The PS-220/12-2,5 D. C. power supply is designed to provide uninterrupted D. C. voltage service for industrial devices and systems.
The PS-220/12-2,5 unit provides a battery charge capacity up to 4A•h in a floating service when a voltage in the mains exists and a load current is 0.6A. The unit provides the battery protection from deep discharge. The PS-220 is equipped with a conductively isolated output for the alarm system that cuts-in on the mains of 220 V A.C. failure.
