If you’re looking for a reliable power supply for your Prusa i3 3D Printer or any other type of machine with similar power needs, this 12V 240W Power Supply is the ideal choice. It offers auto-switching 88V - 264V AC input, has a built in passive PFC choke, an on-board cooling fan with on/off switch, as well as short circuit, overload, under voltage and over-temperature protection features. These all culminate into a consistently reliable power supply capable of meeting the needs of most standard 3D Printers.

The S-240-12 outputs 12V DC, with a voltage adjustment range of 10 – 14V, and is rated at 18A. It offers a quick 1000ms startup time and an impressive 82% efficiency, resulting in a max power of 240W and a True Power of around 216W. This is enough to power all of the Stepper Motors, the drivers, the mainboard, the hotend and extruder, as well as all of the other parts contained within a 3D printer like the Prusa i3, with all of the necessary protection features to keep your 3D Printer Parts safe from electrical damage.

Typical Applications for 12V 240W Power Supply Units:

This 12V 240W Power Supply has a relatively small form factor of 215 x 114 x 50mm, allowing you to discretely integrate it into other projects as well, without needing an excessive amount of space. And while this power supply is stocked primarily for Prusa i3 3D printers, it can provide power to almost any parts or machine with similar power requirements. Just be sure to leave ventilation room for the fan, otherwise the over-temperature protection will kick in and stop operations until the components cool off.
