Bidirectional DC Power supplies from Chroma provide better control for testing bidirectional EV components, batteries, and PV inverters. The 62000D series of programmable bidirectional DC power supplies features both power source and load characteristics, two-quadrant operation, and allows feedback of power from the device under test. They can also be used for testing renewable energy power systems, including hybrid inverters, power conversion systems (PCS), battery charge/discharge, and are a capable battery simulator.

The 62000D is also suitable for testing power components used in electric vehicles, such as bidirectional on-board chargers (BOBC), bidirectional DC converters, and DC-AC motor drivers, as well as power conversion simulation tests of batteries in both directions.
