ZYC Simpo HV Pro Power Distribution Unit (PDU)

Overview

The ZYC Simpo HV Pro Power Distribution Unit (PDU) is the control and power-distribution hub of the ZYC Simpo HV Pro high-voltage battery energy storage system. It integrates the master battery management system (BMS), the main circuit breaker (MCB) and the high-voltage power terminals that link the battery module stack to the inverter (PCS).

Rated for 200–1000 Vdc operation at up to 250 A, one PDU controls a rack of up to 11 Simpo HV Pro modules and coordinates protection, communication, black-start and remote monitoring — with up to 16 racks connected in parallel for large commercial & industrial deployments.
