Product Introduction

The bidirectional DC power supply adopts bipolar soft switching power supply technology, which has low switching loss, low electromagnetic radiation and high power density, which can meet the testing needs of various motor controller products.

Features

  • Working mode: constant voltage, constant current, constant power three modes 
  • The power supply adopts full-bridge phase-shifting soft switching technology, and the efficiency of the whole machine is more than 90%. 
  • Power factor of power input can reach 0.99 at full load
  • The power supply adopts PWM rectification and DC/DC two-stage circuit, which can achieve the characteristics of wide output voltage range, high precision and fast dynamic response;
  • The bidirectional DC power supply adopts IGBT bidirectional rectification and full-bridge IGBT inverter technology, which has the characteristics of fast transient response speed and short recovery time, which can meet the needs of energy feedback in motor testing.
  • Output voltage accuracy 0.1%FS
  • No need to consume energy under load during the test of electric vehicle motors and charging piles, and can feed back the reverse current to the power grid in real time, which has the outstanding advantages of energy saving, consumption reduction and green environmental protection.
  • RS485 and other remote control communication interfaces, which can be operated locally or by upper computer.
