A power supply trainer for teaching basic power supply circuits is disclosed, which includes a metal frame having a vertically opposing posts with a base stand and caster. A flat transparent non-conductive panel mounted to the frame serves as visual display. A channel aluminum member attached to the bottom part of the said panel acts as casing for the step-down transformer and control member. A plurality of terminal blocks containing the electronic components, integrally attached to the panel with each block having. a plurality of terminals adapted to interconnect with each other to form the desired power supply circuit. A control member connected to the terminal blocks and mounted to the channel aluminum member, for controlling the ac input voltage to the terminal blocks; said control member having a plurality of input and output terminals adapted to interconnect with the terminal blocks. A step-down transformer connected to the terminal blocks is adapted to energize the device. |
