WA20KM series EV charger power module

Product introduction

Product Introduction

WA20KM series charger module is a low-voltage and high-current charging power supply module with two industry-leading advantages: ultra-wide output voltage range and ultra-large charging current. High reliability, high efficiency, high power factor, high power density, wide constant power curve, wide operating temperature, and low standby power consumption are also the main features of this module.

Main Features

  1. Wide output voltage range, 200Vdc~1000Vdc.
2. Wide operating temperature range at full power, -40℃~75℃;
  3. Full load efficiency is higher than 95%, high efficiency in the whole working range, and more energy saving;
4. high frequency transformer isolation;
  5. low standby power consumption less than 10W;
6. The current in the low-voltage area does not shrink, and the charging speed is faster;
7. CAN bus communication;
8. The module is built with residual pressure relief loop to reduce system cost and improve system reliability.
