Auto-ranging DC supply integrated energy-recovering load

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 capability of the PSB 10000 is the unit’s ability to be programmed to seamlessly switch between source and sink with no ‘off’ time. When operating as the load, the device synchronises 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 three-phase input voltage 342-528V, 45 to 66Hz, with output voltage ratings of 60 to 2,000V and current ratings from 40A to 1,000A. 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 1.08MW.
