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.
■ APPLICATIONS
● 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
- DSP control with advanced software
- 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.
- Hot-plug and easy maintenance
