TH24T50ZZ Intelligent Communication Rectifier Module
1.5KW High-Reliability Power Supply for Telecom & Industrial Systems
The TH24T50ZZ is a state-of-the-art intelligent high-frequency switching power module designed for demanding 24V communication systems. Utilizing advanced "Resonant Voltage Dual-Loop Control" technology, this module delivers exceptional efficiency (up to 90%), a compact footprint, and superior reliability. Equipped with a standard RS-485 interface, it seamlessly integrates with automated monitoring systems to support "Four Remote Functions" (Remote Control, Regulation, Measurement, and Signaling). Ideal for integration with PBX systems, base stations, and various communication equipment.
Key Features
High Efficiency & Power Factor: Achieves an efficiency of 88%~90%. Features a "Three-phase Passive PFC Circuit" with a power factor of 0.92, eliminating the need for a neutral wire.
Intelligent Parallel Operation: Utilizes isolation autonomous current sharing technology with an imbalance of < ±3%. Supports parallel operation of over 20 modules.
Built-in Protection: Integrated DC output isolation diode and comprehensive protection circuits (Over-Voltage, Short-Circuit, Over-Temperature, Over-Current).
Robust & Maintenance-Free: Fully encapsulated design ensures stable operation even in harsh environments.
Digital Communication: Standard RS-485 interface for data display, fault alarms, and remote system integration.

Comprehensive Protection System
Safety is the top priority in power conversion. The TH24T50ZZ features multiple layers of protection to safeguard both the module and your connected devices:
Output Over-Voltage Protection (OVP): Features an internal OVP circuit. If triggered, the module locks automatically to prevent damage to downstream equipment.
Short-Circuit Protection: Uses a Retractable Droop (Foldback) Current Limiting method. The module can remain in a short-circuit state indefinitely without damage and will automatically recover once the fault is cleared.
Over-Temperature Protection: Automatically shuts down if the heatsink temperature exceeds 90℃ and restarts automatically when the temperature drops.
Phase Loss Protection: If any input phase is lost, the module reduces its maximum current limit to 25A and triggers an input anomaly alarm.
