Open Frame Power Supplies

Open-frame typically means that the power supply will consist of a populated PCB minus any type of enclosure. The enclosure of the end-equipment that's running the power supply will, by default, provide physical protection for the open frame power supply.

Open frame power supply units are AC/DC switch-mode power supply units that have been built as printed circuit board (PCB) components without housing for installation into other devices. The 18W to 450W power range offers standard sizes of 3”x2”, 4”x2”, and 5”x3” to ensure easy installation into the end application.
