Technical Specifications

Information About 1746-P3

The Allen-Bradley 1746-P3 is a rack-mount power supply designed for the SLC 500 series. It operates at a nominal input supply range of 19.2 - 28.8 VDC, providing reliable power to the connected system components. With an internal current capacity of 3.6 A at 5VDC and 0.87 A at 24VDC, it ensures stable and consistent power delivery to the system.

Primarily, the 1746-P3 power supply is responsible for supplying power to the backplane, which serves to energize the SLC 500 modules installed within the chassis. This ensures proper functionality and operation of the connected modules, enabling the overall system to perform its intended tasks effectively.

The power supply's specifications include a hold-up time of 5 ms under full load conditions and 1000 ms under no-load conditions, ensuring continuous power availability even during transient events. It also features inrush current protection rated at 20 A, safeguarding the system against excessive current spikes during power-up sequences.

With a compact and efficient design, the Allen-Bradley 1746-P3 power supply is suitable for rack-mount applications where space is limited. Its dimensions measure 5.5 x 2.9 x 5.7 inches, making it compatible with standard rack-mount configurations.

The power supply complies with a wide ambient operating temperature range of 0 to 60 degrees Celsius, ensuring reliable performance even in challenging environmental conditions. Additionally, it offers a high degree of isolation, with an isolation voltage rating of 600V AC RMS for 1 second, providing enhanced safety and protection for the connected equipment.

Fuse protection is integrated into the design, with the recommended fuse being the 1746-F3 or an equivalent alternative. This further enhances the safety and reliability of the power supply unit.
