Product Introduction

The TH48T50ZZ-220 is a high-power, intelligent 48V/50A (3KW) communication power supply module designed for demanding telecommunication systems. Utilizing advanced resonant power conversion technology, it features a natural convection (self-cooling) design for silent operation and high reliability. With its standard RS-485 interface, it seamlessly integrates into automated systems for comprehensive "Four-Remote" monitoring and control.

Product Advantages

High Power with Silent Operation: Delivers 3KW of stable 48V DC power using a reliable, fan-less natural cooling design, eliminating noise and moving part failures.
Robust & Intelligent: Offers ≥92% efficiency and supports remote monitoring, control ("Four-Remote" functions), and stable parallel operation with excellent current sharing (±3%).
Comprehensive Protection: Built-in protections against over-voltage, short-circuit, over-temperature, and input abnormalities ensure safe operation for both the module and connected equipment.
Wide Input Range: Compatible with a broad DC input voltage (198-242VDC), providing strong grid adaptability.

Application Scenarios

Ideal for core telecommunication infrastructure and other high-power DC applications:

Telecommunication Hubs: Powering central office equipment, large program-controlled switches, and core network nodes requiring high-current 48V power.
Industrial Control Systems: Serving as a reliable power source in environments where silent operation and high reliability are critical.
Backup Power Systems: Acting as a key rectifier module in large-scale DC backup power systems for critical facilities.

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.
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.

Insulation Strength

Test	Specification	Result
Input to Chassis	1600VAC 1 min 5mA	No dielectric breakdown or flashover
Input to Output	1600VAC 1 min 4mA	No dielectric breakdown or flashover
Output to Chassis	600VAC 1 min 4mA	No dielectric breakdown or flashover
