Allen-Bradley 1746-P2 Power Supply

Allen-Bradley 1746-P2 Power Supply is a rack-mount power module for the SLC 500 backplane that delivers a stable 24 VDC supply to the CPU, I/O, and field devices in a standard SLC rack. It accepts AC input from 120/240 VAC at 50/60 Hz (47–63 Hz tolerance) and can source up to 5 A on its 24 VDC output, making it a higher-current option among the 1746 power supplies. Designed for industrial environments, the P2 tolerates ambient temperatures from 0 to 60°C (32–140°F) and is intended for use with Allen-Bradley SLC 500 systems, where a reliable 24 V rail is essential for CPU modules and I/O backplanes. When selecting a spare or replacement, verify rack compatibility with 1746 power supplies and ensure the input voltage setting matches your facility supply; this legacy component continues to support long-running SLC 500 installations requiring dependable 24 VDC power.
