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

CPS20.481 are the high efficiency, electronic inrush

current

limitation,

active

PFC,

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 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.
