Allen-Bradley 1746-P2 SLC 500 Chassis Mount Power Supply Module

Product Overview

The 1746-P2 functions as a high-capacity power supply module for the Allen-Bradley SLC 500 series controller platform. This module mounts directly to the left side of an SLC 500 chassis, providing regulated DC power to the backplane to drive processors and I/O modules. We supply this unit as 100% Brand New in its original factory packaging, ensuring maximum operational life and circuit protection for your legacy or active automation systems.

Technical Specifications

The 1746-P2 delivers high-amperage performance to support dense I/O configurations:

• Input Voltage: 120V/240V AC (Selectable)

• Current Output (5V DC): 5 Amps

• Current Output (24V DC): 0.96 Amps

• Mounting Type: Chassis/Rack Mounting (Left Side)

• Operating Temperature: 0°C to 60°C (32°F to 140°F)

• Storage Temperature: -40°C to 85°C (-40°F to 185°F)

• Relative Humidity: 95% (Maximum)

• Weight: 1.38 lbs (0.62 kg)

Engineering Advantages

• High-Density Power Delivery: The 5 Amp rating at 5V DC allows engineers to populate larger 10-slot and 13-slot SLC chassis with power-hungry analog and specialty modules without voltage drops.

• Dual-Voltage Versatility: A jumper or switch selection enables the module to accept either 120V or 240V AC input. This flexibility simplifies spare parts inventory for global facilities operating on different power grids.

• Thermal Resilience: The hardware maintains stable voltage regulation up to 60°C. This wide operating window solves overheating issues common in tightly packed control cabinets with limited airflow.

• Integrated Backplane Protection: Advanced internal circuitry filters line noise and protects the SLC backplane from power surges. This design effectively prevents catastrophic damage to expensive CPU and communication modules during electrical transients.

FAQs

• Is the 1746-P2 provided as a brand new original unit?

  Yes. We supply this product as 100% Brand New original stock. It arrives with factory-original seals to guarantee it meets Allen-Bradley’s stringent quality and safety standards.

• Can the 1746-P2 replace a 1746-P1 power supply?

  Yes, the 1746-P2 serves as a higher-capacity upgrade for the 1746-P1. While the P1 provides only 2 Amps at 5V DC, the P2 provides 5 Amps. Always verify that your chassis physical dimensions and total system current draw align with the P2 specifications.

• How do I configure the input voltage for 240V AC?

  You must set the input voltage jumper located on the module before applying power. Selecting the incorrect voltage range can result in immediate hardware failure; always consult the wiring diagram on the side of the 1746-P2 housing during installation.

• Does this module require a specific slot in the SLC 500 chassis?

  The 1746-P2 occupies a dedicated space on the extreme left side of the SLC 500 chassis. It does not consume a standard I/O slot, allowing you to utilize the full capacity of your 4, 7, 10, or 13-slot rack for modules.
