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.

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.

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 16A B- or 10A 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.

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. AC DC + + Unit B Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals. DC Load + - Earth (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 QP-Series or CP-Series for charging batteries.

USE IN A TIGHTLY SEALED ENCLOSURE AC L Fuse L2 internal fuse N PE DC 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.

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).
