The PS-220/12-2,5 power unit is designed to maintain the continuity of direct 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.
FEATURES
Protection: over current, load short-circuit, battery short-circuit, overvoltage load, battery polarity reversal;
operation with unlimited numbers of the PS power units connected in parallel for power augmentation is available;
there are very low-frequency pulsations (0.25% of nominal voltage );
high degree of the mains
of
220V A.C. output insulation is provided;
overvoltage protection is provided;
a fine adjustment (±50 мV ) of a buffer voltage for a storage battery considerably elongates the SB service life.
