Allen-Bradley S-100-5 Power Supply

The S-100-5 AC-DC switching power supply delivers a regulated 5 V DC output at up to 20 A (100 W) from 110–220 VAC input, making it suitable for industrial control panels and power distribution. Built as a metal-enclosed, panel- or chassis-mounted unit from a generic/OEM manufacturer, it uses free-air convection cooling and includes overload, overvoltage, and short-circuit protections. Its output voltage can be adjusted roughly 4.75–5.5 V DC, with typical ripple and noise around 100 mVp-p and efficiency around 80–86% depending on variant. Common applications include powering PLC modules, sensors, LEDs, CCTV systems, embedded electronics, and other control electronics in industrial automation environments.
