Automatic Transfer Switch Control Module


Description

The configurable Automatic Transfer Switch Model ATS107SP allows many of the industry’s demanding specifications to be achieved. The ATS107SP is used to start a generator on a mains outage, sending a signal to the Auto Start Enabled Generator and transfers the load when engine’s operating criteria has been met. The engine's warm-up time before accepting load and cool-down time after relieving load can be set directly on the module (set by 4-pole DIP switch).The ATS107SP allows working on 3 phase and single phase mains/generator supply. Each mains phase is monitored individually.

How it works

Under normal circumstances when mains power is available, National Grid power supply runs through the Automatic Transfer Switch (ATS) contactors* and connects to your distribution board. When mains power fails, the ATS will pause for a 25 sec. period to ensure you haven’t had a power spike. ATS will then initiate a generator start signal (by closing terminals 3 and 4), warm up the generator within pre-set time set by internal programmable timer* (see table A) and then connect the generator power supply to your home or business premises. Upon mains power being restored and stays healthy for more than 25 sec. the reverse happens and the controller automatically transfers load from the generator power back to mains shutting down the generator after a cool-down period (cool-down period = warm-up period) and restoring it to standby mode. The ATS107SP series modules have been designed for DIN rail or/and flat surface mounting.
