This range of ATS panels is to be used where the local Mains (primary) supply is backed up by a generating set or secondary power supply. The ATS panel monitors the local Mains supply and will switch to the secondary if this should fail or fall outside pre-set limits. The ATS panel controls the switching of the load from the Mains supply to the standby supply. On return of the Mains supply the ATS panel will monitor it to ensure it is stable and then transfer the load from the standby back to the Mains supply. If the secondary supply is a generator, at this point the ATS panel will request the generator to stop.
A phase failure relay is used for Mains voltage monitoring and offers under and over voltage protection as well as phase sequence. The panel uses two timer relays to control timing functions in the panel. Timer one is used to control the Mains restoration period, this controls the period the Mains supply has to be healthy before engaging the Mains contactor. Timer two controls the standby settling period, this timer is useful for situations when the standby supply is a generator as it ensures the generator has ran up to speed and stabilized before a load is applied to the generator.
