Description

12V Open Frame Power Supplies take line (AC) voltage and output a steady 12V. Open Frame Switching Power Supplies, as you can see from the picture, are power sources where the circuit board and components are not totally enclosed, as with a desktop or wall wart power supply. Rather, they are encased in a metal casing with small holes throughout. This aids in air flow and cooling as the components are all open to the outside air. Our 12V Open Frame power supplies are offered in 100, 150 and 240 Watt sizes. (see data sheet documentation below for exact technical info on each one)

Low Line & High Line Voltage

There is a switch on the side of each power supply where you can change the input voltage range. This is important as line voltage will vary from country to country. Here in the U.S. we use low line (90-132VAC) whereas in Canada and Europe they use high line (176-264VAC). Make sure your switch is in the correct position before you hook this up to your line source!

Natural Cooling

The small-hole aluminum casing is made for direct air flow. When dealing with a lot of power, it is best to make sure there is a way to control the heat. The open design is enough to keep the circuitry cool enough so you do not have to worry about putting this in enclosed walls or ceilings.

Connections

All connections are made via screw-in terminals. This makes it super easy to connect all your wires with input ports for your line voltage and couple different output ports if you have multiple lights powered by the one power supply.

Mounting

There are mounting holes on the power supply if you need to mount to an object. Another way to mount would be using double sided velcro or tape.
