Product Description

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 1400W (24V) or 1680W (48V) or 3000W(110V) or 3000V(220V). 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
