EVWBT Bidirectional double-circuit DC Test Power

The EVWBT series bidirectional double-circuit 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. With two independent DC outputs, the output voltage, current and other parameters can be set respectively. It is especially suitable for the energy feedback towing test bench, and can adapt to motor controllers of different voltage levels. It is continuously adjustable within the full range of voltage 24~800V (1000V), current 0~1000A (peak 1300A)/power 0~500KW (peak 650KW).
