Product Overview
The TH48T50ZZ is a robust, intelligent 48V/50A (3KW) switching power supply module designed for high-power telecommunication and industrial systems. It operates from a standard three-phase 380VAC input and utilizes advanced "resonant voltage-type dual-loop control" technology for high efficiency and reliability. Equipped with an RS-485 interface, it seamlessly integrates into automated monitoring and control systems, enabling comprehensive "Four-Remote" functionality for intelligent power management.
Key Advantages
High-Power Three-Phase Input: Designed for 304-456VAC three-phase input, providing efficient and stable power conversion for demanding high-capacity applications.
High Efficiency & Power Factor: Delivers ≥92% efficiency with a high input power factor (≥0.93), reducing energy loss and improving grid-side performance.
Comprehensive Protection & Management: Features robust protections including output over-voltage, short-circuit, over-temperature, and phase-loss protection. Supports full remote monitoring, control, and battery management.
Scalable & Reliable System Integration: Supports N+1 hot-standby configuration and excellent parallel current sharing (±3%), allowing for smooth system expansion and ensuring high availability.

Protection Features
Automatic Current Limiting: Once the output current reaches the set current limit, the module automatically switches to constant current operation, preventing any further increase in output current.
Overvoltage Protection: If the output voltage exceeds 60-63 VDC, the module automatically stops output to prevent damage to connected equipment.
Phase Loss Protection: When any AC mains phase is missing, the module reduces the maximum output current limit to 25 A ±0.5 A and triggers an "Input Abnormal" alarm. Once the input returns to normal, the module restores the normal current limit.
Short-Circuit Protection: During an output short-circuit, the module self-protects to prevent damage. After the fault is cleared, normal operation is automatically restored.
