Allen-Bradley 1606-XL720E-3 Power Supply 720W

Allen-Bradley 1606-XL720E-3 24V 30A PSU

Product Introduction

The 1606-XL720E-3 belongs to the Bulletin 1606-XL switched-mode power supply family from Allen-Bradley. This three-phase input variant provides a regulated 24V DC output with a 30A current rating, delivering 720W of continuous power. Engineers commonly use this unit in machine control cabinets, process automation panels, and material handling systems where reliable 24V rails are essential.

Technical Specifications

The 1606-XL720E-3 accepts a three-phase AC input range of 340 to 576 V. Two-phase operation is also permitted, which adds flexibility during commissioning. At 24V nominal, the unit supplies 30 A continuously; at 28V it delivers 26 A. Rated power sits at 720 W, and efficiency reaches up to 92.5% under typical load conditions.

Output voltage is adjustable, and the front panel includes a DC OK status indicator. Furthermore, the supply carries overload and short-circuit protection as standard. Approvals include UL 60950-1, cUL, and CE marking under the official Bulletin 1606 series standard.

Communication interfaces are absent by design. Specifically, this is a pure power conversion device with no built-in ports and no supported protocols.

Mechanical and Environmental Parameters

Dimensions measure 124 mm (H) × 240 mm (W) × 112 mm (D), and the unit weighs 2.0 kg. Housing is an open-frame DIN rail construction rated IP20. The operating temperature range spans -10 to +70 °C, while storage tolerates -25 to +85 °C. Relative humidity figures are not published for this legacy series.

Installation Guide

First, mount the 1606-XL720E-3 on a standard 35 mm DIN rail inside a protective enclosure. Next, connect the three-phase input wiring to the designated terminals and verify the voltage falls within 340 to 576 V AC. Then set the adjustable output to the required level using the front potentiometer. Meanwhile, confirm the DC OK LED illuminates green after power-up. Finally, tighten all terminal screws to the torque stated in the datasheet and check for short circuits before loading the supply.

FAQ

Q1: Is the 1606-XL720E-3 still available?
A: Rockwell discontinued this model on April 04, 2018. The direct replacement is the 1606-XLE960DX-3N.

Q2: Can this supply run on two phases?
A: Yes. Official ODVA conformance listing permits two-phase operation at reduced output.

Q3: What output current does it provide at 28V?
A: The unit delivers 26 A at 28V, compared with 30 A at 24V nominal.

Q4: Does it include a communication port?
A: No. The 1606-XL720E-3 has no communication interface or supported protocol.

Q5: What is the IP rating?
A: The open-frame DIN rail housing carries an IP20 protection rating.
