Bidirectional Dual-Channel DC Test Power Supply
EVWBT Series

voltage 24~1200V, current 0~1200A (peak 1560A), power 0~600kW (peak 780kW)


EVWBT series Bidirectional Dual- Channel DC Test Power Supply is characterized by a bidirectional flow of energy, which can provide electrical energy for the load and feed the electrical energy back to the electrical grid without pollution, saving the power cost for the user. With two independent DC outputs, the two outputs' voltage, current, and other parameters can be set separately. It applies to the energy feedback- type test bench and can adapt to two motor controllers with different voltage classes.
