The Allen-Bradley 1746-P2 is a robust modular power supply designed for the SLC 500 automation system. With an input voltage range of 85-132V or 170-265V AC at frequencies between 47-63 Hz, this power supply ensures flexibility and reliability. It features a 5A internal current capacity at 5V and 0.96A at 24V, with overcurrent protection up to 15A and an inrush current maximum of 20A. The unit offers a typical line power requirement of 180 VA and provides crucial isolation of 1800V AC RMS for 1 second between input terminals and the backplane. Safety is prioritized with a built-in fuse, designed for fire hazard protection in short circuit conditions, while the open-type enclosure requires it to be installed in the leftmost slot of the 1746 chassis, allowing safe and efficient integration into your control system without affecting the overall slot count.
