Industrial 24V AT Supply

This myVolts S-100-24 unit delivers 24 volts at 4.2 amps for 100 watts of continuous power. It accepts a universal AC input from 100 to 240 volts and provides DC output through L, N, GND and V terminals with an adjustable voltage tap. The aluminium alloy enclosure relies on natural convection cooling. It suits industrial automation, LED displays, CCTV, radio equipment, 3D printers and similar 24 V DC loads.

Wiring and Mounting

Installation requires connecting live and neutral to the AC input terminals and securing the DC load to the GND and V outputs; the ADJ terminal allows fine voltage trimming. No forced-air cooling is present, so the unit must be mounted with free airflow around its aluminium case. The screw-terminal block demands correct polarity — reversed DC connections will trigger the protection circuit. Operating temperature range is 0 to 40 °C with up to 95 % non-condensing humidity.

Pre-Purchase Checks

Verify that your equipment requires a 24 V DC supply rated at or below 4.2 A and can tolerate the AT form factor. Confirm the available mounting space accommodates the approximate 85 x 58 x 33 mm footprint and that natural convection is sufficient for the installation environment. Ensure the AC mains voltage at the site falls within the 100 to 240 V range and that local regulations accept CCC, FCC and CE compliance marks.

Questions about this item

How can I confirm the S-100-24 is delivering a stable 24 V after installation?

Measure the DC output with a multimeter; it should read close to 24 V with minimal ripple, and the unit should run without triggering its short-circuit, overload or over-voltage protections.

What comes in the box with the S-100-24 and what must I source separately?

The supply itself is included; you must provide an AC mains cable for the L and N terminals and your own DC wiring for the V+ and GND outputs.

Which model from the comparison table should I choose if I need 4.2 A at 24 V?

Select the S-100-24, rated at 100 W and 4.2 A; the S-48-24 and S-60-24 only supply 2 A each.
