Allen-Bradley 1606-XL240E-3 Power Supply

1606-XL240E-3 240W Three-Phase PSU

Product Introduction

The 1606-XL240E-3 is a legacy industrial power supply from the Allen-Bradley Bulletin 1606-XL series. It delivers a reliable 240 watts of output power for control systems and automation equipment. Specifically, this unit accepts a three-phase AC input and provides a stabilized 24V DC output. However, buyers should note that Rockwell Automation officially discontinued this model in 2017. Therefore, current availability is limited to remaining stock or the secondary market. For new designs, the recommended direct replacement is the 1606-XLE240E-3.

Technical Specifications

The electrical performance of the 1606-XL240E-3 centers on its robust three-phase input and clean 24V output. It operates from a wide range of input voltages, making it suitable for various industrial power grids. Additionally, the unit supports a DC input option for flexible deployment.

• Input Voltage: The unit accepts a three-phase AC input of 400...500 V. Moreover, it can operate on a DC input range of 450...820 V.

• Output Voltage: The output is adjustable from 24...28 V DC, with a factory preset of 24.5 V.

• Output Current: It provides 10 A at 24 V, which derates to 8.6 A at 28 V.

• Rated Power: The continuous output power is rated at 240 W.

• Efficiency: Efficiency is rated up to 91.9%, minimizing heat generation inside the cabinet.

• Ripple and Noise: Output ripple is kept low at a maximum of 30 mVpp, ensuring stable power for sensitive loads.

Mechanical and Environmental Parameters

The physical construction of this power supply is designed for space-saving installation in industrial enclosures. Furthermore, its compact footprint suits crowded control cabinets.

• Dimensions: The unit measures 124 × 89 × 117 mm (H × W × D). Its compact width allows for efficient use of DIN rail space.

• Weight: It weighs approximately 980 g.

• Operating Temperature: The operating range is 0...+70 °C. Furthermore, derating is required above 60 °C to ensure reliability.

• Protection Rating: The unit carries an IP20 rating, which is standard for open-frame DIN rail devices.

• Mounting: It is designed for standard DIN rail mounting, facilitating quick installation and replacement.

Installation Guide

Proper installation ensures the longevity and safe operation of the 1606-XL240E-3. First, verify that the incoming three-phase power is disconnected before wiring. The unit features screw connection terminals for secure wiring of input and output cables. Next, mount the device vertically on a DIN rail to allow for convection cooling. It is crucial to provide adequate clearance above and below the unit for airflow. Besides, ensure the protective earth connection is made securely to the input block terminal, not to the housing screws, to prevent electrical hazards. Finally, check the output voltage setting before connecting sensitive loads.
