Product Overview
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.

- Overvoltage Protection: If the output voltage exceeds 60-63 VDC, the module automatically stops output to prevent equipment damage.
- Short-Circuit Protection: During an output short-circuit, the module self-protects and automatically restores normal operation after fault clearance.
- Insulation Strength: Comprehensive dielectric testing ensures safety and reliability.
Application Scenarios
- 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.
