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. 1.5 DS--ML60.122-EN All parameters are specified at 12V, 4.5A, 230Vac 50Hz 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 ML60.122 12V, 4.5A, SINGLE PHASE INPUT MiniLine-2 13.

MLY10.241 - REDUNDANCY MODULE The MLY10.241 is a dual redundancy module, which has two diodes with a common cathode included. 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. The same situation applies when starting a motor or switching-on a capacitive load. In many cases, the peak current capability also ensures a safe operation of subsequent circuit breakers. Branch circuits are often protected with circuit breakers or fuses. In case of a short or an overload in a branch circuit, the fuse needs a certain amount of over-current to trip or to blow. 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 9A (resistive load) for 50ms Output voltage dips from 12V to 7V. Fig. 22-2 Peak loading with 5x the nominal current for 5ms, typ. Peak load 22.5A (resistive load) for 5ms Output voltage dips from 12V to 3.7V. 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). 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 25Vdc. The absorbing energy can be calculated according to the built-in large sized output capacitor which is specified in chapter 5.

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 6A 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 typical 6mA 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 + ML60.122 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 ML60.122 can also be paralleled with other power supplies from MiniLine series with 12V output voltage. The output voltages of all DC power supplies shall be adjusted to 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). Be aware that leakage current, EMI, inrush current and harmonics will increase when using multiple power supplies in parallel.

PARALLEL USE FOR REDUNDANCY Voltage Monitor 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 4.5A are paralleled to build a 18A redundant system. + + - Output + + - Output ML60.122 ML60.122 Input Input L N L + - + IN 1 IN 2 N MLY10 Load Output + - - + - I I L Please note: This simple way to build a redundant system does not cover N 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) Use separate mains systems for each power supply whenever it is possible. c) Monitor the individual power supply units. d) 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. e) 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. DAISY CHAINING OF OUTPUTS Daisy chaining (jumping from one power supply output to the next) is allowed as long as the average output current through one terminal pin does not exceed 25A. If the current is higher, use a separate distribution terminal block. Fig. 22-3 Daisy chaining of outputs Fig. 22-4 Using distribution terminals max 25A!

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). Be aware that leakage current, EMI, inrush current and harmonics will increase when using multiple power supplies in series. 22.10. OPERATION ON TWO PHASES Power Supply L1 AC 240V +10% max. The power supply can also be used on two-phases of a three-phase-system. A phase-to-phase connection is allowed as long as the supplying voltage is below 240V+10%. Use a fuse or a circuit breaker to protect the N input. The N input is not internally 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 L Fuse internal fuse N PE DC L2 22.11. USE WITHOUT PE ON THE INPUT From a safety standpoint, the unit is internally designed according to the requirements for Protection Class 1 and 2. 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.

USE AT LOW TEMPERATURES (-25°C / -40°C) Please pay attention to the following aspects when operating the unit at low temperatures. Perform tests to verify suitability in your application. - The ripple & noise voltage will increase. For the first minutes after turning on the unit at -40°C, the ripple an noise voltage can be up to typically 400mVpp depending on load and input voltage. Once the unit heats up, the ripple & noise voltage will decrease typically to 90mVpp. - The start-up delay can be up to 5 seconds. It is a continuous turn-on process without any voltage dips or startup attempts. 22.13. 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.
