This movie shows the testing of one of our OCPC prototype circuits. This circuit is designed to reduce property damage caused by damaged cables, arcing, and other associated problems. This particular revision was designed to handle temperature ranges of -40C to +100C (the circuit senses temperature above 100C, and shuts down to avoid a hot surface ignition hazard. This temperature threshold can be changed). We currently have several versions designed to handle -55C to +125C (with adjustable thermal shutdown). The diode being used is a 2N555, a common 100mA diode. (Click on picture to play)
