Description

HAT220A/HAT240A ATS controller has microprocessor as its core, can accurately detect 2 ways-3 phase, 2 ways-1 phase or 2ways-2phase voltage and also can make accurate judgment to conditions of abnormal voltage (loss of electricity, over or under voltage), control ATS to transfer after delay. Controller also has a function of sending start signal to genset when one power is abnormal.

Performance and characteristics

Controller detect multi-voltage  conditions, such as 2ways-3phase voltage, 1phase voltage (could be 2 ways  mains, 2ways gens, or 1mains-1gens), or 2ways-2phase voltage.
