17. DIELECTRIC STRENGTH
The output voltage is floating and has no ohmic connection to the ground. Type and factory tests are conducted by the manufacturer.
Field tests may be conducted in the field using the appropriate test equipment which applies the voltage with a slow ramp (2s up and 2s
down). Connect all input-terminals together as well as all output poles before conducting the test. When testing, set the cut-off current
settings to the value in the table below.

To fulfil the PELV requirements according to EN60204-1 § 6.4.1, we
recommend that either the + pole, the – pole or any other part of the
output circuit shall be connected to the protective earth system. This helps
to avoid situations in which a load starts unexpectedly or can not be
switched off when unnoticed earth faults occur.

21.3. YRM2.DIODE - REDUNDANCY MODULES
(2x 10A Inputs, 1x 20A output)
The YRM2.DIODE is a dual redundancy module, which can be used to build 1+1 and N+1
redundant systems. It is equipped with two input channels, which are individually decoupled by
utilizing diodes.
The YRM2.DIODE does not require an additional auxiliary voltage and is self-powered even in
case of a short circuit across the output.
The YRM2.DIODE has a monitoring circuit included and is the perfect solution when the power
supply has no DC-OK function. Two LEDs and two relay contacts signal when one of the two DCinput voltages is not in range due to a non-functioning or disconnected power supply.
Due to the compact design, the unit is very slender and only requires 32mm width on the DIN
rail.
21.4. YR40.241 - REDUNDANCY MODULES
(2x 20A input, 1x 40A output)
The YR40.241 is a dual redundancy module, which can be used to build redundant systems. It
is equipped with two input channels, which are individually decoupled by utilizing MOSFET
technology.
Using MOSFET instead of diodes reduces the heat generation and the voltage drop between
input and output. The YR40.241 does not require an additional auxiliary voltage and is selfpowered even in case of a short circuit across the output.
Due to the low power losses, the unit is very slender and only requires 36mm width on the DIN
rail.

22. APPLICATION NOTES
22.1. 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:

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).
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 35Vdc. The absorbing energy can be calculated according to the built-in large sized output
capacitor which is specified in chapter 6.
22.3. 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 10A B- or 6A C-Characteristic breaker should be used.
22.4. 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 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 chapter and wire length.

22.5. PARALLEL USE TO INCREASE OUTPUT POWER
The power supply shall not be used in parallel to increase the output current.
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, see also chapter 22.5.
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 defective unit becomes a load for the other power supplies and the output voltage can no
longer be maintained. This can be avoided by utilizing redundancy modules, which have decoupling devices (diodes or MOSFETs)
included. Further information and wiring configurations can be found in chapter 21.3.
Recommendations for building redundant power systems:
a)
b)
c)
Use separate input fuses for each power supply.
Monitor the individual power supply units.
Therefore, use the DC-OK relay contact of the YRM2.DIODE.
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
Unit A
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 no
longer SELV and can be dangerous. Such voltages must be installed with a protection
against touching.
AC
Earthing of the output is required when the sum of the output voltage is above 60Vdc.

(see notes)
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).
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 any kind of loads, including capacitive and inductive loads.
22.9. CHARGING OF BATTERIES
The power supply shall not be used to charge batteries. Choose power supplies of the QS-Series or CP-Series for charging batteries.

22.12. MOUNTING ORIENTATIONS
Mounting orientations other than the input 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).
