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. |
