A cost-effective system architecture and apparatus for programmable automatic power supply testing. The system utilizes board level interface between various system testing modules and an Automatic Test Controller (ATC). The ATC receives coded test requests from the software on an industrial PC and control the various testing modules inside ATC to execute the tests. Test results were sent back to the PC and saved in a result file. A single industrial PC can control two or more ATC's and test two or more power supply units simultaneously. The ATC based test system is lower cost than the conventional Automatic Test Equipment which uses device level interface and standardized test devices.

The present invention is an efficient high voltage sensing mechanism that operates only when an individual needs to test the voltage across a wire. The present invention attaches around a tested wire using a jaw and a hook. The hook is tensioned using an expansion spring. The operator propels the hook outwards from the jaw, around the tested wire; thereafter, the expansion spring retracts to latch onto the tested wire against the jaw. An on-off switch is integrated into the mechanical hook device. As the hook is propelled outwards, the on-off switch moves into the “on” position, which powers the electrical processing and voltage analysis equipment. Once the hook is returned to the initial position, the on-off switch moves to the “off” position. This arrangement allows the present invention to remain unpowered for any instance a wire is not being tested. The present invention detects voltage through capacitive coupling.
