Allen-Bradley 1606-XLP90E-2 24V DC Supply

Allen-Bradley 1606-XLP90E-2 Compact Power Supply

Product Introduction

The 1606-XLP90E-2 belongs to the Allen-Bradley Bulletin 1606-XL compact series of switched-mode power supplies. This two-phase model accepts 380-480V AC input and produces a regulated 24V DC output rated at 90W. Machine builders often choose it for panels fed directly from higher-voltage distribution. Moreover, the NEC Class 2 rating limits output energy, which simplifies field wiring in many installations. The 1606-XLP90E-2 fits narrow DIN rail spaces thanks to its compact housing.

Technical Specifications

The output provides 24V DC nominal, adjustable from 24 to 28V DC. At 24V, the unit delivers 3.75A continuously, giving a rated power of 90W. Efficiency is 89.5 percent typical, which keeps waste heat modest. Hold-up time exceeds 93 ms typical at 480V AC, supporting brief supply dips. Additionally, spring clamp terminals speed up wiring and resist vibration.

Input voltage is 380-480V AC two-phase nominal, with an operational range of 323 to 552V AC. This variant suits equipment connected across two phases of a 400V or 480V system. Furthermore, the NEC Class 2 classification caps output power for safety. No power boost function is included, so loads should stay within the continuous rating. The unit has no communication ports or protocols.

Mechanical and Environmental Parameters

The housing measures 75 mm high, 73 mm wide, and 103 mm deep. Unit weight is 0.36 kg. Mounting supports both DIN rail and wall installation. The protection rating is IP20, so the unit belongs inside an enclosure. Operating temperature starts at -10 °C, while storage temperature starts at -40 °C. Relative humidity stays below 95 percent non-condensing. Approvals include UL 60950-1, cUL, and CE marking per the Bulletin 1606 standard.

Installation Guide

First, confirm the two-phase supply falls within the 323 to 552V AC range. Next, snap the unit onto a DIN rail or fix it to a wall with screws. Then, connect the two input phases and the output wires to the spring clamp terminals. After that, verify output polarity before energizing downstream devices. Finally, adjust the trim between 24 and 28V DC as required. Keep the housing clear for airflow during operation.
