Power Supply


 

An intelligent telecommunication power supply with an extended universal input and output voltage range. Besides unity pf operation and  minimized input line current distortion, intelligent control and protection facilities are integrated into the modules by means of a dual-processor based digital controller. One of the micro controllers is employed for user interface purposes such as long term record, display and alarm facilities. The fast processing speed required by the output voltage setting, current limit and paralleling is  fulfilled by the second micro controller which adjusts the output voltage references of  CPS  power supply modules.
