Product Introduction

CRH5011 Series DC distribution board is a DC-DC conversion, DC-AC drive, DC-AC inverter, AC-DC rectification and other integrated drive-distribution-charging system. Each set of DC distribution board contains several AFE rectifier, DC converter, propulsion inverter, daily inverter, LCL filter, SIN filter, LDC filter, circuit breaker, fuse and other equipment devices.


Product Features

DC distribution board adopts left and right segment symmetrical design, and the bus switch (solid switch or disconnecting switch with fuse protection) is divided into two sections. Under the condition of normal operation, the bus switch remains closed. When unilateral bus fails, the solid switch or disconnecting switch fuse will be automatically broken and the fault bus isolation can be realized to ensure the normal operation of the ship.
