in the ATLCX02 memory and if required, loaded on the same device (backup function) or on a different ATL610 (replication of the configuration)

• Clone of the device settings. The current values of the statistical data allow for counters and events to be saved in the memory, in order to fully replicate an ATL610 on another device of the same type or to restore the device to a previously saved state

Optical Port

The ATL610 is equipped with a front optical port to support programming through the ATLCX01 dongle and the ATLCX02 Wi-Fi dongle. Advantages are:

• No need to remove power from the ATL610 when inserting or withdrawing the dongle.

• Electrical safety - no external electrical connection when using the dongle.

• IP54 rated socket, with and without the dongle inserted.

• The dongle plugs into the front facia of the ATL610 for convenient access.

Expandability for ATL610 (2 slots)

The configuration of devices in different installations can have many variants, for example, the type of communication (USB, RS485, and Ethernet) or the number of inputs and outputs required. The ATL610 supports expandability via the use of the various “ATLEXP_ _ _ _ “ modules, which are recognised automatically by the ATL610 when installed. The following types of EXP (expansion) modules areavailable:

• Digital inputs and outputs

• USB, RS232, RS485, Ethernet and Profibus communication

Simultaneous AC and DC power supply to an ATL610

The ATL610 offers flexible power supply solutions for easy implementation into most applications, by the use AC and DC auxiliary power supplies simultaneously. An explanation for this, is that during normal mains operation, the ATL610 is supplied by the available AC voltage mains source. If an optional external 12V or 24VDC battery is installed, during a transfer when the mains AC voltage is lost, the ATL610 controller will automatically use the external battery DC supply. When the generator, or source 2 is being used, the controller switches to use the new AC voltage source. Note; an external battery supply differs to ATL610 internal time clock back-up, in which an internal capacitor provides 5 mins of backup during a total loss of supply, where no back up battery is installed.

Graphic LCD Display and Text in 5 Languages

The backlit display with a resolution of 128 x 80 LCD pixels makes the user’s interface easier with benefits during bad light conditions.

The new interface allows the user to clearly see:

• System status

• Voltage and frequency measurements

• Statistical data

Maintenance Counters

The ATL610 includes two counters which are used for maintenance purposes; the first one used to monitor the working hours and the second to count the number of breaker operations. When the counters reach the set limits, the relative alarms trip.

Inputs, Outputs, Internal Variables, Counters

The NHP ATL has 6 inputs and 7 outputs on-board. The input and output functions are preconfigured with the most common settings but the user can easily change the default configuration to adapt the controllers to the application needs. The configurable I/O limits and counters can be enabled and set by accessing the sub menus on the display screen.

There are four types of programmable internal variables:

• 4 limit thresholds

• 16 remote controlled variables

Statistics and Events

The controllers record statistical data which becomes available for the user to understand how the system works. An internal cyclic memory records up to 100 events that provides useful information about the history and the performance of the system controlled.

Real Time Clock for ATL610

The ATL610 has a real time clock with integrated backup battery so all events are identified by the time stamp at which they occurred.

Technical features

• Control thresholds

• Pop-up windows for alarms

• Active inputs and outputs

• 4 user alarms

• 4 programmable counters
