DC 12V 20A switching power supply

This myVolts unit converts AC mains voltage from 110V to 265V into a regulated DC 12V output rated at 20A. It uses free-convection cooling and includes overload, over-voltage and short-circuit protection. The compact metal enclosure weighs approximately 645g and carries CCC, FCC and CE safety marks.

Suitable for 3D printers.

It suits anyone powering 12V equipment such as 3D printers, WS2811, WS2812B, 2801, 3528, 2835, 3014, 5050, 5630 or 5730 LED strips, ham radio transceivers, car subwoofer amplifiers or RC LiPo chargers. It is not for builders who need an ATX-form-factor supply with motherboard connectors or multiple voltage rails. Buyers requiring higher output voltage or current should look elsewhere.

Output fixed at DC 12V 20A

The single specification that decides fit is the fixed DC 12V 20A output. The unit delivers this voltage from a wide AC 110V–265V input and operates between 0°C and 40°C with up to 95% non-condensing humidity. Verify that your load matches 12V and does not exceed 20A before purchase.

Questions about this item

What does the 20 A output mean for a 3D printer?

The unit delivers up to 20 A at 12 V, so a printer that draws less than that current will operate within the supply's rated capacity.

What does the AC 110-265 V input range mean for daily use?

The supply accepts any mains voltage between 110 V and 265 V at 50 or 60 Hz, so it works on most household circuits worldwide without a separate voltage selector.

How is this power supply mounted in a printer enclosure?

The metal case has mounting holes for screw fixing, and the terminal block provides L, N, GND, V and +V/ADJ connections for wiring directly to the printer's electronics.
