Especially when additional external input filters are used, a superimposed AC voltage can be generated on the input terminals of the DC/DC converter. This superimposed AC voltage might cause a malfunction of the unit. Therefore, additional input filters are not recommended. To avoid the resonant effects, the minimal resistance of the supplying network which depends on the inductance of the input network, shall be above the boundary curve in Figure 5.

This method charges the output capacitors (internal and external capacitors) slowly and avoids high input currents during turn-on. High input currents can produce a high voltage drop on the input wiring (especially with long and thin cables) which reduces the terminal voltage on the DC/DC converter. If the terminal voltage is below the shutdown voltage, the DC/DC converter turns off and makes a new startup attempt. This effect is avoided with the integrated soft start function. This function increases the rise time of the output voltage by a small amount. Output The output provides a SELV/PELV rated voltage, which is galvanically isolated from the input voltage and is designed to supply any kind of loads, including unlimited capacitive and inductive loads. The output is electronically protected against overload, no-load, and shortcircuits. If there is a protection event, audible noise may occur.

The bulk capacitor can be discharged by loading the DC/DC converter on the output side or through a load that is parallel to the input. There is no protection in the DC/DC converter that prevents current from flowing back to the input terminals. If prevention is needed, use an external diode. At no load, the hold-up time can be up to several seconds. The green DC OK status indicator is also on during this time.

Lifetime expectancy is specified in operational hours and is calculated according to the manufacturer specification of the capacitor. The manufacturer of the electrolytic capacitors only states a maximum life of up to 15 years (131,400 hr). Any number that exceeds this value is a calculated theoretical lifetime, which can be used to compare devices. Attribute Lifetime expectancy Mean Time Between Failure 299,000 hr At 24V, 5 A and 40 °C (104 °F) 103,000 hr At 24V, 10 A and 40 °C (104 °F) 56,000 hr At 24V, 12 A and 40 °C (104 °F) 844,000 hr At 24V, 5 A and 25 °C (77 °F) 292,000 hr At 24V, 10 A and 25 °C (77 °F) 159,000 hr At 24V, 12 A and 25 °C (77 °F) Mean Time Between Failure (MTBF) 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. An MTBF value of, for example, 1,000,000 hr means that statistically one unit fails every 100 hours if 10,000 units are installed in the field. However, it cannot be determined if the failed unit has been running for 50,000 hr or only for 100 hr.

The device is equipped with two input channels, each 10 A nominal, which are individually decoupled using diode technology. The output can be loaded with nominal 20 A. The device does not require an additional auxiliary voltage and is self-powered even if there is a short circuit across the output. The device has a monitoring circuit and is the perfect choice when the power supply has no DC OK function. Two light-emitting diodes (LEDs) and two relay contacts signal when one of the two input voltages is not in range due to a nonfunctioning or disconnected power supply. The unit is slender and only requires 32 mm (1.26 in.) width on the DIN rail. See Parallel Use for Redundancy on page 26 for wiring information. 1606-XLSBUFFER24 Buffer Module The 1606-XLSBUFFER24 buffer module is a supplementary device for 24V DC/DC converters. It delivers power to bridge typical supply voltage faults or extends the hold-up time after turn-off of the input power. In times when the DC/DC converter provides sufficient voltages, the buffer module stores energy in integrated electrolytic capacitors. If there is a supply voltage fault, this energy is released again in a regulated process. The buffer module does not require any control wiring. It can be added in parallel to the load circuit at any given point. One buffer module can deliver 20 A additional current. Buffer modules can be added in parallel to increase the output ampacity or the hold-up time. 22 Rockwell Automation Publication 1606-RM115A-EN-P - September 2020 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 loads that have a high demand for current. 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 capacitive load. The peak current capability also helps ensure the safe operation of subsequent circuit breakers of load circuits. The load branches are often individually protected with circuit breakers or fuses. If there is a short or an overload in one branch circuit, the fuse or circuit breaker need a certain amount of overcurrent 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: Figure 35 - Peak Loading with 2x the Nominal Current for 50 ms, Typ Figure 36 - Peak Loading with 4x the Nominal Current for 5 ms, Typ Peak load 20 A (resistive load) for 50 ms Output voltage dips from 24V to 16V. Peak load 40 A (resistive load) for 5 ms Output voltage dips from 24V to 6V. Attributes Peak current voltage dips Values Notes Typ 24V dips to 16V At 20 A for 50 ms, resistive load Typ 24V dips to 12V At 40 A for 2 ms, resistive load Typ 24V dips to 6V At 40 A for 5 ms, resistive load Rockwell Automation Publication 1606-RM115A-EN-P - September 2020 23 Output Circuit Breakers Standard miniature circuit breakers (MCBs or UL 1077 circuit breakers) are commonly used for AC supply systems and may also be used on 24V branches. MCBs 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 undervoltage situations in adjacent 24V branches that are supplied by the same source, a fast (magnetic) tripping of the MCB is desired. A quick shutdown within 10 ms is necessary corresponding roughly to the ride-through time of PLCs. 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 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. The following test results indicate the maximal wire length for a magnetic (fast) tripping. The wire length is always two times the distance to the load (+ and - wire).

Two 12V SLA or VLRA batteries are needed in series connection. Instructions for charging batteries: • • Ensure that the ambient temperature of the device is below 45 °C (113 °F).

Ensure that the output current of the device is below the allowed charging current of the battery. Use only matched batteries when putting 12V types in series. The return current to the device (battery discharge current) is 10 mA typ when the device is switched off, except if a blocking diode is used. Do not use the devices for battery charging in any condition where a reduction of the output current is required, such as mounting orientations other than the standard mounting orientation, or altitude.

It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150V DC. Voltages with a potential above 60V DC must be installed with a protection against touching. Avoid return voltage (for example, from a decelerating motor or battery) which is applied to the output terminals. Keep an installation clearance of 15 mm (0.59 in.) (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. EMI and inrush current increase when using multiple devices. Parallel Use to Increase Output Power Figure 39 - Parallel Use to Increase Output Power Unit A Input + - Output Unit B Input Load + + - Output - Devices can be paralleled to increase the output power. Either the output voltage shall be adjusted to the same value (±100 mV) with the same load conditions on all devices, or the devices can be left with the factory settings. The ambient temperature is not allowed to exceed 45 °C (113 °F). If more than three devices are connected in parallel, a fuse or circuit breaker with a rating of 15 A or 16 A is required on each output. Alternatively, a diode or redundancy module can be used. Keep an installation clearance of 15 mm (0.59 in.) (left / right) between two devices and avoid installing devices on top of each other. Do not use devices in parallel in any condition where a reduction of the output current is required, such as a mounting orientation other than the standard mounting orientation, or altitude. EMI and inrush current increase when using multiple devices. Rockwell Automation Publication 1606-RM115A-EN-P - September 2020 25 Parallel Use for Redundancy This section covers 1+1 redundancy and N+1 redundancy using the 1606-XLERED redundancy module. 1+1 Redundancy Devices 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 device fails. The simplest way is to put two devices in parallel. This is called a 1+1 redundancy. In case one device fails, the other one is automatically able to support the load current without any interruption. It is essential to use a redundancy module to decouple devices from each other. This helps prevent the defective unit from becoming a load for the other device and helps to ensure that the output voltage is maintained. EMI and inrush current increase when using multiple devices. 1+1 redundancy allows ambient temperatures up to 70 °C (158 °F). Recommendations for building redundant power systems: • • • Use separate input fuses for each device. Use separate supply systems for each device whenever it is possible. Monitor the outputs of the individual devices. Use the DC OK status indicator, or the Redundancy OK contact, which is included in the 1606-XLERED20Y redundancy module, but is not included in the 1606-XLERED redundancy module. It is desirable to set the output voltages of all devices to the same value (± 100 mV) or leave it at the factory setting. • Figure 40 - 1+1 Redundant Configuration for 10 A Load Current Using the 1606-XLERED Failure Monitor DC/DC Converter Input + I + +- +- o oo o Input Input 1 2 2 1 Input ok Redundancy Module + + - Output DC/DC Converter Input Output +- + I +-+- o oo o Input Input 1 2 2 1 Input ok Redundancy Module Output +optional + + - Output - Functional Earth 26 Rockwell Automation Publication 1606-RM115A-EN-P - September 2020 Load N+1 Redundancy Redundant systems for a higher power demand are usually built in an N+1 method. For example, four devices, each rated for 10 A are paralleled to build a 30 A redundant system. EMI and inrush current increase when using multiple devices. For N+1 redundancy the ambient temperature is not allowed to exceed 45 °C (113 °F). Keep an installation clearance of 15 mm (0.59 in.) (left / right) between two devices and avoid installing the devices on top of each other. Do not use devices in parallel in any condition where a reduction of the output current is required, such as in mounting orientations other than the standard mounting orientation, or altitude.

In such situations, the inside temperature defines the ambient temperature for the device. In the following test setup, the device is placed in the middle of the enclosure; no other heat producing items are inside the enclosure. The load is placed outside the enclosure. The temperature sensor inside the enclosure is placed in the middle of the right side of the device with a distance of 1 cm (0.39 in.).
