ENGINE CONTROL SYSTEMS
One manufacturer incorporated STO-P as standard equipment on one of their advanced engine control systems. STO-P solved persistant engine faults that had been blamed on software bugs in the engine control computer. After spending countless man-days scouring computer code for bugs and timing errors, an alert engineer placed a STO-P in the power supply line and the problems ceased!

REMOTE SENSING (SOLAR POWERED)
Remote sensing sites often rely on 12 or 24 volt battery power supplies recharged by solar panels. While this seems like a reasonably foolproof way of supplying power, engineers often find that equipment failures are abnormally high. One cause has been induction caused by nearby lightning. Solar panels present a large conductive surface area which is a very effective antenna for coupling high voltage transients into equipment. 

Battery failure, regulator failure, or batteries nearing the end of their service life create overvoltages situations as solar panels drive a 12 volt system to 20 volts or more. 

STO-P UPS series protectors solve both problems.
