Bidirectional DC Test Power Supply

EVWB Series

Voltage 24~1200V, Current 0~1200A (peak 1560A) , Power 0~600kW (peak 780kW)

The EVWB series bi-directional dc test power supply is characterized by bi-directional flow, which can not only provide power for load, but also feedback power to the power grid without pollution, saving space and cost for users. It built- in five kinds of (Lithium iron phosphate/ternary lithium/lithium manganate/lithium cobaltate/lead- acid)battery models; support IV curve preview; support user- defined five battery models.support parallel operation function.

It applies to preliminary research and development, later type tests, reliability tests in electric motors, and factory tests of production line products.
