ESCRIPTION
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
CS20.241 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.
The devices have a power reserve of 20% included,
which may even be used continuously at temperatures
up to +45°C. Additionally, the CS20.241 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.
