PRODUCT DESCRIPTION
The Dimension CP-Series are cost optimized power
supplies without compromising quality, reliability and
performance. The CP-Series is part of the DIMENSION
power supply family.
The CP5.241 power supplies come with three connection
terminal options: screw, spring-clamp or push-in
terminals, which are optimized for automated wiring.
The CP5.241-C1 is equipped with conformal coated pc-
boards preferred for the use in harsh environments and
the CP5.242 features an enhanced DC input voltage
range.
The most outstanding features of these units are the
small size, the high efficiency, the electronic inrush
current limitation, active PFC and the wide operational
temperature range. The devices have a power reserve of
20% included, which may even be used continuously at
temperatures up to +45°C. Additionally, they can deliver
3 times the nominal output current for 12ms 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 signal contact
for remote monitoring, and a large international
approval package for a variety of applications makes
this unit suitable for nearly every situation.

6. OUTPUT
The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage.
The output 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 > 0.3F are connected to
the output, the unit might charge the capacitor in an intermittent mode.
The output is electronically protected against overload, no-load and short-circuits. In case of a protection event,
audible noise may occur.
Output voltage Nom. 24V
Adjustment range Min. 24-28V Guaranteed value
Max. 30.0V This is the maximum output voltage which can
occur at the clockwise end position of the
potentiometer due to tolerances. It is not a
guaranteed value which can be achieved.
Factory settings Typ. 24.1V ±0.2%, at full load and cold unit
Line regulation Max. 10mV Between 85 and 300Vac
Load regulation Max. 50mV Between 0A and 6A, static value, see Fig. 6-1
Ripple and noise voltage Max. 50mVpp Load >0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Max. 200mVpp Load <0.2A, Bandwidth 20Hz to 20MHz, 50Ohm
Output current Nom. 6A1) At 24V and an ambient temperatures below 45°C
Nom. 5A At 24V and 60°C ambient temperature
Nom. 3.8A At 24V and 70°C ambient temperature

Nom. 4.3A At 28V and 60°C ambient temperature
Nom. 3.2A At 28V and 70°C ambient temperature
Derate linearely between +45°C and +70°
Fuse breaking current Typ. 15A Up to 12ms once every five seconds, see Fig. 6-2.
The fuse braking current is an enhanced transient
current which helps to trip fuses on faulty output
branches. The output voltage stays above 20V.
Overload behaviour Continuous current For output voltage above 13Vdc, see Fig. 6-1
Intermittent current2) For output voltage below 13Vdc, see Fig. 6-1
Overload/ short-circuit current Max. 7.2A Continuous current, see Fig. 6-1
Typ. 9A Intermitted current peak value for typ. 1s
Load impedance 50mOhm, see Fig. 6-3
Discharge current of output capacitors is not
included.
Max. 3.5A Intermitted current average value (R.M.S.)
Load impedance 50mOhm, see Fig. 6-3
Output capacitance Typ. 1 800μF 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) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 1s. After this, the
output is switched off for approx. 9s 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. 6-3.

13. 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.

228 000h 271 000h 336 000h At 24V, 6A and 25°C
14. 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.

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.

18. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground.
The output is insulated to the input by a double or reinforced insulation.
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.
We recommend that either the + pole or the – pole shall be connected to the protective earth system. This helps to
avoid situations in which a load starts unexpectedly or can not be switched off when unnoticed earth faults occur.
