Product Overview
The WattPower DC Power System (GZDW Series) is a new-generation industrial-grade DC operating power solution, independently developed for power systems, industrial facilities, and infrastructure applications. It adopts high-frequency switch-mode rectifier technology with intelligent control architecture.
Built with a high-performance processor and 7-inch full-color touchscreen HMI, the system provides real-time monitoring of all operating parameters, automatic fault diagnosis with location display, and comprehensive data logging with high-precision GPS time-stamping for efficient fault tracing and resolution.
Key Features
- High-frequency SMPS Technology — Advanced high-frequency switch-mode rectifier modules with ≥94% efficiency, compact design, and low harmonic distortion
- Intelligent Touchscreen HMI — 7-inch full-color touchscreen with real-time system status display, fault auto-diagnosis, and Chinese/English menu operation
- N+1 Redundant Design — Modular hot-swappable rectifier configuration with automatic current sharing (≤5% imbalance) for zero single-point failure
- Smart Battery Management — Temperature-compensated charging, automatic capacity testing, battery health monitoring, and float/equalize charge auto-switching
- Comprehensive Protection — Complete over-voltage, over-current, over-temperature, short-circuit, reverse-polarity, and Class C surge protection
- Flexible Communication — RS485/RS232/Ethernet with MODBUS, IEC 60870-5-103, and IEC 61850 protocol support for seamless SCADA and substation integration
