48V 1800W DC Telecom Power Supply Small Size Rectifier Module For BTS / Fiber


Small Size 48V 1800W Rectifier Module DC Telecom Power Supply For BTS / Fiber


The innovative design makes great customer advantages of high efficiency, reliable and cost-effective.



● BTS, fiber and switch telecom

Standard efficiency and high efficiency modules are mixable to maximize cost-saving and power system efficiency.


● Network access


For medium and small power network access, because of giant numbers, the cost-effective and higher efficiency module are key components of power supply operation in indoor/outdoor harsh environment with high reliability.


● Data center, power server and computer


The high efficiency module is also designed for data center to replace UPS power, comparing with UPS’s born disadvantage---low efficiency, low reliability, high maintenance cost, the high efficiency module suits for data center excellently.

● Self protection and reliability


  1. DSP control with advanced software
  2. The basic protection of input/output fuse, and input/output low voltage/over voltage protection, also high level protection of power derated when input low voltage and high temperature, and temperature regulated fan speed, all these functions create high reliability.
  3. Hot-plug and easy maintenance
