ESCRIPTION
A compact size, light weight, simple mounting onto the
DIN-rail and the utilization of only quality components
are what makes the MiniLine power supplies so easy to
use and install within seconds.
A rugged electrical and mechanical design as well as a
high immunity against electrical disturbances on the
mains provides reliable output power. This offers
superior protection for equipment which is connected
to the public mains network or is exposed to a critical
industrial environment.
The MiniLine series offers output voltages from 5 to
56Vdc and a power rating from 15W to 120W.
The supplementary MiniLine decoupling diode module
MLY10.241 allows building of redundant systems or to
protect against back-feed voltages.

Peak current capability (up to several milliseconds)
The power supply 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 power supply. 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.

*) 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.

The MLY10.241 is a dual redundancy module, which has two diodes with
a common cathode 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.

PPLICATION

OTES
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
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. 22-1 Peak loading with 2x the nominal
current for 50ms, typ.
Fig. 22-2 Peak loading with 5x the nominal
current for 5ms, typ.
Peak load 2.6A (resistive load) for 50ms
Output voltage dips from 12V to 7.8V. Peak load 6.5A (resistive load) for 5ms
Output voltage dips from 12V to 2V.
22.2. 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 25Vdc. 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.

22.3. CHARGING OF BATTERIES
The power supply can be used to charge 12V lead-acid or maintenance free batteries.
Instructions for charging batteries (float charging):
a) Ensure that the ambient temperature of the power supply is below 45°C
b) 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 13.9V 13.75V 13.6V 13.4V
Battery temperature 10°C 20°C 30°C 40°C
c) Use a 2A or 3A circuit breaker (or blocking diode) between the power supply and the battery.
d) Ensure that the output current of the power supply is below the allowed charging current of the battery.
e) The return current to the power supply (battery discharge current) is typ. 12mA when the power supply is
switched off (except in case a blocking diode is utilized).
22.4. 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.
22.5. PARALLEL USE TO INCREASE OUTPUT POWER
ML15.121 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
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 45°C. The ML15.121 can not be paralleled with power supplies from the
MiniLine series. The output voltages of all power 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.

22.6. 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 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 1.3A are paralleled to build a
5.2A 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
redundancy module MLY10.241.
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.
22.7. SERIES OPERATION
Power supplies 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 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 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 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.
22.8. 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 1.3A output current, the output capacity
should not be larger than 1 000µF and at 0.65A output current not larger than 2 500µF. In case of larger capacitors,
the unit can show start-up attempts or start-up problems.

22.9. OPERATION ON TWO PHASES
The power supply can also be used on two-phases of a three-phase-system.
Such a phase-to-phase connection is allowed as long as the supplying
voltage is below 240V+10%. Use a fuse or a circuit breaker to protect the N
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
22.4 “External Input Protection”.
22.10. USE WITHOUT PE ON THE INPUT
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.

22.11. 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
than outside. In such situations, the inside temperature defines the ambient temperature for the power supply.
The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.
The power supply is placed in the middle of the box, no other heat producing items are inside the box
Enclosure: Rittal Type IP66 Box PK 9510 100, plastic, 130x130x75mm
Input: 230Vac
Case A:
Load: 12V, 1.3A; load is placed outside the box
Temperature inside the box: 38.9°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 28.0°C
Temperature rise: 10.9K
Case B:
Load: 12V, 1.05A; (=80%) load is placed outside the box
Temperature inside the box: 33.9°C (in the middle of the right side of the power supply with a distance of 1cm)
Temperature outside the box: 27.4°C
Temperature rise: 8.5K

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 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).
