modular design rectifier system Introduction
High Efficiency Telecom Rectifier
SETEC mini rack mounting Telecom Rectifier System can offer dc power to communications system. It is high cost efficiency. It is consisted of rectifier module, controller module (also called monitor module), distribution and shelf. It's convenient to configure multiple modules as you like. DC power supply system is base on advanced rectifier modules. Each rectifier can offer high-power output 2100W (24V rectifier each module) or 3000W (48V rectifier each module). The controller module can manage the whole DC power supply system. There is large LCD on controller, English display. All the parameter and alarms can display on the LCD
