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.
**) MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statisticalrepresentation 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 failevery 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 YRM2.DIODE is a dual redundancy module, which can be used to build redundant systems. It isequipped 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 ashort 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 DC-input 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.

C-Line22. 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. 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 breakerneed 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 typicalvoltage 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.

C-Line22.3. 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 anampacity 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. PARALLEL USE TO INCREASE OUTPUT POWER
The power supply shall not be used in parallel to increase the output current.

22.5. PARALLEL USE FOR REDUNDANCYPower 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 22.4.
Please note: This simple way to build a redundant system does not cover failures such as an internal short circuit in the secondary sideof the power supply. In such a case, the defective unit becomes a load for the other power supplies and the output voltage can nolonger 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.

22.6. CHARGING OF BATTERIESThe power supply shall not be used to charge batteries. Choose power supplies of the QS-Series for charging batteries.

C-Line22.7. 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 theoutput voltage does not exceed 150Vdc. Voltages with a potential above 60Vdc are nolonger 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 andavoid installing the power supplies on top of each other. Do not use power supplies in series in mounting orientations other than thestandard 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 LOADSThe unit is designed to supply any kind of loads, including capacitive and inductive loads.

22.9. OPERATION ON TWO PHASESPower Supply

The power supply can also be used on two-phases of a three-phase-system. A phase-tophase connection is allowed as long as the supplying voltage is below 240V+10%.

240V +10% max.

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

C-Line22.11. MOUNTING ORIENTATIONSMounting 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).
