Chroma Systems’ new bidirectional DC power supplies for EV component testing

Chroma Systems Solutions, a provider of power conversion test equipment, is announcing the first-phase release of its new 62000D bidirectional DC power supplies. Bidirectional DC power supplies offer two-quadrant operation with positive current/positive voltage as well as negative current/positive voltage, enabling both DC power output and regenerative DC loading. The absorbed energy feeds back to the grid with a conversion efficiency up to 93% and can operate in constant voltage, constant current, and constant power modes.

Pre-compliant with LV123 and LV148 standards for EV component testing, the 62000D is suitable for testing power components such as bidirectional on-board chargers (BOBC), bidirectional DC converters, and DC-AC motor drivers. It can also perform battery simulations. The 62000D has a high-speed CV dynamic response slope that can be controlled to 180 V/ms which is applicable to the electrical characteristics tests of many vehicle guidelines. 

The 62000D series offers power ratings of 6 kW, 12 kW, and 18 kW, and achieves 180 kW in parallel and series operation. Voltages will range from 0~100 V/600 V/1,200 V/1,800 V with a current rating from 0~540 A.
