Output The output is designed to supply any kind of loads, including capacitive and inductive loads. If capacitors with a capacitance > 3 F are connected to the output, the unit might charge the capacitor in an intermittent mode. Example capacitors with a capacitance > 3 F may include electric double layer capacitors (EDLCs or UltraCaps). The output is electronically protected against overload, no-load, and shortcircuits. If there is a protection event, audible noise may occur.

It does not matter whether the power supply is on or off. The absorbing energy can be calculated according to the built-in large sized output capacitor. (1) At heavy overloads (when output voltage falls below 13V), the power supply delivers continuous output current for 2…5 s. After this, the output is switched off for approximately 7 s before a new start attempt with duration of 1 s is automatically performed. This cycle is repeated as long as the overload exists. If the overload has been cleared, the device operates normally.

Lifetime expectancy is specified in operational hours and is calculated according to manufacturer specification of the capacitor. The manufacturer of the electrolytic capacitors only states a maximum life of up to 15 years (131,400 h). Any number exceeding this value is a calculated theoretical lifetime which can be used to compare devices.

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 value is a statistical representation of the likelihood of a device to fail. An MTBF value of for example 1,000,000 h 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 h or only for 100 h. For these types of units, the mean time to failure (MTTF) value is the same value as the MTBF value.

The output is insulated to the input by a double or reinforced insulation. The manufacturer constructs type and routine tests. Field tests may be conducted in the field using the appropriate test equipment, which applies the voltage with a slow ramp (2 s up and 2 s down). Connect all input-terminals together, and all output poles before conducting the test. When testing, set the cutoff current settings to the value in the table below. We recommend that either the + pole or the – pole shall be connected to the protective earth system. This helps to avoid situations in which a load starts unexpectedly or cannot be switched off when unnoticed earth faults occur.

The device is equipped with two 20 A nominal input channels, which are individually decoupled by using MOSFET technology. The output can be loaded with a nominal 40 A continuous current. Using MOSFETs instead of diodes reduces heat generation, losses and voltage drop between input and output. Due to these advantages, the unit is narrow and only requires 36 mm (1.42 in.) width on the DIN rail. The device does not require an additional auxiliary voltage and is self-powered even if there is a short circuit across the output. It requires suitable power supplies on the input, where the sum of the continuous short circuit current stays below 26 A. This is typically achieved when the power supplies are featured with an intermittent overload behavior (Hiccup Mode). See Parallel Use for 1+1 Redundancy on page 22 for wiring information. 1606-XLBRED20 Redundancy Module The 1606-XLBRED20 is a dual redundancy module, which can be used to build 1+1 or N+1 redundant systems. The device is equipped with two 10 A nominal input channels, which are individually decoupled by using diode technology. The output can be loaded with a nominal 20 A continuous current. The device does not require an additional auxiliary voltage and is self-powered even if there is a short circuit across the output. The unit is narrow and only requires 39 mm (1.54 in.) width on the DIN rail. See Parallel Use for 1+1 Redundancy on page 22 for wiring information. 20 Rockwell Automation Publication 1606-RM104A-EN-P - July 2020 1606-XLSBUFFER24 Buffer Module The 1606-XLSBUFFER24 buffer module is a supplementary device for DC 24V power supplies. It delivers power to bridge typical mains failures or extends the hold-up time after the AC power is turned off. When the power supply provides a sufficient voltage, the buffer module stores energy in the integrated electrolytic capacitors. When the mains voltage is lost, the stored energy is released to the DC-bus in a regulated process. The buffer module can be added in parallel to the load circuit at any given point and does not require any control wiring. One buffer module can deliver 20 A additional current and can be added in parallel to increase the output ampacity or the hold-up time. For longer hold-up times, the 1606-XLSBUFFER24 might also be an option. Series Operation Devices 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 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. When using the power supplies in series, use the standard mounting orientation. Leakage current, EMI, inrush current, and harmonics increase when using multiple devices. Figure 23 - Series operation Unit A AC DC + + Unit B AC DC Load + - Earth (see notes) Rockwell Automation Publication 1606-RM104A-EN-P - July 2020 21 The device can be used to build 1+1 redundant systems. Parallel Use for 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 thereby helps ensure that the output voltage is maintained. 1+1 redundancy allows ambient temperatures up to 70 °C (158 °F). Leakage current, EMI, inrush current, and harmonics increase when using multiple devices. Recommendations for building redundant power systems: • Use separate input fuses for each device. • Use separate mains systems for each device whenever it is possible. • Monitor the individual devices. Therefore, use the DC OK signal of the device. • Set the output voltages of all devices to the same value (± 100 mV) or leave it at the factory setting.

Such a phase-to-phase connection is allowed as long as the supplying voltage is below 240V +10%. Ensure that the wire, which is connected to the N-terminal, is appropriately fused. The maximum allowed voltage between a Phase and the PE must be below 300V AC. Figure 26 - Operation on two phases Power Supply L1 240V +10% max. AC L3 L2 Use In a Tightly Sealed Enclosure L N PE DC When the power supply is installed in a tightly sealed enclosure, the temperature inside the enclosure is 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. The temperature sensor inside the box is placed in the middle of the right side of the power supply with a distance of 1 cm (0.39 in.).

Frequently asked questions
The output voltage is DC 24V with an adjustment range of 24…28V. The factory setting is 24.1V, as mentioned in the 'Specifications' section of the viewed document.
The maximum output current is 20.0 A, but it can vary depending on the ambient temperature. At an ambient temperature below 55 °C (131 °F), it delivers 20.0 A. However, at 70 °C (158 °F), the output current derates to 12.5 A. The derating happens linearly between the temperatures of 55 °C and 70 °C.
Yes, this power supply has a hold-up time, which means it continues to provide regulated output voltage even when the input power is lost for a short period. The hold-up time depends on the output load, and it can be up to several seconds at no load. For example, at 24V and 10 A load, the typical hold-up time is 54 ms, and at 24V and 20 A load, it is 27 ms.
