Allen-Bradley 1606-XL180B 12V 180W Power Supply

Allen-Bradley 1606-XL180B 12V DC Power Supply

Product Introduction

The 1606-XL180B is a switched-mode power supply from the Allen-Bradley Bulletin 1606-XL series. This unit converts single-phase AC 85–264 V input into a regulated 12 V DC output. It delivers 180 W of rated power with 15 A output current at 12 V. Engineers use this model in control panels, machine tools, and legacy automation systems that run on 12 V DC logic.

The 1606-XL180B carries UL 60950-1, cUL, and CE approvals. Its DIN rail mount design suits open-frame cabinet installation. The adjustable output spans 12 V to 15 V, which helps compensate for cable voltage drop. Moreover, overload and short-circuit protection safeguard the load and wiring. Rockwell discontinued this model on October 30, 2017, and the 1606-XLS180B serves as the direct replacement.

Technical Specifications

The 1606-XL180B accepts AC 85–264 V single-phase nominal input, covering worldwide mains voltages. Output voltage is preset at DC 12 V ±0.5% and adjustable from 12 V to 15 V. Output current reaches 15 A at 12 V and 12 A at 15 V, rated continuous at ambient 0–60 °C. Rated power is 180 W. A DC OK status signal reports output health to the control system.

Overload and short-circuit protection circuits trip automatically under fault conditions. Additionally, the unit has no communication interface or protocol, since it is a pure power conversion device. This simplicity keeps wiring clean and reduces failure points in legacy cabinets.

Mechanical and Environmental Parameters

The housing measures 124 mm high × 120 mm wide × 102 mm deep. It weighs 0.98 kg (980 g), so the DIN rail must support moderate load. Protection rating is IP20, matching open-frame DIN rail construction. Operating temperature spans -10 to +70 °C. Storage temperature ranges from -40 to +85 °C. Relative humidity is not published for this legacy XL series model.

Installation Guide

First, mount the 1606-XL180B on a standard 35 mm DIN rail inside the enclosure. Next, connect the single-phase AC input to the L and N terminals. Then wire the 12 V DC output to the load, checking polarity carefully. After that, measure the output with a multimeter and adjust the potentiometer if needed. The adjustment range is 12 V to 15 V.

Finally, wire the DC OK contact to a monitoring input if the system requires status feedback. Keep clearance above and below the unit for airflow. Because this model is discontinued, confirm the replacement 1606-XLS180B for new designs.

FAQ

Q1: What is the output rating of the 1606-XL180B?
A: The unit provides 12 V DC at 15 A, or 180 W rated power. At 15 V the current drops to 12 A.

Q2: Is the output voltage adjustable?
A: Yes. A potentiometer adjusts the output from 12 V to 15 V DC. The factory preset is 12 V ±0.5%.

Q3: Is the 1606-XL180B still in production?
A: No. Rockwell discontinued it on October 30, 2017. The 1606-XLS180B is the direct replacement for new projects.

Q4: Does this power supply offer communication?
A: No. It has no communication port or protocol. It does provide a DC OK status contact for basic monitoring.

Q5: What input voltage does the unit accept?
A: It accepts AC 85–264 V single-phase nominal. This range covers standard industrial mains worldwide.
