Lifetime expectancy is specified in operational hours and is calculated according to the capacitor’s manufacturer specification. The prediction model allows only a calculation of up to 15 years from date of shipment. **) 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. 2.2 DS-ML15.121-EN All parameters are specified at 12V, 1.3A, 230Vac input, 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0 Germany 11/25 ML15.121 12V, 1.3A, SINGLE PHASE INPUT MiniLine-2 13.

It can be used for various purposes. The most popular application is to configure highly reliable and true redundant power supply systems. Another interesting application is the separation of sensitive loads from non-sensitive loads. This avoids the distortion of the power quality for the sensitive loads which can cause controller failures.

APPLICATION NOTES 22.1. 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. 22-1 Peak loading with 2x the nominal current for 50ms, typ. Peak load 2.6A (resistive load) for 50ms Output voltage dips from 12V to 7.8V. Fig. 22-2 Peak loading with 5x the nominal current for 5ms, typ. Peak load 6.5A (resistive load) for 5ms Output voltage dips from 12V to 2V. 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). The maximum allowed feed back voltage is 25Vdc. The absorbing energy can be calculated according to the built-in large sized output capacitor which is specified in chapter 6. 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. However, please note that the output voltage can dip to zero for approximately 200ms if the back-feed voltage is removed.

CHARGING OF BATTERIES The power supply can be used to charge 12V lead-acid or maintenance free batteries. Instructions for charging batteries (float charging): a) Ensure that the ambient temperature of the power supply is below 45°C b) 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 c) Use a 2A or 3A circuit breaker (or blocking diode) between the power supply and the battery. d) Ensure that the output current of the power supply is below the allowed charging current of the battery. e) The return current to the power supply (battery discharge current) is typ. 12mA when the power supply is switched off (except in case a blocking diode is utilized). 22.4. 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 3A C-Characteristic breaker should be used. Unit A 22.5. PARALLEL USE TO INCREASE OUTPUT POWER AC + ML15.121 power supplies can be paralleled to increase the output power. This power supply has no feature included which balances the load current DC + between the power supplies. Usually the power supply with the higher Unit B adjusted output voltage draws current until it goes into current limitation. This Load AC means no harm to this power supply as long as the ambient temperature stays + below 45°C. The ML15.121 can not be paralleled with power supplies from the MiniLine series. The output voltages of all power supplies shall be adjusted to DC the same value (±100mV). A fuse or diode on the output of each unit is only required if more than three units are connected in parallel. If a fuse (or circuit breaker) is used, choose one with approximately 150% of the rated output current of one power supply. 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 the bottom and output terminals on top of the unit). Pay attention that leakage current, EMI, inrush current, harmonics will increase when using multiple power supplies.

PARALLEL USE FOR REDUNDANCY Voltage Monitor + + Output + + Output ML15.121 ML15.121 Input Input L N L N I 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 1.3A are paralleled to build a 5.2A redundant system. + - + IN 1 IN 2 MLY10 Load Output + - - + - I L Please note: This simple way to build a redundant system does not N cover failures such as an internal short circuit in the secondary side of the power supply. In such a case, the defect unit becomes a load for the other power supplies and the output voltage can not be maintained any more. This can only be avoided by utilizing decoupling diodes which are included in the redundancy module MLY10.241. Recommendations for building redundant power systems: a) Use separate input fuses for each power supply. b) Monitor the individual power supply units. c) 1+1 Redundancy is allowed up to an ambient temperature of 60°C N+1 Redundancy is allowed up to an ambient temperature of 45°C d) 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 exact same type can be connected in series for higher AC + 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 DC with a potential above 60Vdc are not SELV any more and can be dangerous. + Such voltages must be installed with a protection against touching. Earthing of Unit B Load the output is required when the sum of the output voltage is above 60Vdc. AC 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 / Earth right) between two power supplies and avoid installing the power supplies on DC top of each other. Do not use power supplies in series in mounting orientations other than the standard mounting orientation (input terminals on the bottom and output terminals on top 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 unlimited inductive loads. The max. capacitive load depend on the steady state output current. At 1.3A output current, the output capacity should not be larger than 1 000µF and at 0.65A output current not larger than 2 500µF. In case of larger capacitors, the unit can show start-up attempts or start-up problems.

Please contact PULS if you do not plan to use the PE terminal. A different marking of the front foil is then required. Grounding of the input is beneficial for a high EMI immunity: Symmetrical spikes or fast transients on the input side can be conducted directly to earth by the built-in filter capacitors. The magnitude of such spikes or fast transients on the output side caused by the input is much smaller compared to not connecting this terminal to ground.
