Product Introduction
The 1606-XLE80E belongs to the Allen-Bradley Bulletin 1606-XL Essential family of switched-mode power supplies. This model converts a wide-range single-phase AC input into a regulated 24 V DC rail for industrial control circuits. Specifically, it supplies 3.3 A continuously and reaches a rated power of 80 W. Moreover, NEC Class 2 protection limits output energy, which simplifies field wiring in many installations. A DC OK relay contact reports output status, and screw terminals keep wiring familiar for maintenance teams. The product remains active on the official Rockwell product page, so new builds and spare-part planning can both rely on it.
Technical Specifications
The electrical design of the 1606-XLE80E emphasizes input flexibility and safe, limited-energy output. Input voltage accepts 100–240 V AC nominal, which covers common single-phase mains worldwide. The output is 24 V DC nominal and adjustable across 24–28 V DC. At 24 V, the unit delivers 3.3 A maximum, giving the full 80 W rating. Typical efficiency reaches 89.8%, which keeps heat generation modest inside tight enclosures.
Class 2 Protection and Boost Behavior
A key feature is NEC Class 2 classification, which caps output energy and supports simpler wiring rules in many regions. Additionally, an NTC inrush current limiter reduces startup surge on the mains feed. A dynamic 120% power boost is available up to +45 °C. Therefore, the supply can briefly push about 4 A for motor starts or capacitive loads. Meanwhile, the DC OK relay contact reports output status to a PLC or indicator lamp. The unit has no communication ports and no protocols; the relay contact is the only signal path.
Mechanical and Environmental Parameters
The body measures 124 mm high, 32 mm wide, and 102 mm deep, and it weighs 0.43 kg. The narrow 32 mm width saves valuable DIN rail space in dense panels. DIN rail and wall mounting are both supported, which adds layout flexibility. The open-frame design carries an IP20 rating, so it belongs inside a protective enclosure. Operating temperature spans -25 to +70 °C, and relative humidity runs 5 to 95%. The published storage lower bound is -25 °C; the full storage range is not listed numerically. Approvals include UL 60950-1, cUL, and CE marking.
Thermal and Derating Notes
Moderate efficiency still limits internal heat, yet output power derates at elevated ambient temperatures. Consequently, installers should leave clearance above and below the unit for convection. Wall mounting can help when panel airflow is limited. In addition, the 120% boost applies only up to +45 °C. Keep the DC OK relay wiring separated from power cables to avoid false signals in noisy panels.
Installation Guide
First, confirm that the mains supply falls within 100–240 V AC nominal. Next, mount the 1606-XLE80E on a DIN rail or a flat wall surface inside the enclosure. After that, connect input, output, and relay wires using the screw terminals, observing polarity. Then set the output voltage within 24–28 V DC using the front adjustment. Finally, apply power and check the DC OK contact state. Leave ventilation clearance, and route signal wires away from noisy power lines throughout the panel.

FAQ
Q1: What does NEC Class 2 mean for the 1606-XLE80E?
NEC Class 2 limits output energy under defined voltage and current thresholds. This classification can simplify wiring rules and reduce protection requirements for connected loads in many installations.
Q2: How much reserve current does the 120% boost provide?
The boost raises output to about 4 A for short peaks. It is available up to +45 °C ambient. Use it for motor starts or capacitive loads, not for continuous operation.
Q3: Does the 1606-XLE80E support communication protocols?
No. It has no communication ports and no protocols. The DC OK relay contact is the only status output, and it works as a dry signal for PLCs or lamps.
Q4: Can I adjust the output above 24 V?
Yes. The output is adjustable from 24 to 28 V DC. At higher voltage settings, the maximum current stays capped, so available wattage remains within the 80 W rating.
Q5: What mounting options does this supply offer?
It supports both DIN rail and wall mounting. The narrow 32 mm body suits dense panels, while wall mounting helps when airflow or depth favors a flat position.
