Allen-Bradley 1606-XLP50B 24V 50W Power Supply

Allen-Bradley 1606-XLP50B Compact Power Supply

Product Introduction

The 1606-XLP50B belongs to the Allen-Bradley Bulletin 1606-XL series of compact power supplies. This model converts AC 100–240 V or DC 110–300 V input into a stable 24 V DC output. It delivers 50 W of rated power with 2.1 A nominal output current. Engineers choose this unit for machine control cabinets, process skids, and small automation panels where space is limited.

The power supply carries UL 60950-1, cUL, and CE approvals. Its slim 45 mm width saves valuable DIN rail space. Meanwhile, spring terminals speed up wiring and reduce installation time. A DC OK relay contact provides a simple status signal to the control system.

Technical Specifications

The 1606-XLP50B offers a nominal 24 V DC output that users can adjust from 24 V to 28 V. Output current ranges from 2.1 A to 1.8 A across the adjustment band. Rated power stays at 50 W. Typical efficiency reaches 89.0%, which lowers heat buildup inside the cabinet. Ripple and noise remain below 50 mVpp maximum, protecting sensitive loads.

Input voltage accepts AC 100–240 V nominal and DC 110–300 V. This dual input capability suits both AC mains and DC bus applications. Additionally, the unit includes an adjustable output potentiometer for fine voltage tuning. The DC OK relay contact reports output status to PLCs or alarm circuits.

Mechanical and Environmental Parameters

The housing measures 75 mm high × 45 mm wide × 91 mm deep. It weighs just 240 g, so DIN rail loading stays light. Protection rating is IP20, suitable for enclosure mounting. Operating temperature spans -10 to +70 °C. The compact metal-free housing fits standard 35 mm DIN rail.

Storage temperature and relative humidity values are not published in Bulletin 1606-TD002H. Therefore, follow general industrial storage practice for these parameters. The spring terminal design accepts solid and stranded wires without screw tightening.

Installation Guide

First, snap the 1606-XLP50B onto a 35 mm DIN rail inside the control cabinet. Next, connect input wires to the L and N terminals for AC supply, or to the positive and negative terminals for DC input. Then wire the 24 V output to the load circuit. The spring terminals open with a small screwdriver, and the wire inserts directly.

After wiring, set the output voltage using the front potentiometer if adjustment is needed. The factory setting is 24 V DC. Finally, connect the DC OK relay contact to your monitoring circuit. Mount the unit vertically with clearance above and below for convection cooling. Do not block the ventilation slots.

FAQ

Q1: What input voltages does the 1606-XLP50B accept?
A: The unit accepts AC 100–240 V nominal and DC 110–300 V. This dual-range input covers most industrial supply systems worldwide.

Q2: Can I adjust the output voltage on this power supply?
A: Yes. A front-mounted potentiometer lets you set the output from 24 V to 28 V DC. The factory default is 24 V.

Q3: Does the 1606-XLP50B include a status signal output?
A: Yes. A DC OK relay contact provides a dry contact signal. You can wire it to a PLC input or alarm circuit for output monitoring.

Q4: What is the operating temperature range?
A: The supply operates from -10 to +70 °C. Install it with adequate ventilation inside the enclosure for best performance.

Q5: How does the unit mount inside a cabinet?
A: It snaps onto standard 35 mm DIN rail. Spring terminals handle the wiring, so no screw tightening is required.
