Our Premium Automatic Transfer Switches are the ideal solution for transferring power from the Mains to a Standby supply or from Network to Network supplies. With Mains and Standby three phase monitoring plus full electrical and mechanical interlocking you can be confident of switching supply under fault conditions at any time. With sizes from 63 Amps up to 800 Amps in this range and up to 3200 Amp in our other ranges, we can cover the requirements of all your likely projects.
With full conformity to the latest IEC 60947-6-1 you can confidently specify our range of Automatic Transfer Switches.
Designed for Healthcare buildings Generator manufacturers Fire pump installations Life safety schemes Data centres Features Multiple programable parameters including mains delay timers, changover timers, configurable alarm outputs Locked Rotor Current selection Switching between Line to line, line to generator or generator to generator.
Specifications IEC 60947-6-1 - ATS IEC 60947-1 TB 210: EN 12845 2015:1 EMC Dir. 2004/108/CE EN 61010-1 EN 61000-6-2 EN 61000-6-4
ATS Operation modes & features:
Start / Stop Generator Signal A volt free changeover contact for clients use to signal the Generator to start & stop as required by the control program. A changeover contact is provided with 1 n/o & 1 n/c contact to be used as required by the generator control panel. Delay On Start Timer (DOST) A 'Delay on Supply off' timer is provided and associated with the Generator Start / Stop signal This is adjustable from 0 -60 Seconds and provides a timed delay on the start signal. Delay On Changeover Timer This timer allows a delay to be set in changing over between the Line 1 (MC) and the Line 2 (GC) supplies / contactors. Generator Cool Down Timer Upon a return to the primary Line 1 supply this timer allows the Line 2 supply, if using a Generator to run on for a time period prior to removing the start signal. BMS / Indication Contact - Load On Line 1 A volt free indication contact of the MC Line 1 contactor, This is a N/O contact so when the contactor is open and the Line 1 supply is not on load it is open and when the contactor is closed and on load the contact is closed. Wired to terminals for BMS / Indication Contact - Load On Line 2 A volt free indication contact of the GC Line 2 contactor, This is a N/O contact so when the contactor is open and the Line 2 supply is not on load it is open and when the contactor is closed and on load the contact is closed. Wired to terminals. Test Switch A Key switch is provided to simulate a mains failure, In the Normal position the system is set for Automatic mains failure detection & normal changeover, In the Test position the loss of Supply 1 is simulated and the system will changeover to the standby Line 2 supply. The key is removable in both positions. BMS / Indication Contact - Test Switch A volt free indication contact of the mains fail test switch is given, this is a N/C Contact so when the switch is turned to Test the contact will open and when the switch is turned to Normal the contact will close.
ATS Operation modes OFF mode (OFF) In this mode the device is disabled, and does not take any action. All views, both of the measures of the status LEDs remain active. If the control of the switching devices is impulsive, in OFF mode both open and close commands are disabled. Pressing the OFF- RESET button resets the retentive alarms, provided that the conditions that generated the alarm has been removed. MANUAL mode (MAN) In MAN mode, you can manually control the switches on the display by selecting the switch that you want to control by pressing the MAN key, and pressing the or button to confirm the operation of closing or opening. While the opening-closing of the contactors is enabled, the page scroll is locked. Pressing MAN several times it is possible to unlock it and to move through other display pages. AUTOMATIC mode (AUT) The AUTO mode is highlighted by the lighting of the corresponding green LED. In automatic mode, the unit manages automatically the opening and closing of the contactors and the starting and stopping of generator sets, if required. When the main line voltage is out of bounds for a time longer than those set (line presence green LED turns off), the unit disconnects the load from the priority line and connect it to the secondary or standby line, managing both start-up of any generator and interlock time delay. When the main line comes back within the limits, the unit will switch the load to it and decide the possible cooling cycle of the generator. Auto or manual mains return is programmable.
