4U Rack unit integrates auto-ranging dc supply with dc load

January 31, 2020  Stephen Law

INTEPRO SYSTEMS Model PSB 10000 30KW programmable digital power supply/load is a microprocessor controlled bi-directional supply that features two devices in one: an electronic dc load with energy recovery and an auto-ranging dc power supply. This allows for two-quadrant operation in an efficient and easy-to-use instrument. Combining the features of a programmable source and regenerative programmable load into one chassis frees up rack space and reduces generated heat all while recovering loaded energy back to the grid. Unit can be programmed to seamlessly switch between source and sink with no ‘off’ time. When operating as the load, the device synchronizes with its 3-phase power input to recover upwards of 93% of the energy. When operating as a source, the unit has an efficiency of up to 93%, generating less heat in both modes.
