GENERAL DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability and
performance. The most outstanding features of the
CP10.241–R1/-R2/-R3 units are the high efficiency,
electronic inrush current limitation, active PFC, wide
operational temperature range and the extraordinary
small size. The units include a decoupling MOSFET for
building 1+1 or n+1 redundant power supply systems.
These redundancy power supplies come with three
connection terminal options; screw terminals, spring-
clamp terminals or plug connector terminals which
allows replacement on an active application.
CP10.242-R2 version feature an enhanced DC input
voltage range.
With high immunity to transients and power surges, low
electromagnetic emission, a DC-OK signal contact for
remote monitoring, and a large international approval
package, makes this unit suitable for nearly every
application.

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 ±15%) included.
E.g.: DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V)
230Vac A figure with the unit (Vac) at the end is a momentary figure without any additional
tolerances included.
50Hz vs. 60Hz As long as not otherwise stated, AC 230V parameters are valid at 50Hz mains frequency.
may A key word indicating flexibility of choice with no implied preference.
shall A key word indicating a mandatory requirement.
should A key word indicating flexibility of choice with a strongly preferred implementation.
1+1 Redundancy Use of two identical power supplies in parallel to provide continued operation following most
failures in a single power supply. The two power supply outputs should be isolated from each
other by utilizing diodes or other switching arrangements. E.g. two 10A power supplies are
needed to achieve a 10A
redundant system.
N+1 Redundancy Use of three or more identical
power supplies in parallel to
provide continued operation
following most failures in a
single power supply. All power
supply outputs should be
isolated from each other by
utilizing diodes or other
switching arrangements.
E.g.: To achieve a 40A redundant system, five 10A power supplies are needed in a N+1
redundant system.

6. OUTPUT
The output provides a SELV/PELV/ES1 rated voltage, which is galvanically isolated from the input voltage. The output
of the devices includes a decoupling MOSFET for building 1+1 or n+1 redundant power supply systems.
The device is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large
capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance larger than 1.5F are
connected to the output, the unit might charge the capacitor in the HiccupPLUS mode.
The device is featured with a “soft output regulation characteristic” in order to achieve current share between
multiple devices when they are connected in parallel. The “soft output regulation characteristic” regulates the output
voltage in such a manner that the voltage at no load is approx. 4% higher than at nominal load.
Output voltage Nom. DC 24V 23.8 - 25.2V
Adjustment range See chapter 24.2
Factory settings typ. 24.1V ±0.2%, at 10A, cold unit (results to typ. 23.9V±0.2% at
12A and typ. 25.1V±0.2% at no load)
Line regulation Max. 10mV 85-300Vac
Load regulation Typ. 1000mV Static value, 0A Æ10A; see Fig. 6-1
Ripple and noise voltage Max. 50mVpp 20Hz to 20MHz, 50Ohm
Output current Nom. 12A1) Below 45°C ambient temperature, see Fig. 17-1
Nom. 10A At 60°C ambient temperature, see Fig. 17-1
Nom. 7.5A At 70°C ambient temperature, see Fig. 17-1
Fuse breaking current2) Typ. 30A Up to 12ms once every five seconds, see Fig. 6-3.
Overload protection Included Electronically protected against overload, no-load
and short-circuits. In case of a protection event,
audible noise may occur.
Overload behaviour Continuous current Output voltage >13Vdc, see Fig. 6-1
Intermitted current3) Output voltage <13Vdc, see Fig. 6-1
Overload/ short-circuit current Max. 15.5A Continuous current, see Fig. 6-1
Typ. 14A Intermitted current peak value for typ. 2s
Load impedance 10mOhm, see Fig. 6-2.
Discharge current of output capacitors is not included.
Max. 5A Intermitted current average value (R.M.S.)
Load impedance 10mOhm, see Fig. 6-2.
Output capacitance Typ. 4 400μF Included inside the power supply
Back-feeding loads Max. 35V The unit is resistant and does not show
malfunctioning when a load feeds back voltage to
the power supply. It does not matter whether the
power supply is on or off. The absorbing energy can
be calculated according to the built-in large sized
output capacitor.
1) This current is also available for temperatures up to +70°C with a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes.
2) The fuse braking current is an enhanced transient current which helps to start heavy loads or to trip fuses on faulty output branches. The
output voltage stays above 20V. See chapter 24.1 for additional measurements.
3) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the
output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload
exists. If the overload has been cleared, the device will operate normally. See Fig. 6-2.

10. LIFETIME EXPECTANCY
The Lifetime expectancy shown in the table indicates the minimum operating hours (service life) and is determined by
the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours and
is calculated according to the capacitor’s manufacturer specification. The manufacturer of the electrolytic capacitors
only guarantees a maximum life of up to 15 years (131 400h). Any number exceeding this value is a calculated
theoretical lifetime which can be used to compare devices.

11. MTBF
MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates
reliability of a device. It is the statistical representation of the likelihood of a unit to fail and does not necessarily
represent the life of a product.
The MTBF figure is a statistical representation of the likelihood of a device to fail. A MTBF figure of e.g. 1 000 000h
means that statistically one unit will fail every 100 hours if 10 000 units are installed in the field. However, it can not
be determined if the failed unit has been running for 50 000h or only for 100h.
For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

1) In case of an internal defect, a redundant circuit limits the maximum output voltage. The output shuts down and automatically attempts to
restart.
2) Temperature sensors are installed on critical components inside the unit and turn the unit off in safety critical situations, which can happen
e.g. when ambient temperature is too high, ventilation is obstructed or the de-rating requirements are not followed. There is no correlation
between the operating temperature and turn-off temperature since this is dependent on input voltage, load and installation methods.

19. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground. Type and routine tests are conducted by
the manufacturer. Field tests may be conducted in the field using the appropriate test equipment which applies the
voltage with a slow ramp (2s up and 2s down). Connect all input-terminals together as well as all output poles before
conducting the test. When testing, set the cut-off current settings to the value in the table below.

It is recommend that either the + pole, the – pole or any other part
of the output circuit shall be connected to the earth/ground system.
This helps to avoid situations in which a load starts unexpectedly or
can not be switched off when unnoticed earth faults occur.
B*) When testing input to DC-OK ensure that the maximal voltage between DC-OK and the output is not exceeded (column D). We
recommend connecting DC-OK pins and the output pins together when performing the test.
