YR40.482 - REDUNDANCY MODULE The YR40.482 is equipped with two input channels (20A each), which are individually decoupled by utilizing mosfet technology. The output current can go as high as 40A. Using mosfets instead of diodes reduces the heat generation and the voltage drop between input and output. Each power supply needs it own redundancy module, since the current of each power supply is greater than the max. rating of 20A of one input of the redundancy module. Both inputs should be connected in parallel. The YR40.482 does not require an additional auxiliary voltage and is self-powered even in case of a short circuit across the output.

APPLICATION NOTES 26.1. REPETITIVE PULSE LOADING Typically, a load current is not constant and varies over time. This power supply is designed to support loads with a higher short-term power demand (=BonusPower®). The short-term duration is hardware controlled by an output power manager and is available on a repeated basis. If the BonusPower® load lasts longer than the hardware controller allows it, the output voltage will dip and the next BonusPower® is available after the BonusPower® recovery time (see chapter 6) has elapsed. To avoid this, the following rules must be met: a) The power demand of the pulse must be below 150% of the nominal output power. b) The duration of the pulse power must be shorter than the allowed BonusPower® time. (see output section) c) The average (R.M.S.) output current must be below the specified continuous output current. If the R.M.S. current is higher, the unit will respond with a thermal shut-down after a period of time. Use the maximum duty cycle curve (Fig. 26-2) to check if the average output current is below the nominal current. d) The duty cycle must be below 0.75.

PEAK CURRENT CAPABILITY The power supply 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 BonusPower®). 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: Fig. 26-3 Peak load with 2x the nominal current for 50ms, typ. Fig. 26-4 Peak load with 5x the nominal current for 5ms, typ. 53.4A Peak load (resistive) for 50ms Output voltage dips from 36V to 28.2V. 133.5A Peak load (resistive) for 5ms Output voltage dips from 36V to 20V. Please note: The DC-OK relay triggers when the voltage dips more than 10% for longer than 1ms. Peak current voltage dips typ. typ. typ. from 36V to 28.2V from 36V to 25.3V from 36V to 20V at 53.4A for 50ms, resistive load at 133.5A for 2ms, resistive load at 133.5A for 5ms, resistive load 26.3. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 30A (U.S.A.) and 32A (IEC). 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 C-Characteristic breaker should be chosen, when the unit is used at AC100 and AC120V mains voltages (including AC 230V). If the unit is used only at AC 230V mains, a 10A B- or CCharacteristic breaker is sufficient.

CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. (Three 12V batteries in series) Instructions for charging batteries: a) 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 41.7V 41.25V 40.8V 40.35V Battery temperature 10°C 20°C 30°C 40°C b) Use a 32A or 40A circuit breaker (or blocking diode) between the power supply and the battery. c) Ensure that the output current of the power supply is below the allowed charging current of the battery. d) Use only matched batteries when putting 12V types in series. e) The return current to the power supply (battery discharge current) is typ. 25mA when the power supply is switched off (except in case a blocking diode is utilized). 26.5. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCB’s or UL1077 circuit breakers) are commonly used for AC-supply systems and may also be used on DC 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 36V 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 section and wire length.

PARALLEL USE TO INCREASE OUTPUT POWER Unit A Power supplies from the same series (Q-Series) can be paralleled to increase the output power. The output voltage shall be adjusted to the same value (±100mV) in “Single use” mode with the same load conditions on all units, or the units can be left with the factory settings. After the adjustments, the jumper on the front of the unit shall be moved from “Single use” to “Parallel use”, in order to achieve load sharing. The “Parallel use” mode regulates the output voltage in such a manner that the voltage at no load is approx. 4% higher than at nominal load. See also chapter 6. If no jumper is plugged in, the unit is in “Single use” mode. Factory setting is also “Single use” mode. AC DC + + Unit B AC DC Load + - - If more than three units are connected in parallel, a fuse or circuit breaker with a rating of 32A or 40A is required on each output. Alternatively, a diode or redundancy module can also be utilized. Energize all units at the same time to avoid the overload HiccupPLUS mode. It also might be necessary to cycle the input power (turn-off for at least five seconds), if the output was in HiccupPLUS mode due to overload or short circuits and the required output current is higher than the current of one unit. 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 (terminals on the bottom of the unit) or in any other condition where a derating of the output current is required (e.g. altitude, above 60°C, …). Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. 26.7. 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 25A are paralleled to build a 100A redundant system. For N+1 redundancy the same restrictions apply as for increasing the output power, see also chapter 26.6. 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 not be maintained any more. 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 25.2. Recommendations for building redundant power systems: a) b) c) d) Use separate input fuses for each power supply. A separate source for each supply when possible increases the reliability of the redundant system. Set the power supply into “Parallel Use” mode. Monitor the individual power supply units. Therefore, use the DC-OK relay contact of the QS40 power supply. It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

SERIES OPERATION Unit A AC 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 not SELV any more and can be dangerous. Such voltages must be installed with a protection against touching. DC + + Unit B AC Earthing of the output is required when the sum of the output voltage is above 60Vdc. DC Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals. 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.

Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies. 26.9. INDUCTIVE AND CAPACITIVE LOADS The unit is designed to supply any kind of loads, including capacitive and inductive loads. If extreme large capacitors, such as EDLCs (electric double layer capacitors or “UltraCaps”) with a capacitance > 1.5F are connected to the output, the unit might charge the capacitor in the HiccupPLUS mode (see chapter 6). 26.10. 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 50Vdc. The absorbing energy can be calculated according to the built-in large sized output capacitor which is specified in chapter 6.

MOUNTING ORIENTATIONS Mounting orientations other than all terminals on the bottom require a reduction in continuous output power or a limitation in the maximum allowed ambient temperature.
