The shortterm duration is hardware controlled by an output power manager. This BonusPower® is repeatedly available. Detailed information can be found in chapter 22.1. If the power supply is loaded longer with the BonusPower® than shown in the Bonus-time diagram (see Fig. 6-2), the max. output power is automatically reduced to 180/203W. Discharge current of output capacitors is not included. This is the maximum output voltage which can occur at the clockwise end position of the potentiometer due to tolerances. It is not guaranteed value which can be achieved. The typical value is about 15.8V. 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 22.2.

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 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. *) Nov. 2020 / Rev. 2.5 DS-QS10.121-EN All parameters are specified at 12V, 15A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany 10/28 QS10.121 12V, 15A, SINGLE PHASE INPUT Q-Series 11.

YR40.241 - REDUNDANCY MODULE The YR40.241 is the preferred redundancy module for QS10.121 power supplies. It 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. The YR40.241 does not require an additional auxiliary voltage and is self- powered 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. 22.4. YR40.245 - REDUNDANCY MODULE The YR40.245 is a 40A single channel redundancy module, which is equipped with a plug connector on the output. The plug connector allows replacing the power supply or the redundancy module while the system is running. The plug connector avoids that the output wires can touch and short the load circuit. The YR40.245 is very slender and only requires 46mm width on the DIN-rail. It also utilizes mosfet technology instead of diodes for low heat generation and a minimal voltage drop between input and output. It does not require an additional auxiliary voltage and is selfpowered even in case of a short circuit across the output.

APPLICATION NOTES 23.1. 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. 22-2) to check if the average output current is below the nominal current.

From time to time a peak power of 270W (= 150% of the rated output load) is needed for 1 second. The question is: How often can this pulse be supplied without overloading the power supply? - Make a vertical line at PPEAK = 150% and a horizontal line where the vertical line crosses the P0 = 50% curve.

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. 22-3 Peak load with 2x the nominal current for 50ms, typ. Peak load 30A (resistive) for 50ms Output voltage dips from 12V to 10V. Fig. 22-4 Peak load with 4x the nominal current for 5ms, typ. Peak load 60A (resistive) for 5ms Output voltage dips from 12V to 5.2V. Please note: The DC-OK relay triggers when the voltage dips more than 10% for longer than 1ms. 23.3. 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 18Vdc. The absorbing energy can be calculated according to the built-in large sized output capacitor which is specified in chapter 6. 23.4. 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 4A C-Characteristic breaker should be used Nov. 2020 / Rev. 2.5 DS-QS10.121-EN All parameters are specified at 12V, 15A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany 23/28 QS10.121 12V, 15A, SINGLE PHASE INPUT Q-Series 23.5. CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. 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 13.9V 13.75V 13.6V 13.4V Battery temperature 10°C 20°C 30°C 40°C b) Use a 20A 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) The return current to the power supply (battery discharge current) is typ. 5mA when the power supply is switched off (except in case a blocking diode is utilized). 23.6. 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 12V 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 12V 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 AC Power supplies from the same series (Q-Series) can be paralleled to increase the output power.

Alternatively, a diode or redundancy module can also be utilized. Load AC + - - Keep an installation clearance of 15mm (left / right) between two power DC 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 bottom and output terminals on the top 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. 23.8. 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 Failure Monitor interruption. Redundant systems for a higher power demand are usually built in a N+1 method. E.g. five power +- +++ - +- +++ - supplies, each rated for 15A are paralleled to build a 60A IN 1 IN 2 IN 1 IN 2 12V,15A Adj 12V,15A Adj redundant system. For N+1 redundancy the same DCok DCok restrictions apply as for increasing the output power, see Overload Overload QS10.121 QS10.121 also section 22.7. YR2.Diode YR2.Diode 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 decoupling diodes which are included in the redundancy module YR2.DIODE.

Such a phase-to-phase connection is allowed as long as the supplying voltage is below 240V+15%. 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”. L3 AC L Fuse L2 internal fuse N PE DC 23.13. 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: Load: Input: Temperature inside enclosure: Temperature outside enclosure: Temperature rise: Rittal Typ IP66 Box PK 9519 100, plastic, 180x180x165mm 12V, 12A; (=80%) load is placed outside the box 230Vac 46°C (in the middle of the right side of the power supply with a distance of 2cm) 27°C 19K Nov. 2020 / Rev. 2.5 DS-QS10.121-EN All parameters are specified at 12V, 15A, 230Vac, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany 27/28 QS10.121 12V, 15A, SINGLE PHASE INPUT Q-Series 23.14. 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 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 Curve A2 Recommended output current. Max allowed output current (results in approximately half the lifetime expectancy of A1).
