Industrial 12V 200W supply

This switch-mode unit delivers a regulated DC 12V output at up to 16.7A for 200W total power. It accepts AC input from 110V to 220V with a ±15% tolerance, making it suitable for industrial automation, CCTV, LED displays and 3D printers. The aluminium alloy chassis provides natural cooling without a fan. Safety compliance covers CCC, FCC and CE marks.

Sustained load behaviour

The supply is specified for continuous operation at 100% load after a full burn-in test, with high working efficiency and low DC ripple. Protections for short circuit, overload and overvoltage activate automatically to prevent damage during prolonged use. Rated working temperature spans 0°C to 40°C, so performance remains stable within that range under constant demand. Storage tolerance extends from -20°C to 60°C at up to 95% non-condensing humidity.

Installation notes

Wiring uses screw terminals labelled L and N for AC input, GND for DC negative and V for DC positive, with an additional +V/ADJ terminal for output voltage adjustment. No mounting dimensions or hole patterns are provided in the data, so mechanical fitting must be verified on site. The natural-cooling design requires unrestricted airflow around the aluminium case. Buyers who need forced-air cooling or a specific form factor should look elsewhere.

Questions about this item

How much heat does the 200W unit produce when running at full 16.7A load all day?

The supply uses natural convection cooling with no fan, so it runs silently; the aluminium alloy case acts as the heatsink and the unit is rated for continuous operation up to 40 °C ambient.

What cables or connectors must I already have to wire the S-200-12 into my 3D printer?

You need three mains wires for L, N and earth on the AC side, plus two DC cables for the V+ and GND terminals; the built-in screw terminals accept stripped leads directly.

Will the adjustable +V/ADJ output let me match the 12V rail of an older S-36-12 supply I want to keep in the same rig?

Yes, the +V/ADJ trimmer lets you fine-tune the 12V output so both units can share a common bus without voltage mismatch.
