DCPS

General Details

DCPS is a digitally controlled SMPS based DC power supply cum battery charger unit. It consists of 3 SMPS modules and 1 controller module to control and monitor all SMPS modules for load sharing. Each SMPS module supports up to 6A of load. Both float voltage and boost current is adjustable and pre-settable as per user requirements. It is also fully protected against overload and short circuit. Battery temperature compensation is also provided in case of high temperature rise in battery. It meets EMI/EMC safety standards as per EN norms.
