500 W AT Power Supply for 24 V Systems

The myVolts S-500-24 is an AT form-factor switch-mode supply that delivers 24 V at 20.8 A for a continuous 500 W output. It accepts AC input from 110 V or 220 V with a ±15 % tolerance, making it suitable for industrial automation, LED displays, CCTV and 3D printer installations. The aluminium-alloy chassis provides structural rigidity and acts as the primary thermal path. Built-in short-circuit, overload and overvoltage protection guards connected equipment.

Sustained 500 W Output with Low Ripple

The unit is specified for 100 % total-load burning tests, confirming it can maintain its full 500 W rating continuously rather than only in short bursts. Low DC ripple on the 24 V rail ensures stable power for sensitive electronics such as radio gear or precision LED drivers. Adjustable output via the +V/ADJ terminal allows fine-tuning within the design window. Efficiency remains high across the load range, limiting waste heat during extended operation.

Fanless Cooling from 0 °C to 40 °C

Natural convection through the aluminium alloy enclosure keeps the supply silent in normal use, with an operating temperature range of 0 °C to 40 °C and storage tolerance down to -20 °C. Humidity tolerance reaches 95 % non-condensing for damp environments. CCC, FCC and CE safety compliance marks confirm insulation strength and electromagnetic compatibility. The fanless design eliminates bearing wear and reduces long-term maintenance in 24/7 deployments.

Questions about this item

How much heat does the 500 W unit produce when running continuously at full load?

It operates from 0 to 40 °C with natural convection cooling and an aluminium alloy case that dissipates heat without a fan.

Which cables or connectors must I already have to wire the AC input and DC output terminals?

You need ring or fork terminals for the L, N, GND and V screw terminals, plus a small screwdriver for the voltage-adjust potentiometer.

Will this AT-form-factor supply fit alongside older AT motherboards and drives in the same chassis?

The 85 x 58 x 33 mm footprint matches the S-48-24 reference size, so it occupies the same mounting space as many legacy AT units.
