Description
The 1746-P4 power supply module, part of the SLC 500 series produced by Allen Bradley, delivers reliable and efficient performance in a range of applications. This module works with input line voltages of 85-132V AC and 170-265V AC, operating effectively across a frequency spectrum of 47 to 63 Hz.
Ideal for demanding scenarios, the module features a power requirement of 190 VA at 120 volts AC and 230 VA at 240 volts AC, accommodating the energy needs of connected devices. A notable specification includes a max inrush current of 45 amps which ensures stable operation during startup phases. The internal current capacity provides up to 10 amps for 5V DC and 2.88 amps for 24V DC. This flexibility makes it suitable for many control applications within various environments.
The unit contains a non-replaceable fuse for added protection, safeguarding the module from overcurrent situations. Permitted wiring configurations allow for two wires of up to #14 AWG per terminal, enabling straightforward integration into existing setups. The module is also rated for Class I Division 2 hazardous locations, emphasizing its suitability for environments where safety is paramount.

Features:
- 120/240V AC input power supply
- SLC™ 500 Modular Hardware
- Power LED status indication
- 10 A at 5 VDC and 2.88 A at 24 VDC
The 1746-P4 incorporates an internal power conversion circuit together with replaceable fuse protection for the incoming AC supply. A front-panel Power LED provides visual indication of normal power supply operation. The 1746-P4 distributes regulated power through the SLC 500 chassis backplane, eliminating the need for individual power connections to processors and I/O modules installed in the rack.
The 1746-P4 Allen-Bradley Power Supply Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

SLC 500 controllers continue to operate (hold-up) for a short period of time if theinput voltage to the power supply drops below the recommended operatingvoltage range. The controller continues to scan the user program and control I/Oduring this time. CPU hold-up for each power supply is shown on pages 14 and 16.SLC 500 controllers turn OFF (stop scanning and disable outputs) if input voltage tothe power supply is removed or drops below the recommended operating rangefor a period exceeding the CPU hold-up time. The controller resumes operationautomatically when the input voltage is restored to normal.If the input voltage to the 1746-P7 power supply falls into a range of 4 to 9V for aperiod exceeding the CPU hold-up time, the controller turns OFF and will not turnback ON until input voltage is increased to 11V dc.

Power Off: Disconnect all primary line power before starting.Align Guides: Align the circuit board edges of the 1746-P4 with the dedicated card guides found on the far left side of the SLC 500 chassis.
Slide In: Gently slide the power supply inward until the module sits completely flush against the chassis framework.
Secure Screws: Tighten the built-in chassis mounting screws on the top and bottom brackets to physically clamp the module in place.

Technical notes
The 1746-P4 is designed for installation in standard 1746 SLC modular chassis and operates within an ambient temperature range of 0 to 60°C (32 to 140°F). The module is intended for use in industrial automation environments and provides the regulated power required for reliable operation of the SLC 500 control platform. The 1746-P4 should be selected based on the total 5 VDC and 24 VDC current requirements of all modules installed in the chassis.
FAQs
-
What is the input voltage range for the 1746-P4?
+It operates on an auto-ranging or wide AC line voltage of 85 to 265V AC (47–63 Hz), covering standard 120V and 240V AC industrial requirements without manual configuration. -
Can I manually replace the internal fuse if it blows?
+No. Unlike the P1, P2, and P3 models, the 1746-P4 features a non-replaceable fuse. If an overcurrent or internal component failure causes the internal fuse to blow, the entire module must be repaired or replaced. -
What is the 24V DC User Power terminal used for?
+The module provides up to 1 Amp of 24V DC user power directly on its external terminals. This output is typically utilized to power external field devices, such as sensors, switches, or low-draw instrumentation loops. -
What are the input voltage and frequency requirements?
+It accepts an auto-ranging alternating current (AC) input of 85–265V AC at a frequency range of 47–63 Hz
