GENERAL DESCRIPTION
The Dimension C-Series are cost optimized power
supplies and DC/DC converters 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, 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 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.
