Versatile DC Power Supply for Projects

This myVolts switching power supply converts AC mains input to selectable DC output voltages of 12V, 20V, or 24V. It suits hobbyists, technicians, and integrators powering computers, monitors, cameras, or custom electronics projects. The unit delivers up to 200W of continuous power from a 100-220V AC source. Three distinct models are available, each offering different output current ratings for the chosen voltage.

Passive Cooling and Protective Enclosure

An aluminium alloy shell with a hollow structure provides rapid heat dissipation without a fan, ensuring silent operation. A protective junction box cover shields the transformer terminals from dust and accidental contact, improving safety during deployment. The robust metal housing adds compression resistance for durability in workshop or installation environments. Operation is straightforward: connect the applicable input and output wiring for immediate use.

Steady 200W Output Under Continuous Load

The supply maintains its full 200W rating during sustained operation thanks to efficient passive thermal management. Aluminium construction and the open-shell design prevent thermal throttling during extended use in projects, monitoring stations, or embedded systems. Protection features guard against overheating and electrical faults over long periods. The unit is rated for AC 240V input and must not be used in wet or damp locations.

Questions about this item

How do I wire the S-100-12 to a 240 V mains supply and which terminal block do I use for the 12 V output?

Connect the AC input leads to the L and N terminals rated for 100–220 V, then attach the load to the DC output terminals marked for the chosen voltage; the unit ships with a protective cover over the transformer junctions that must stay in place.

What ongoing care does the aluminium housing and junction-box cover need?

Wipe dust from the hollow shell vents with a dry brush every few months and check that the protective cover remains screwed down; no internal fan or filter exists to service.

At what load does the passively cooled case hit its thermal limit?

The 200 W rating is the maximum continuous output; running near that level relies entirely on the hollow aluminium shell for heat dissipation, so sustained full-load operation will raise case temperature until thermal equilibrium is reached.
