PE has the same meaning as the symbol. The symbol for Protective Earth. Earth, Ground AC 230V 230V AC 50 Hz versus 60 Hz nom typ — (alone in table cell) This document uses the term “earth” which is the same as the U.S. term “ground”. A value that is displayed with the AC or DC before the value represents a nominal voltage with standard tolerances (usually ±15%) included. For example, DC 12V describes a 12V battery disregarding whether it is full (13.7V) or flat (10V). A value with the unit (V AC) at the end is a momentary value without any additional tolerances included. As long as not otherwise stated, AC 100V and AC 230V parameters are valid at 50 Hz mains frequency. AC 120V parameters are valid for 60 Hz mains frequency. Indicates a nominal value. Indicates a typical value. A dash alone in a table cell indicates that there is no information to be included in that cell. All values in this document are typical values under the following conditions unless otherwise noted: 230V AC 50 Hz input voltage, 24V 3.8 A output load, 25 °C (77 °F) ambient temperature, and after a 5 minutes run-in time. Product Overview Figure 1 - 1606-XLB90EH Power Supply The 1606-XLB90EH is part of a series of compact industrial grade DIN rail power supplies that focus on the essential features needed in present day industrial applications.

The mechanically robust housing is made of a high-grade, reinforced molded material, which permits the units to be used in surrounding temperatures up to 70 °C (158 °F). The 1606-XLB90EH is equipped with push-in terminals, which are optimized for automated wiring. The unit is designed as Class of Protection II unit and fulfills the safety and electromagnetic compatibility (EMC) requirements without an input PE connection. This saves wiring costs.

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. Max Output voltage < 14V DC, see Figure 10 (1) At heavy overloads (when output voltage falls below 14V), the power supply delivers continuous output current for 20 ms. After this, the output is switched off for approximately 160 ms 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 operates normally. See Figure 11.

The lifetime expectancy of the built-in electrolytic capacitors determines the lifetime expectancy of the power supply. 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.

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 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. For these types of units, the Mean Time To Failure (MTTF) value is the same as the MTBF value.

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 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 for resistive loads: Figure 25 - 7.6 A Peak Current for 50 ms, Typ (2x the nominal current) Output Voltage 24V Figure 26 - 19 A Peak Current for 5 ms, Typ (5x the nominal current) 24V Output Voltage 16.5V 19 A 9.5V 7.6 A Output Current 0A Output Current 0A 10 ms/DIV Attribute Peak current voltage dips 1 ms/DIV Values Notes Typically dips from 24V to 16.5V At 7.6 A for 50 ms and resistive load Typically dips from 24V to 13.5V At 19 A for 2 ms and resistive load Typically dips from 24V to 9.5V At 19 A for 5 ms and resistive load Rockwell Automation Publication 1606-RM120A-EN-P - July 2020 19 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. Do not use power supplies in series in mounting orientations other than the standard mounting orientation. Leakage current, EMI, inrush current, and harmonics increase when using multiple devices. Figure 27 - Series Operation Unit A Input + Output + Unit B Load Input + - - Output Parallel Use for 1+1 Redundancy Devices can be paralleled for 1+1 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, which helps to ensure that the output voltage can be maintained. A means to report a defective or non-functional power supply is essential for redundant systems. This power supply does not incorporate such means of reporting. So if you use it for 1+1 redundancy, use it with a redundancy module that monitors and reports insufficient input voltage. Alternatively, you could use a different model of power supply that has a DC OK signal included. With a DC OK signal, you would not need the redundancy module to have the monitoring and reporting feature. 20 Rockwell Automation Publication 1606-RM120A-EN-P - July 2020 Operation on Two Phases 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%. Ensure that the wire, which is connected to the N-terminal, is appropriately fused. Figure 28 - Operation on Two Phases Power Supply L1 240V +10% max AC L3 L N DC L2 Use In a Tightly Sealed Enclosure When the device 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 device. In the following test setup, the device is placed in the middle of the box, no other heat-producing items are inside the box. The load is placed outside 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.). The following measurement results can be used as a reference to estimate the temperature rise inside the enclosure.

Frequently asked questions
The maximum output current is 3.8 A at ambient temperatures below 60 °C (140 °F).
Yes, but the capacitive load should not be larger than 5500 μF with 3.8 A or 7000 μF with 1.9 A additional current load.
The hold-up time is the time during which the output voltage remains within specification after the loss of input power. It depends on the output load and can be up to 25 ms with a 3.8 A load.
The power supply has overload protection and will switch off automatically if the output voltage drops below 14V DC. It will then attempt to restart after approximately 160 ms.
