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, springclamp 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.

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 Hiccup
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.

Back-feeding loads
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.

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.

24. APPLICATION NOTES
24.1. PEAK CURRENT CAPABILITY
The unit can deliver peak currents (up to several milliseconds) which are higher than the specified short term currents.
This helps to start current demanding loads. Solenoids, contactors and pneumatic modules often have a steady state
coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady-state
current and usually exceeds the nominal output current. The same situation applies when starting a capacitive load.
The peak current capability also ensures the safe operation of subsequent circuit breakers of load circuits. The load
branches are often individually protected with circuit breakers or fuses. In case of a short or an overload in one branch
circuit, the fuse or circuit breaker need a certain amount of over-current to open in a timely manner. This avoids
voltage loss in adjacent circuits.
The extra current (peak current) is supplied by the power converter and the built-in large sized output capacitors of
the power supply. The capacitors get discharged during such an event, which causes a voltage dip on the output. The
following two examples show typical voltage dips for a resistive load:

A voltage adjustment potentiometer can be found behind the flap on the front of the unit. However, it is not
recommended to change the output voltage since load sharing between power supplies connected in parallel can only
be achieved by a precise setting of the output voltages. The factory settings allow precise load sharing and only
qualified personnel should change the adjustment potentiometer.

24.4. OUTPUT CIRCUIT BREAKERS
Standard miniature circuit breakers (MCB’s or UL 1077 circuit breakers) are commonly used for AC-supply systems and
may also be used on 24V branches.
MCB’s are designed to protect wires and circuits. If the ampere value and the characteristics of the MCB are adapted to
the wire size that is used, the wiring is considered as thermally safe regardless of whether the MCB opens or not.
To avoid voltage dips and under-voltage situations in adjacent 24V branches which are supplied by the same source, a
fast (magnetic) tripping of the MCB is desired. A quick shutdown within 10ms is necessary corresponding roughly to
the ride-through time of PLC's. This requires power supplies with high current reserves and large output capacitors.
Furthermore, the impedance of the faulty branch must be sufficiently small in order for the current to actually flow.
The best current reserve in the power supply does not help if Ohm’s law does not permit current flow. The following
table has typical test results showing which B- and C-Characteristic MCBs magnetically trip depending on the wire cross
section and wire length.

24.5. S
Power supplies of the same type can be connected in series for higher
output voltages. It is possible to connect as many units in series as needed,
providing the sum of the output voltage does not exceed 150Vdc. Voltages
with a potential above 60Vdc must be installed with a protection against
touching.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals.
Keep an installation clearance of 15mm (left / right) between two power
supplies and avoid installing the power supplies on top of each other. Do
not use power supplies in series in mounting orientations other than the
standard mounting orientation (input terminals on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

24.6. PARALLEL USE TO INCREASE OUTPUT POWER
Power supplies can be paralleled to increase the output power. For
redundancy applications one extra power supply is always needed for
sufficient output current in case one unit fails.
The unit is permanently set to “parallel use” mode in order to achieve
load sharing between power supplies connected in parallel. The “Parallel
use” mode regulates the output voltage in such a manner that the voltage
at no load is approx. 4% higher than at nominal load. See also chapter 6.
Energize all units at the same time. It also might be necessary to cycle the
input power (turn-off for at least five seconds), if the output was in
overload or short circuits and the required output current is higher than
the current of one unit.
Keep an installation clearance of 15mm (left / right) between two power supplies and avoid installing the power
supplies on top of each other.
Do not use power supplies in parallel in mounting orientations other than the standard mounting orientation (input
terminals on bottom of the unit) or in any other condition where a derating of the output current is required (e.g.
altitude).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
Do not load paralleled power supplies with higher currents as shown in the following diagrams:

24.7. PARALLEL USE FOR REDUNDANCY
Power supplies can be paralleled for redundancy to gain higher system availability. The unit is already equipped with a
MOSFET as decoupling device on the output to avoid, that a faulty unit becomes a load for the other power supplies
and the output voltage cannot be maintained any more.
Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units by utilizing the built-in DC-OK relay contacts on each power supply.

Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a
limitation in the maximum allowed ambient temperature. The amount of reduction influences the lifetime expectancy
of the power supply. Therefore, two different derating curves for continuous operation can be found below:
Curve A1 Recommended output current.
Curve A2 Max allowed output current (results in approximately half the lifetime expectancy of A1).
