Product Introduction

Product Introduction:

The equipment consists of a master unit and a slave unit. Each set of master and slave units includes a distribution unit and a power unit. The mutual assistance master unit is installed at the transformer end to convert 380V AC into ±375V DC for power supply. The mutual assistance slave unit is installed at the user end to convert ±375V DC into 380/220V AC. Through AC-DC hybrid distribution technology, energy mutual assistance between the transformer side and the end-user side within the transformer zone is achieved, solving the problem of voltage limit violations at the end of long lines in the transformer zone.

Product Features:

  1. High safety, reliable design, and high protection level.
  2. Modular design.
  3. Optimized meter reading functionality.
  4. Remote maintenance by the main station and active fault reporting.
