Overview

The new high-efficiency three-phase PFC circuit topology is adopted, the power factor is greater than 0.99, and the harmonic distortion rate is ≤5%.

The high-frequency switching power supply module adopts full-bridge phase-shift soft-switching technology, and the execution efficiency is high.

The advanced digital current sharing technology effectively improves the current sharing accuracy and anti-interference; the first module sleep technology and the wheeling technology ensure the high-efficiency operation of the system;

Intelligent charging process control and perfect charging process monitoring and protection, fool-like operation;

One button is automatically filled with simple and practical;

Display the charging voltage, current, SOC and other information and operating status in real time, and display the charging degree after charging is completed;

Module hot swap technology makes maintenance more convenient;

Working environment temperature -20+50 °C.

Scope of application

Portable DC charging piles for private use (private cars, logistics vehicles, trucks, etc.)

The operating company leases with the car.

The yard is delivered with the car;

Particularly suitable for rapid deployment where the site is limited.
