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) HiccupPLUS Mode
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. 6-3.

9. REMOTE ON / OFF FUNCTION (CP20.241-V1 ONLY)
This feature allows to switch-off the power supply output with a signal switch or transistor. A link
between pin 15 and 16 turns the power supply on. Pin 15 is referenced to the (-) output voltage.
The open-loop voltage between pin 16 and pin 15 can be up to 18V. The maximum current, when in
remote ON mode, can be up to 2.5mA.
The threshold level to switch-off the output is typically 5V and the turn-on threshold is typically 9V.
When multiple power supplies are connected in parallel, pin 15 and pin 16 are also allowed to be
paralleled to control all units with the same switch or transistor.

11. 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.

12. 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.

The buffer unit does not require any control wiring. It can be added in parallel to the
load circuit at any given point. Buffer units can be added in parallel to increase the
output ampacity or the hold-up time.
23.2. YR40.241/242 - REDUNDANCY MODULES
The YR40.241 and YR40.242 redundancy modules are equipped with two input channels
(each 20A), which are individually decoupled by utilizing MOSFET technology. The output
current can be as high as 40A. Using MOSFETs instead of diodes reduces the heat
generation and the voltage drop between input and output. The modules do not require
an additional auxiliary voltage and are self-powered even in case of a short circuit across
the output.
Due to the low power losses, the units are very slender and only require 36mm width on
the DIN-rail.
The YR40.241 can be used in combination with any power supply while the YR40.242 is
optimized for use in combination with power supplies featured with the HiccupPLUS
overload behavior. The terminal arrangement of the YR40.242 is reversed to the YR40.241.
Further information and wiring configurations can be found in chapter 24.5.
23.3. YR40.245 - REDUNDANCY MODULES
The YR40.245 is a 40A single channel redundancy module, which is equipped with a plug
connector on the output. The plug connector allows replacing the power supply or the
redundancy module while the system is running. The plug connector avoids that the
output wires can touch and short the load circuit.
The YR40.245 is very slender and only requires 46mm width on the DIN-rail. It also utilizes
MOSFET technology instead of diodes for low heat generation and a minimal voltage drop
between input and output. It does not require an additional auxiliary voltage and is selfpowered even in case of a short circuit across the output.
Further information and wiring configurations can be found in chapter 24.5.

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 (including the PowerBoost). 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 three examples show typical voltage dips for resistive loads:

24.2. 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.

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).
Output
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
24.4. PARALLEL USE TO INCREASE OUTPUT POWER
Power supplies can be paralleled to increase the output power. The output
voltage of all power supplies shall be adjusted to the same value (±100mV) in
“Single use” mode with the same load conditions on all units, or the units can
be left with the factory settings. After the adjustments, set the unit to “Parallel
use” mode, in order to achieve load sharing. 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.
If more than three units are connected in parallel, a fuse or circuit breaker
with a rating of 30A or 32A is required on each output. Alternatively, a diode
or redundancy module can also be utilized.

Energize all units at the same time to avoid the overload HiccupPLUS mode. It
also might be necessary to cycle the input power (turn-off for at least five seconds), if the output was in HiccupPLUS
mode due to 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, above 60°C, …).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

24.5. PARALLEL USE FOR REDUNDANCY
Please note that there are variants with built-in redundancy are available in the CP20 series. Check CP20.241-Rx units.
1+1 Redundancy:
Power supplies can be paralleled for redundancy to gain higher system availability. Redundant systems require a
certain amount of extra power to support the load in case one power supply unit fails. The simplest way is to put two
power supplies in parallel. This is called a 1+1 redundancy. In case one power supply unit fails, the other one is
automatically able to support the load current without any interruption. It is essential to use a redundancy module to
decouple power supplies from each other. This prevents that the defective unit becomes a load for the other power
supplies and the output voltage cannot be maintained any more.
Recommendations for building redundant power systems:
-
Use separate input fuses for each power supply.
Use separate mains systems for each power supply whenever it is possible.
Monitor the individual power supply units. Therefore, use the DC-OK signal of the power supply.
It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.
Set the power supply into “Parallel use” mode.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
N+1 Redundancy:
Redundant systems for a higher power demand are usually built in a N+1 method. E.g. four power supplies, each rated
for 20A are paralleled to build a 60A redundant system.
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
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 or in
any other condition, where a de-rating of the output current is required.

24.9. MOUNTING ORIENTATIONS
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
Curve A2
Recommended output current.
Max allowed output current (results in approximately half the lifetime expectancy of A1).
