Allen-Bradley · HMIs & Displays

Description The Allen-Bradley 1746-P1 is an SLC 500 power supply module that provides regulated backplane power to support SLC controller systems. It operates with an input range of 85–132 or 170–265 VAC at 47–63 Hz, delivering 2 A at 5 VDC and 0.46 A at 24 VDC. Compact and reliable, it is designed for installation in 1746 chassis to power processors and I/O modules.     Technical Specifications  Condition New/Never Used Surplus Manufacturer Rockwell Automation Brand Allen-Bradley Category Industrial Automation Part Number 1746-P1 Subcategory Power Supply Modules Series SLC 500 Module Type Rack Power Supply Input Voltage 85–132 VAC (50 Hz), 170–265 VAC (60 Hz) Input Power 42 W Power Rating 135 VA Frequency 47–63 Hz Inrush Current 20 A Backplane Current (5 VDC) 2 A Backplane Current (24 VDC) 0.46 A Output Voltage Range 18–30 VDC User Power Output 200 mA at 18–30 VDC Fuse Protection 1746-F1 or equivalent Mounting Type Rack-mounted (leftmost chassis position) Standards GOST, KC, Marine Status Indicators LED status display Operating Temperature 0–60 °C Dimensions 5.51 in H × 2.56 in W × 5.7 in D Weight 1.23 lb       Information About 1746-P1 The 1746-P1 is part of the Allen-Bradley SLC 500 product family, designed to deliver consistent power for controllers and expansion modules in industrial automation. Installed at the leftmost position of the 1746 chassis, this module supplies both the backplane and user power requirements of the system. It features a CPU hold-up time of 20 ms at full load and up to 3000 ms at no load, allowing the system to continue scanning logic briefly during power fluctuations. With built-in fuse protection and an additional user-supplied overcurrent safeguard rated at 15 A, the 1746-P1 ensures reliable operation and protection in demanding environments. Key Features Backplane Power Supply: Provides 2 A at 5 VDC and 0.46 A at 24 VDC to support SLC 500 controllers and modules. Wide Input Range: Operates on 85–132 VAC or 170–265 VAC at 47–63 Hz. CPU Hold-Up Time: Maintains controller operation for 20 ms at full load and up to 3000 ms at no load during voltage dips. User Power Output: Supplies 18–30 VDC at 200 mA for external devices. Fuse Protection: Equipped with replaceable fuse (1746-F1) to protect against fire hazards from short circuits. Overcurrent Safeguard: Supports user-supplied 15 A protection for added safety. Chassis Compatibility: Installs in the leftmost slot of 1746 chassis for main, expansion, or remote I/O racks. Compact Design: Measures 5.5 × 2.3 × 5.7 inches and weighs approximately 2 lbs. The 1746-P1 delivers the reliability and precision required for powering Allen-Bradley SLC 500 controllers and I/O modules in industrial automation environments.
