Above 45°C, do not use this power/ current longer than a duty cycle of 10% and/ or not longer than 1 minute every 10 minutes. 2) HiccupPLUS Mode At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2s. After this, the output is switched off for approx. 18s before a new start attempt is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device will operate normally. See Fig. 6-3. 3) Discharge current of output capacitors is not included. 4) 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 28.5V (in “single use” mode).

LIFETIME EXPECTANCY 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. AC 100V AC 120V AC 230V Lifetime expectancy 123 000h 149 000h 173 000h At 24V, 10A and 40°C 348 000h 422 000h 488 000h At 24V, 10A and 25°C 48 000h 60 000h 94 000h At 24V, 20A and 40°C 136 000h 169 000h 265 000h At 24V, 20A and 25°C 23 000h 31 000h 54 000h At 24V, 24A and 40°C 64 000h 88 000h 152 000h At 24V, 24A and 25°C 11. MTBF 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. For these types of units the MTTF (Mean Time To Failure) value is the same value as the MTBF value.

ACCESSORIES 23.1. UF20.241 BUFFER MODULE This buffer unit is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after turn-off of the AC power. In times when the power supply provides sufficient voltages, the buffer unit stores energy in integrated electrolytic capacitors. In case of mains voltage fault, this energy is released again in a regulated process. One buffer module can deliver 20A additional current. DC Buffer Unit(s) Power Supply LoadAC The buffer unit does not require any control wiring. It can be added in parallel to the load circuit at any given point. Buffer units can be added in parallel to increase the output ampacity or the hold-up time. 23.2. YR40.242 - REDUNDANCY MODULES The YR40.242 redundancy module is equipped with two input channels (each 20A), which are individually decoupled by utilizing MOSFET technology. The output current can be as high as 40A. Using MOSFETs instead of diodes reduces the heat generation and the voltage drop between input and output. The YR40.242 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. Further information and wiring configurations can be found in chapter 24.7. 23.3. YR40.245 - REDUNDANCY MODULES 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 circu it. 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 self- powered even in case of a short circuit across the output. Further information and wiring configurations can be found in chapter 24.7.

APPLICATION NOTES 24.1. 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 examples show typical voltage dips: Fig. 24-1 Peak load with 2x the nominal current for 50ms, typ. Fig. 24-2 Peak load with 5x the nominal current for 5ms, typ. 10ms/DIV Output Voltage Output Current 24V 40A 16V 1ms/DIV Output Voltage Output Current 24V 100A 17V 40A Peak load (resistive) for 50ms Output voltage dips from 24V to 16V. 100A Peak load (resistive) for 5ms Output voltage dips from 24V to 17V.

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. 24.3. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 30A (UL) 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 10A B- or C-Characteristic breaker should be used. 24.4. 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 section and wire length.

SERIES OPERATION 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. Unit A Input Output Unit B Load Input Output Avoid return voltage (e.g. from a decelerating motor or battery) which is applied to the output terminals. 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. 24.6. PARALLEL USE TO INCREASE OUTPUT POWER CP20 power supplies can be paralleled to increase the output power. The output voltage of all power supplies 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, set the unit to “Parallel use” mode, 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 more than three units are connected in parallel, a fuse or circuit breaker with a rating of 30A or 32A 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. Unit A Unit B Load Input Output Input Output 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 (input terminals on 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.

PARALLEL USE FOR REDUNDANCY CP20 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 20A are paralleled to build a 80A redundant system. For N+1 redundancy the same restrictions apply as for increasing the output power, see also chapter 24.6. Please note: Always use a redundancy module to decouple power supplies from each other or use power supplies with built in redundancy like the CP20.241-R1 (spring-clamp terminals), the CP20.241-R2 (plug connectors for hot swap) or the CP20.241-R3 (screw terminals). This prevents that the defective unit becomes a load for the other power supplies and the output voltage cannot be maintained any more. Recommendations for building redundant power systems: a) Use separate input fuses for each power supply. b) Set the power supply into “Parallel use” mode. c) Monitor the individual power supply units. Therefore, use the DC-OK relay contact of the CP20 power supply. d) It is desirable to set the output voltages of all units to the same value (± 100mV) or leave it at the factory setting.

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 > 1F are connected to the output, the unit might charge the capacitor in the HiccupPLUS® mode (see chapter 6). 24.9. CHARGING OF BATTERIES The power supply can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VRLA batteries are needed in series connection. 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 27.8V 27.5V 27.15V 26.8V Battery temperature 10°C 20°C 30°C 40°C b) Use a 30A or 32A 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) Ensure that the ambient temperature of the power supply stays below 40°C. e) Use only matched batteries when putting 12V types in series. f) The return current to the power supply (battery discharge current) is typ. 3.5mA when the power supply is switched off (except in case a blocking diode is utilized). 24.10. OPERATION ON TWO PHASES 240V +10% max. L N PE Power Supply AC DC The power supply can also be used on two-phases of a three-phase- system. Such a phase-to-phase connection is allowed as long as the supplying voltage is below 240V+10%. 24.11. 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: Rittal Typ IP66 Box PK 9519 100, plastic, 180x180x165mm Load: 24V, 16A; (=80%) lo ad is placed outside the box Input: 230Vac Temperature inside enclosure: 51.7°C (i n the middle of the right side of the power supply with a distance of 2cm) Temperature outside enclosure: 25.9°C Temperature rise: 25.8K

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. 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 (res ults in approximately half the lifetime expectancy of A1).
