4U Rack unit integrates 30KW auto-ranging DC supply with energy-recovering DC load

Published: 26 February 2020 - Rachael Morling

Intepro Systems has announced the availability of its Model PSB 10000 30 KW programmable digital power supply/load. The PSB 10000 Series 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.

The PSB 10000 has the ability to 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. This provides further energy savings by reducing the cooling costs in the test environment

“If you are looking at solutions for charge and discharge testing, the PSB 10000 Series can provide you with a quick ROI and can be easily integrated into existing test environments,” said Gerard Sheehan, Intepro's Chief Technical Officer. 

The PSB 10000 features a wide range 3-phase input voltage 342-528V, 45-66 Hz, with output voltage ratings of 60V – 2,000V and current ratings from 40A-1000A. The device includes a wide range of programmable functions to simulate complex testing such as electric vehicle load profiles, battery charging, PV simulation per EN 50530 and MPP tracking and others. Multiple PSB 10000 units can be operated in a master-slave configuration providing source/load capabilities up to 1.08 MW.
