The Replaceable Three Legged MOV
The NTM Tech Center continues to improve the PV solar electric equipment we supply to missionaries around the world. Part of this improvement includes incorporating new technology into existing products. Metal-oxide varistors (MOVs) have long been the mainstay of lightning protection. MOV’s act like very fast acting switches. When the voltage across them exceeds their […]
MOV’s have a life too…
MOV’s (Metal Oxide Varistor) are the round magical devices that the NTM Tech Center puts in many of our products.They are great at helping to minimize surges from induced lightning voltages, and other surges. Their use has helped to preserve the life of many electronic devices. However they are not without their limitations! MOV’s will […]
