Product Overview
The TH48D30ZZ-220 is an intelligent 48V/30A (1440W) switching power supply module specifically engineered for communication systems. It features advanced resonant switching technology for reliable performance and supports both 220V AC and DC input, offering deployment flexibility. Equipped with a standard RS-485 interface, it enables easy integration into automated monitoring and control networks for "Four-Remote" functionality.
Key Advantages
  • Optimized for Communication Systems: Specifically designed for compatibility with program-controlled switches and various telecommunication equipment.
  • Dual Input Flexibility: Supports both AC (187-253VAC) and DC (198-286VDC) input, allowing for versatile installation in different power environments.
  • Reliable & Smart Operation: Offers essential protection features (over-voltage, short-circuit, over-temperature), remote monitoring via RS-485, and stable parallel operation with excellent current sharing (<±5%).
  • Compact & Efficient: Provides a compact footprint with over 90% efficiency, balancing performance with energy savings for continuous operation.
Application Scenarios
  • Telecommunication Infrastructure: Powering core network equipment, program-controlled switches, and base station systems requiring reliable 48V DC power.
  • General Communication Equipment: Serving as a dedicated power source for a wide range of communication and electronic devices compatible with 48V systems.
  • Small to Medium Backup Systems: Acting as a core component in DC power systems or battery backup solutions for critical communication nodes.

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

The output will automatically shut down if the voltage exceeds 62.5–63 VDC to protect connected equipment from damage

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.
