Puls CS10.241-S1 Data Sheet

C–Series

1. GENERAL DESCRIPTION

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, existing alongside
the high featured Q-series.

The C series includes all the essential basic functions
and the devices have a power reserve of 20%. This
extra current may even be used continuously at
temperatures up to +45°C. The most important
features are the small size, the high efficiency and
the wide temperature range.

The Auto-select input makes worldwide installation
and usage very simple. Defects or system failures
caused by wrongly set switches can not occur.

TERMINOLOGY AND ABREVIATIONS

PE and symbol PE is the abbreviation for Protective Earth and has the same meaning as the symbol .

Earth, Ground This document uses the term “earth” which is the same as the U.S. term “ground”.

T.b.d. To be defined, value or description will follow later.

AC 230V A figure displayed with the AC or DC before the value represents a nominal voltage with

standard tolerances (usually ±20%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50Hz and AC
120V parameters are valid at 60Hz mains frequency.

230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional

tolerances included.

DISCLAIMER

Peak current capability (up to several ms)

The power supply can deliver a peak current which is higher than the specified short term current. This helps to start
current demanding loads or to safely operate subsequent circuit breakers.

The extra current is supplied by the output capacitors inside the power supply. During this event, the capacitors will
be discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 25.1.

Peak current voltage dips typ. from 24V to 18.5V at 20A for 50ms, resistive load
typ. from 24V to 17.5V

typ. from 24V to 12V

at 50A for 2ms, resistive load
