Abstract
Abstract Disclosed is a modular power supply having a case made up of top, bottom and side plates. Each plate has either a male or female portion at the edge which is slidably interconnectable with the edge of an adjacent plate. In addition, male and/or female portions located on the top, bottom and side plates matingly engage with similar female and/or male portions on a handle, output device receptacle, etc. The internal portions of the power supply are divided into three modular components. The first modular component includes a transformer and a primary coil select switch and is connected to the rear portion of the case preventing the case sides from slipping apart from the top and bottom plates. A second modular component is a printed circuit board interconnectable with the first modular component and containing a temperature control circuit and an air pump and motor combination. The second modular component is slidably received into the case. The third modular component comprises a front panel, including controls for the temperature control circuit and sockets for connecting an output utilization device to the present invention. Additionally, an air switch is provided on the front panel which will selectively apply either a vacuum or a variable pressure source to the output utilization device. When the first component is connected to the case, it also prevents separation of the plates making up the case and also retains the printed circuit board in its position in the case.
