4. SOFT-START AND INPUT INRUSH CURRENT SURGE
Inrush current limitation
An active inrush limitation circuit (inrush limiting resistor which is bypassed by a relay contact) limits the input inrush
current after turn-on of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.

Soft-start function:
After the DC/DC converter is turned on, the internal output current rises slowly to its nominal value. This method
charges the output capacitors (internal and external capacitors) slowly and avoids high input currents during turn-on.
High input currents can produce a high voltage drop on the input wiring (especially with long and thin cables) which
reduces the terminal voltage on the DC/DC converter. If the terminal voltage is below the shut-down voltage, the
DC/DC converter will turn-off and will make a new start-up attempt. This effect is avoided with the integrated softstart function. Please note that this function increases the rise time of the output voltage by a small amount.

Peak current capability (up to several milliseconds)
The DC/DC converter can deliver a peak current, which is higher than the specified short term current. This helps to
start current demanding loads or to safely operate subsequent circuit breakers.
The extra current is supplied by the output capacitors inside the DC/DC converter. During this event, the capacitors will
be discharged and causes a voltage dip on the output. Detailed curves can be found in chapter 22.1.

6. HOLD-UP TIME
The input side of the DC/DC converter is equipped with a bulk capacitor which keeps the output voltage alive for a
certain period of time when the input voltage dips or is removed. The bulk capacitor can be discharged by loading the
DC/DC converter on the output side or through a load which is parallel to the input. There is no protection in the
DC/DC converter which prevents current from flowing back to the input terminals. If prevention is needed, an external
diode should be used.

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 prediction model allows only a calculation of up to 15 years from date of shipment.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a

22. APPLICATION NOTES
22.1. PEAK CURRENT CAPABILITY
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.
Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in the branch circuit,
the fuse needs a certain amount of over-current to trip or to blow. The peak current capability ensures the safe
operation of subsequent circuit breakers.
Assuming the input voltage is turned on before such an event, the built-in large sized output capacitors inside the
DC/DC converter can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following
two examples show typical voltage dips:

Output voltage dips from 24V to 11V.
22.2. BACK-FEEDING LOADS
Loads such as decelerating motors and inductors can feed voltage back to the DC/DC converter. This feature is also
called return voltage immunity or resistance against Back- E.M.F. (Electro Magnetic Force).
This DC/DC converter is resistant and does not show malfunctioning when a load feeds back voltage to the DC/DC
converter. It does not matter, whether the DC/DC converter is on or off.
The maximum allowed feed-back-voltage is 30Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitance which is specified in chapter 5.
22.3. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply any kind of loads, including unlimited capacitive and inductive loads.

22.4. CHARGING OF BATTERIES
The DC/DC converter can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series)
Instructions for charging batteries:
a)
Ensure that the ambient temperature of the DC/DC converter is below 45°C
b)
Do not use DC/DC converters in mounting orientations other than the standard mounting orientation (input
terminals on the bottom and output terminals on top of the unit).
c)
Set output voltage (measured at no load and at the battery end of the cable) very precisely to the end-of-charge
voltage.

e)
Ensure that the output current of the DC/DC converter is below the allowed charging current of the battery.
f)
Use only matched batteries when putting 12V types in series.
g)
The return current to the DC/DC converter (battery discharge current) is typ. 26.4mA when the DC/DC converter is
switched off (except in case a blocking diode is utilized).
22.5. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 50A. 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 6A C-Characteristic breaker should be used.
22.6. REQUIREMENTS FOR THE SUPPLYING SOURCE
In certain circumstances, the input filter of the DC/DC converter can show a resonant effect which is caused by the
supplying network. Especially when additional external input filters are utilized, a superimposed AC voltage can be
generated on the input terminals of the DC/DC converter which might cause a malfunction of the unit. Therefore,
additional input filters are not recommended. To avoid the resonant effects, the minimal resistance of the supplying
network which depends on the inductance of the input network, shall be above the boundary curve in Fig. 22-3.

22.7. PARALLEL USE TO INCREASE OUTPUT POWER
Unit A
The DC/DC-converter can be paralleled to increase the output power. There are
no feature included which balances the load current between the DC/DC
converters. Therefore some restrictions and limitations apply. The DC/DC
converter with the higher adjusted output voltage draws current until it goes
into current limitation. This means no harm or switch-off to this DC/DC converter
as long as the ambient temperature stays below 45°C. The CD5.242 can also be
paralleled with power supplies from the DIMENSION CT, QS or QT-series. For
other power supplies consult PULS. Set the “single use / parallel use” jumper to
“parallel use” if such an option is available.

The output voltages of all DC/DC converters shall be adjusted to the same value
(±100mV) at full load. A fuse or diode on the output of each unit is only required if more than three units are
connected in parallel. This avoid that more than 2 times of the nominal output current can flow backwards into the
DC/DC converter in case the output stage of the DC/DC converter has a defect. If a fuse (or circuit breaker) is used,
choose one with approximately 150% of the rated output current of one DC/DC converter. Keep an installation
clearance of 15mm (left / right) between two DC/DC converters and avoid installing the DC/DC converters on top of
each other. Do not use DC/DC converters in parallel in mounting orientations other than the standard mounting
orientation (input terminals on the bottom and output terminals on top of the unit).
22.8. PARALLEL USE FOR REDUNDANCY
The DC/DC converters can be paralleled for 1+1 redundancy to gain higher system availability. Redundant systems
require a certain amount of extra power to support the load in case one DC/DC converter fails. The simplest way is to
put two DC/DC converters in parallel. This is called a 1+1 redundancy. In case one DC/DC converter 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 an N+1 method. E.g. five DC/DC converters, each rated for 5A are paralleled to build a 20A
redundant system.
Furthermore, 1+1 redundant systems can be built by using a DC/DC converter powered from a battery and a power
supply with AC input.
Please note: This simple way to build a redundant system does not cover failures such as an internal short circuit in
the secondary side of the DC/DC converter. In such a case, the defect unit becomes a load for the other DC/DC
converters and the output voltage can not be maintained any more. This can only be avoided by utilizing decoupling
diodes which are included in the decoupling module YRM2.DIODE.
Recommendations for building redundant power systems:
a)
Use separate input fuses for each DC/DC converter.
b)
Monitor the individual DC/DC converter units. A DC-ok lamp and a DC-ok contact is included in the redundancy
module YRM2.DIODE. This feature reports a faulty unit.
c)
1+1 Redundancy is allowed up to an ambient temperature of 60°C
N+1 Redundancy is allowed up to an ambient temperature of 45°C
d)
It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

22.9. DAISY CHAINING OF OUTPUTS
Daisy chaining (jumping from one DC/DC converter output to the next) is allowed as long as the average output
current through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal
block.

Input
DC/DC converters of the exact 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
Output
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. Keep an installation clearance of 15mm (left / right) between
two DC/DC converters and avoid installing the DC/DC converters on top of each
Output
other. Do not use DC/DC converters in series in mounting orientations other than
the standard mounting orientation (input terminals on the bottom and output terminals on top of the unit).

22.11. USE IN A TIGHTLY SEALED ENCLOSURE
When the DC/DC converter is installed in a tightly sealed enclosure, the temperature inside the enclosure will be
higher than outside. In such situations, the inside temperature defines the ambient temperature for the DC/DC
converter.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The DC/DC converter is placed in the middle of the box, no other heat producing items are inside the box

22.12. MOUNTING ORIENTATIONS
Mounting orientations other than input terminals on the bottom and output on the top require a reduction in
continuous output power or a limitation in the max. allowed ambient temperature. The amount of reduction
influences the lifetime expectancy of the DC/DC converter. 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).
