Aluminium 24 V industrial supply

The myVolts S-100-24 delivers 24 V at 4.2 A for 100 W total output, accepting AC 100-240 V input. An aluminium alloy chassis acts as the heatsink, so cooling is entirely passive. Built-in protection covers short circuit, overload and overvoltage events. The unit suits industrial automation, LED displays, CCTV, radio equipment, computer engineering, LED light bars and 3D printers.

Thermals, noise and power draw

Natural convection keeps the supply within its 0-40 °C working range without any fan, so acoustic output is effectively zero. Efficiency is rated high and DC ripple is kept low, reducing waste heat during normal operation. The aluminium body also provides excellent insulation strength. No active cooling components are present to wear out or generate noise.

Sustained-load behaviour

A 100 % total-load burn-in test confirms the supply can maintain its rated 100 W continuously within the specified temperature window. Overload, overvoltage and short-circuit protections remain active during prolonged operation. Storage tolerance spans -20 °C to 60 °C with humidity up to 95 % non-condensing. Output voltage is adjustable via the +V/ADJ terminal for fine-tuning under steady loads.

Perguntas sobre este artigo

How do I wire the AC input and DC output terminals on the S-100-24, and which connection step is most often missed?

Connect L and N to AC mains 100-240V, GND to DC negative, V to DC positive; the step most often missed is tightening the ADJ terminal after setting the output to 24V.

What maintenance or replacement will this 100W supply need after extended operation?

The aluminium alloy chassis uses natural convection cooling with no fan, so the only routine is keeping the ventilation slots clear of dust; electrolytic capacitors inside will eventually age and require unit replacement.

At what temperature limit does the S-100-24 begin to throttle or shut down during sustained full-load use?

The rated working range ends at 40°C ambient; above this the supply can no longer guarantee its 4.2A output and may trigger over-temperature protection.
