GENERAL DESCRIPTION
The DIMENSION CP-Series units are high-end power
supplies in a medium price range without compromising
quality, reliability and performance. The CP-Series is
part of the DIMENSION power supply family. The most
outstanding features of CP10.481 are the high
efficiency, advanced inrush current limitation, active PFC
and the wide operational temperature range.
The CP-Series includes all the essential basic functions.
The devices have a power reserve of 10% up to +60°C
and 20% up to +45°C included, which may even be used
continuously. Additionally, the CP10 can deliver three
times the nominal output current for at least 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 relay contact
and a large international approval package for a variety
of applications makes this unit suitable for nearly every
situation.

1) Power Boost
This power/ current is continuously allowed up to an ambient temperature of 45°C.
Above 45°C, do not use this power/ current longer than 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 26V), 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
3) Discharge current of output capacitors is not included.

10. LIFETIME EXPECTANCY AND MTBF
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. LIFETIME EXPECTANCY AND 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 cannot be
determined if the failed unit has been running for 50 000h or only for 100h.

Output protection Electronically protected against overload, no-load and short-circuits. In case of a
protection event, audible noise may occur.
Output over-voltage protection Typ. 58.5Vdc
Max. 60Vdc
In case of an internal power supply defect, a redundant
circuit limits the maximum output voltage. The output
shuts down and automatically attempts to restart.
Degree of protection IP 20 EN/IEC 60529
Penetration protection > 4mm E.g. screws, small parts
Over-temperature protection Yes Output shut-down with automatic restart.
The temperature sensor is installed on critical
components inside the unit and turns the unit off in
safety critical situations (e.g. de-rating requirements
not observed, high ambient temperature, ventilation
obstructed or the mounting orientation de-rating is 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.

23.3. REDUNDANCY MODULES
YR2.DIODE – 2x 10A Inputs, 1x 20A output
The YR2.DIODE is a dual redundancy module, which has two diodes as decoupling devices
included. It can be used for various purposes. The most popular application is to configure
highly reliable and true redundant power supply systems. Another interesting application is
the separation of sensitive loads from non-sensitive loads. This avoids the distortion of the
power quality for the sensitive loads which can cause controller failures.
The YR2.DIODE does not require an additional auxiliary voltage and is self-powered even in
case of a short circuit across the output.
The unit is very slender and only requires 32mm width on the DIN-rail.
YR40.482 – 2x 20A Inputs, 1x 40A output
The YR40.482 is equipped with two input channels, which are individually decoupled by
utilizing MOSFET technology. Using MOSFETs instead of diodes reduces the heat generation
and the voltage drop between input and output. The YR40.482 does not require an
additional auxiliary voltage and is self-powered even in case of a short circuit across the
output.
Due to the low power losses, the unit is very slender and only requires 46mm width on the
DIN-rail.

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 two examples show typical voltage dips for resistive loads:

24.2. BACK-FEEDING LOADS
Loads such as decelerating motors and inductors can feed voltage back to the power supply. This feature is also called
return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
This power supply 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 maximum allowed feed-back-voltage is 63Vdc. The maximum allowed feed-back peak current is 21A. Higher
currents can temporarily shut-down the output voltage. The absorbing energy can be calculated according to the
built-in large sized output capacitor which is specified in chapter 6.
24.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 30A (UL) and 32A (IEC). An external protection is only
required if the supplying branch has an ampacity greater than this. Check also local codes and local requirements. In
some countries local regulations might apply.
If an external fuse is necessary or utilized, minimum requirements need to be considered to avoid nuisance tripping of
the circuit breaker. A minimum value of 6A B- or C-Characteristic breaker should be used.
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 48V 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 48V 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. PARALLEL USE TO INCREASE OUTPUT POWER
CP10.481 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) with the same load conditions on all units, or the units can be left
with the factory settings. There is no feature included which balances the load
current between the power supplies. Usually the power supply with the higher
adjusted output voltage draws current until it goes into current limitation. This
means no harm to this power supply as long as the ambient temperature stays
below 40°C.

If more than three units are connected in parallel, a fuse or circuit breaker
with a rating of 10A or 12A 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.
Restrictions:
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
(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.
24.6. PARALLEL USE FOR 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
decoupled 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. Redundant systems for a higher power
demand are usually built in a N+1 method. E.g. five power supplies, each rated for 5A are paralleled to build a 20A
redundant system. For N+1 redundancy the same restrictions apply as for increasing the output power, see also
chapter 24.5.

Please note: Always 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. Further information and
wiring configurations can be found in chapter 23.3.
Recommendations for building redundant power systems:
a) Use separate input fuses for each power supply.
b) Monitor the individual power supply units. Therefore, use
the DC-OK relay contact of the CP10 power supply.
c) It is desirable to set the output voltages of all units to the
same value (± 100mV) or leave it at the factory setting.

(see notes)
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 are not SELV any more and can be dangerous.
Such voltages must be installed with a protection against touching.
Earthing of the output is required when the sum of the output voltage is
above 60Vdc.
Avoid return voltage (e.g. from a decelerating motor or battery) which is
applied to the output terminals.
Restrictions:
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 (terminals
on bottom of the unit).
Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.
24.8. INDUCTIVE AND CAPACITIVE LOADS
The unit 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 0.5F are connected to the
output, the unit might charge the capacitor in the HiccupPLUS mode (see chapter 6).
24.9. CHARGING OF BATTERIES
The power supply can be used to charge lead-acid or maintenance free batteries (SLA or VRLA batteries). Four 12V
batteries are needed in series.
Instructions for charging batteries:
a) Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge
voltage.
End-of-charge voltage 55.6V 55.0V 54.3V 53.6V
Battery temperature 10°C 20°C 30°C 40°C
b) Use a 10A or 12A circuit breaker (or blocking diode) between the power supply and the battery.
c) Ensure that the output current of the power supply is below the allowed charging current of the battery.
d) Use only matched batteries when putting 12V types in series.
e) Ensure that the ambient temperature of the power supply stays below 40°C.
f) The return current to the power supply (battery discharge current is typ. 1.8mA when the power supply is
switched off (except in case a blocking diode is utilized).

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