Product Description
The DIMENSION C-series are cost-optimised power supplies without compromising quality, reliability and performance. The C-series is part of the DIMENSION power supply family. The most outstanding features of CPS20.241 are the high efficiency, electronic inrush current limitation, active PFC and the wide operational temperature range. The small size is achieved by a synchronous rectification and further technological design details. The C-series includes all the essential basic functions. The devices have a power reserve of 20 % included, which may even be used continuously at temperatures up to +45°C. Additionally, the CPS20.241 can deliver about 4 times the nominal output current for 15 ms which helps to trip fuses on faulty output branches. High immunity to transients and power surges as well as low electromagnetic emission, a DC-OK relay contact and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
