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
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.

21. APPLICATION NOTES
21.1. 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
power supply can deliver extra current. Discharging this capacitor causes a voltage dip on the output. The following
two examples show typical voltage dips:
Fig. 21-1 Peak loading with 2x the nominal
current for 50ms, typ.
Fig. 21-2 Peak loading with 5x the nominal
current for 5ms, typ.
Peak load 6A (resistive load) for 50ms
Output voltage dips from 5.1V to 2.4V.
Peak load 15A (resistive load) for 5ms
Output voltage dips from 5.1V to 0.8V.
21.2. 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).
The maximum allowed feed back voltage is 6.3Vdc. The absorbing energy can be calculated according to the built-in
large sized output capacitor which is specified in chapter 6.
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. However, please note that the output voltage can dip to
zero for approximately 200ms if the back-feed voltage is removed.

21.3. EXTERNAL INPUT PROTECTION
The unit is tested and approved for branch circuits up to 20A. 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 3A C-Characteristic breaker should be used.

ML15.051 power supplies can be paralleled to increase the output power. This
power supply has no feature included which balances the load current

between the power supplies. Usually the power supply with the higher
Unit B
adjusted output voltage draws current until it goes into current limitation. This
Load
AC
means no harm to this power supply as long as the ambient temperature stays
+
below 45°C. The ML15.051 can also be paralleled with power supplies from
MiniLine series with 5V output voltage. The output voltages of all power
DC
supplies shall be adjusted to the same value (±100mV). A fuse or diode on the
output of each unit is only required if more than three units are connected in parallel. If a fuse (or circuit breaker) is
used, choose one with approximately 150% of the rated output current of one power supply. 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 the bottom and output terminals on top of the unit). Pay attention that leakage current, EMI,
inrush current, harmonics will increase when using multiple power supplies.

21.5. 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
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 3A are paralleled to build a 12A
redundant system.
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 power supply. In such a case, the defect unit becomes a load for the other power supplies
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 MLY02.100.
Recommendations for building redundant power systems:
a)
Use separate input fuses for each power supply.
b)
Monitor the individual power supply units.
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.
21.6. SERIES OPERATION
Unit A
Power supplies of the exact same type can be connected in series for higher
AC
+
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
DC
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
Unit B
Load
the output is required when the sum of the output voltage is above 60Vdc.
AC
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 /
Earth
right) between two power supplies and avoid installing the power supplies on
DC
top of each other. Do not use power supplies in series in mounting
orientations other than the standard mounting orientation (input terminals on the bottom and output terminals on
top of the unit). Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple
power supplies.
21.7. INDUCTIVE AND CAPACITIVE LOADS
The unit is designed to supply unlimited inductive loads.
The max. capacitive load depend on the steady state output current. At 3A output current, the output capacity should
not be larger than 10 000µF and at 0.3A output current not larger than 25 000µF. In case of larger capacitors, the unit
can show start-up attempts or start-up problems.

Such a phase-to-phase connection is allowed as long as the supplying

input. The N input is internally not protected and is in this case connected
to a hot wire. Appropriate fuses or circuit breakers are specified in section

From a safety standpoint, the unit is internally designed according to the requirements for Protection Class 1 and 2.
Please contact PULS if you do not plan to use the PE terminal. A different marking of the front foil is then required.
Grounding of the input is beneficial for a high EMI immunity: Symmetrical spikes or fast transients on the input side
can be conducted directly to earth by the built-in filter capacitors. The magnitude of such spikes or fast transients on
the output side caused by the input is much smaller compared to not connecting this terminal to ground.

21.10. USE IN A TIGHTLY SEALED ENCLOSURE
When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure will be higher

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 power supply. Therefore, two different derating curves for continuous
operation can be found below:
