ESCRIPTION
The CP20.241-M1 is a DIN rail mountable single-phase-
input power supply for use in industrial and medical
equipment. It provides a stable and galvanically
separated SELV/PELV output voltage.
The specialty of this power supply is the 2MOPP (two
means of patient protection) safety approval for medical
use and the fulfillment of the required EMC tests for
professional healthcare facility and home healthcare
environments.
The CP-Series is part of the DIMENSION power supply
family. The most outstanding features of CP20.241-M1
are the high efficiency, advanced inrush current
limitation, active PFC and the wide operational
temperature range.
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.
