Brief Description:  Over-voltage Protection module test

An over-voltage protection (OVP) device is recommended in an aircraft electrical system (aeroelectric connection) and it is intended to shut off the alternator voltage output in the event the voltage regulator fails to do its job, which is to maintain a 12V-14V voltage source regardless of what the alternator puts out. There are two popular devices out there for this job: one from the aeroelectric connection, and a 'supposedly' more elegant version from periheliondesign.com. I have the latter, and though pricier, is incredibly compact, and fits nicely into my electric supply tray (Image 1).

As part of the installation, I am supposed to test the device for its ability to shut the system off under load, and to do that I need a variable voltage supply capable of providing at least 16.2 volts in gradual manner. So, for $20 on ebay, I found a 15A 12-24V variable power supply unit tha did the job. The tricky peice is that the manufacturer stipulates that to make the test realistic, the load has to be typical of an aircraft, like about 8A. So in addition to needing this power supply that can handle this kind of amperage, I needed to find an 8A load.
