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.

Protection Features
- Automatic Current Limiting: Once the output current reaches the set current limit, the module
automatically switches to constant current operation.
- 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.
