Allen-Bradley 1746-P5 Power Supply SLC 500 Module

The Allen-Bradley 1746-P5 Power Supply is a DC power module for the SLC 500 modular chassis that provides the essential backplane power for the processor and I/O modules. It accepts a DC input in the 90–146 V range and delivers isolated 5 V DC at up to 5 A and 24 V DC at up to 0.96 A to the chassis, with a typical line power requirement of 85 VA. The 24 V user-power rail supports up to 200 mA with a voltage range of 18–30 V DC, and the supply offers 1800 V AC RMS isolation for 1 s (600 V AC RMS for 1 s on other paths). CPU hold-up time is specified as 20 ms at full load and 3000 ms no load; the unit uses a soldered fuse and carries UL and CE markings. It is part of the SLC 500 family’s 1746-P1 to -P7 series of modular power supplies.
