Mean Well S-100F-24 24VDC/4.5A Power Supply

The Mean Well S-100F-24 is a 108W single-output switching power supply delivering 24VDC at 4.5A for industrial and electronic applications. This compact, lightweight chassis-mount unit combines dual-range selectable AC input (88–132VAC / 176–264VAC) with comprehensive protection circuitry, including soft-start limiting, overload hiccup shutdown with auto-recovery, and integrated EMI filtration. Output voltage is adjustable ±10%, with ±0.5% line and load regulation, ripple noise of 150mVp-p, and 83% efficiency at full load.
