Chroma 62000D Series programmable bidirectional DC power supplies have both power source and load characteristics. Capable of feeding power from the device under test (DUT) back to the utility grid, these two-quadrant power supplies are ideal for testing energy storage systems in renewable energy applications such as solar PV/storage hybrid inverters, battery power conditioning systems (PCS), and simulating charging and discharging of energy storage batteries. 62000D also has applications in testing power components in electric vehicles (EVs) as well as bidirectional on-board chargers (BOBC), DC-DC converters, and DC-AC motor drivers, enabling bi-directional power conversion simulation tests without the need for actual batteries.
