Easy World Automation | PULS CPS20.121 DIN-rail Power supply

PULS CPS20.121 DIN-rail Power supply

  • 100-240V Wide-range input, active PFC
  • Efficiency up to 92,5%
  • Negligibly low input inrush current
  • Full output power between -25 and +60°C
  • DC-OK Signal, Parallel mode for load sharing


The Dimension C-Series are cost optimized power supplies without compromising quality, reliability and performance. The C-Series is part of the DIMENSION power supply family. The most outstanding features of CPS20.121 are the high efficiency, electronic inrush current limitation, active PFC, 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. Additionally, the CPS20.121 can deliver about 4 times the nominal output current for 15ms 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.

You can place an order for the PULS CPS20.121 DIN-rail Power supply online via one of our Middle East branches (Dubai/ Oman/Saudi Arabia) and get it delivered at a low cost at a specific time.
