| High Light | 48V 20A telecom rectifier power supply ，DC power supply for communication networks ，Telecom system rectifier with high current | ||
The Compact Telecom DC Rectifier Power Supply is designed for medium-power telecom, network, industrial control, and backup power applications. It provides stable DC power conversion for systems that require reliable operation but do not need a large-scale rectifier cabinet or heavy-duty power architecture.
This model is suitable for telecom hubs, small base stations, network rooms, server racks, security systems, industrial automation equipment, and backup power installations. With a compact rack-mountable design, high conversion efficiency, wide AC input compatibility, and built-in protection functions, it offers a practical power solution for sites where space, efficiency, and reliability are equally important.
Unlike larger modular rectifier systems, this product focuses on easy deployment, stable output, and flexible integration into existing equipment racks. It also supports remote monitoring options, allowing users to check operating status, voltage, current, and temperature through SNMP or Modbus-compatible systems. The backup battery charging function makes it suitable for emergency power and UPS-related applications.
