Switch Mode Power Supply (Smps)
For Telecommunication Rectifiers
A combination of modern AC to DC switching power conversion technology and a flexible 19" compatible mechanic like the PSR-T gives many advantages and is suitable for a wide range of applications. Power supply modules of series PSR-T are optimized for telecommunication application. Due to the high flexibility for mounting of complete pre-wired sub racks in system cabinets this system is very easy in use, during commissioning and maintenance. The combination of an active power factor correction unit and a soft-switching DC to DC-converter provides a wide input voltage range, high efficiency, small dimensions, and low weight. A constant voltage and current control circuit performs correction of output voltage deviations due to input voltage or load transients within less than 1.5 ms and permits constant current operation down to continuous short circuit.
