  • Product typeAT
  • Stable 24 V output with ±1 % regulation for sensitive security gear
  • 4 W continuous power from 86 % efficient switching design
  • Wide 85–264 V AC input with selectable range suits global installations
  • Low 200 mV ripple and ±0.5 % load regulation protect connected devices
  • Compact copper-coil transformer enables safe, simple wiring in industrial cabinets

24 V 50.4 W industrial power supply

The myVolts S-50-24 delivers a regulated 24 V DC output at up to 2.1 A for 50.4 W total power. It is built for security monitoring, PLC control systems, industrial automation and similar fixed installations that need a compact, reliable source. The unit weighs little and fits tight enclosures without special mounting hardware.

AC input range and output limits

A rear switch selects between 85–132 V AC and 170–264 V AC inputs at 47–63 Hz, also accepting 240–370 V DC. Efficiency reaches 86 % while ripple and noise stay within 200 mV peak-to-peak. Line and load regulation are each held to ±0.5 %, and the output voltage can be trimmed by ±10 % from the nominal 24 V. The supply is not suited for loads that exceed 2.1 A or for equipment requiring a different DC voltage.

Wiring and common installation issues

Spring or screw terminals accept simple two-wire DC connections, and the copper-coil transformer keeps the chassis cool during continuous operation. Installers must set the input-voltage selector to match the local mains before applying power; an incorrect setting will damage the unit. The cold-start inrush reaches 45 A at 230 V AC, so the upstream breaker or fuse must tolerate that peak. Leakage current remains below 2 mA at 240 V AC, meeting typical industrial safety limits.

Questions about this item

How do I pick the right input voltage setting for my mains supply?

Use the selector switch to choose 85-132VAC for 115VAC regions or 170-264VAC for 230VAC regions; the unit accepts 47-63Hz and 240-370VDC.

What does the 50.4W rating mean for my 24V security gear?

It delivers up to 2.1A at 24V, so cameras or PLCs drawing 50.4W or less will run within the ±1% voltage tolerance and 200mVp-p ripple.

What limits does the AC input range place on installation?

The switch-selectable 85-132VAC or 170-264VAC range covers most global mains, with 1.1A draw at 115VAC and 0.65A at 230VAC.
