ABSTRACT:
A power supply with interchangeable plug capacity and interchangeable power input modules includes a casing, an electrical plug detachably mounted in the casing, allowing the user to accommodate various power source configurations and voltage supply levels without manually setting the unit for the available power source, resulting in increased user safety and convenience. Releasable locking mechanisms are included to engage the interchangeable electrical plug. The locking mechanisms can be released by a user to allow the plug to be moved to the detached position. A preferred form of electrical connection between a detachable plug and casing comprises a submerged conductor configuration to protect the user or passerby from electric shock. A variety of interchangeable electrical plugs can be fitted to the same casing for interface with a transformer in the power supply casing. Each such plug is internally wired to configure the primary windings of the transformer automatically to present a substantially constant AC voltage at the secondary windings of the transformer irrespective of the magnitude of the supply voltage standard.
