Bidirectional DC power supply in the use of testing battery, DC controller and DC motor.

XYH series high-precision Bidirectional Dc Power Supply is a bidirectional charging and discharging device. It adopts two-stage conversion structure, IGBT type Dc Power Supply with high precision, high reliability, programmable and automatic operation. The DC output characteristics have high precision and high dynamic response characteristics, and automatic bidirectional operation function. It adopts full digital control, high control accuracy, fast response speed and wide output regulation range. The output has programmable function, which can be applied to a variety of occasions through different control.

The main advantage of XYH series power supply is that it can simulate the power battery to simulate the input power, output current, overload capacity, withstand voltage, motor efficiency, locked rotor current, maximum speed, overspeed, feed and other performance of electric vehicle motor controller. The back EMF energy in the overspeed experiment can be fed back to the power grid in real time to effectively protect the controller from damage.
