24V 500W Industrial Power Supply

The myVolts S-500-24 is a 24V 20.8A 500W switch-mode power supply driver designed for industrial automation, LED displays, CCTV, radio equipment and 3D printers. It accepts AC 110V or 220V input with a ±15% tolerance and delivers a regulated DC 24V output with an adjustable voltage trim. The unit features overload, overvoltage and short-circuit protection and has passed a 100% full-load burn-in test.

Suited for fixed 24V DC loads up to 20.8A

This supply fits builders who need a protected 24V rail for LED light bars, automation controllers or printer heated beds in a 0°C to 40°C operating range. It is not intended for builders who require ATX-standard connectors for PC motherboards, multiple voltage rails, or a unit certified for continuous operation above 40°C ambient.

Aluminium chassis with natural convection cooling

The aluminium alloy enclosure measures approximately 85 x 58 x 33 mm and relies on passive cooling, so it needs free airflow around the case. Terminal blocks provide L and N for AC input, GND and V for DC output, plus an ADJ terminal for fine voltage adjustment. No fan headers or modular cables are included, freeing internal space in compact enclosures.

Questions about this item

What AC mains voltage does the S-500-24 require to operate?

The unit accepts AC 110 V or 220 V with a ±15 % tolerance, so it works on standard household or industrial mains worldwide.

Can I keep my existing 24 V DC equipment when installing this supply?

Yes, the output provides DC 24 V at up to 20.8 A with overload, overvoltage and short-circuit protection, matching typical 24 V industrial loads.

How do I verify the supply is delivering the rated 500 W after wiring it?

Measure the DC output terminals with a multimeter under load; you should read approximately 24 V and the current draw should not exceed 20.8 A.
