800 vdc output 6251000 kw dc power supply system cabinet-0

800 VDC Output, 625–1000 kW DC Power Supply System Cabinet

Introduction

This product is an 800 VDC power supply system cabinet with a rated power range of 625–1000 kW. The series supports AC input systems with rated voltages of 380 V, 400 V, 415 V, and 480 V at 50 or 60 Hz, delivering a stable 800 VDC output to the load. It integrates five to eight three-phase AC-DC power conversion modules, individual AC input circuit breakers for each module, a main AC input switch, leakage current detection and protection, and a system controller (SC). N+1 module redundancy is supported. The cabinet also provides low- and high-voltage ride-through (LVRT and HVRT), adjustable output voltage, hot-swappable modules, communication and operating-fault alarms, and comprehensive overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature protection.

Core Advantages

High-Voltage DC Power Supply Uses high-frequency PFC rectification for AC-DC power conversion, achieving a power factor above 0.99. The 800 VDC output meets the power-supply requirements of AIDC facilities.
Modular Power Redundancy A modular, hot-swappable design supports system power expansion and redundant configurations, improving the reliability and maintainability of the power supply system.
High Efficiency Full silicon carbide (SiC) power devices enable highly efficient AC-DC rectification, with peak efficiency reaching 99%.
Remote OTA Upgrade Supports external TCP communication and online over-the-air (OTA) firmware upgrades.
Fault Ride-Through, Alarm & Protection Provides low-voltage and high-voltage ride-through capability (LVRT and HVRT), together with comprehensive fault alarms and protection. Functions include module communication and operating-fault alarms, plus overvoltage, undervoltage, overcurrent, short-circuit, and overtemperature protection.
