Allen-Bradley 1606-XL960E-3 960W Supply

Allen-Bradley 1606-XL960E-3 Three-Phase Power Supply

Product Introduction

The 1606-XL960E-3 belongs to the Allen-Bradley Bulletin 1606-XL family of switched-mode power supplies. This three-phase model delivers a 960W output at 24V DC and 40A for heavy industrial loads. Large panels use it to feed PLC racks, drive logic, and distributed I/O clusters. However, Rockwell has announced end of life for this unit, with the end of sale on 30 October 2017. The listed direct replacement is the 1606-XLE960DX-3N. Therefore, the 1606-XL960E-3 now serves mainly as a spare-part or legacy-maintenance item.

Technical Specifications

The output spans 24 to 28V DC with a continuous current of 40A at 24V. Rated power reaches 960W. Efficiency climbs to 92.6 percent, which limits heat generation in dense cabinets. Ripple and noise stay at 50 mVpp maximum for clean DC delivery. Additionally, the input accepts three-phase 400 to 500V AC with a ±15 percent tolerance. This wide window tolerates typical plant voltage drift.

The unit has no communication ports or protocols. Consequently, monitoring relies on external devices rather than internal diagnostics. DIN rail mounting keeps installation quick and consistent with other Bulletin 1606 units. For new designs, engineers should specify the replacement model to secure long-term support.

Mechanical and Environmental Parameters

The housing measures 124 mm high, 275 mm wide, and 117 mm deep. Weight is 3.3 kg, so two people should handle installation in tight cabinets. Operating temperature spans 0 to +70 °C with derating above 60 °C. Storage temperature spans -25 to +85 °C. The manufacturer does not publish a relative humidity figure for this model. Protection rating is IP20 for open-frame DIN rail construction. Approvals include UL 60950-1, cUL, and CE marking.

Installation Guide

First, confirm the three-phase supply sits within 400 to 500V AC at ±15 percent. Next, mount the unit on a sturdy DIN rail and secure the end stops. Then, connect the three input phases and the output wires with correct torque. After that, check output polarity before energizing downstream loads. Finally, verify airflow around the wide housing and apply derating above 60 °C. For new builds, consult Rockwell about the 1606-XLE960DX-3N replacement path.
