PULS CPS20.481-D1 INTRODUCTION
The Dimension C-Series is are cost-optimized power supply and DC/DC converter without compromising quality, reliability, and performance. The C-Series is part of the DIMENSION power supply family. The most outstanding features of CPS20.481-D1 are the wide DC input range, high efficiency, electronic inrush current limitation, and wide operational temperature range.
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 CPS20.481-D1 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 make this unit suitable for nearly every situation.
