The "J" SPEC model JVR, exclusively designed and manufactured by Kinetics, is ideally suited for applications such as scrap lifting magnets or cranes where DC faults are a common occurrence. The JVR addresses the problem of blown semi-conductor fuses resulting from cut magnet cables, shorted magnets or crane rail faults. Listening to customers, and breaking from traditional diode rectifier design, Kinetics has designed and thoroughly tested a solid state rectification system that eliminates the expense of silver sand fuses that conventional designs use to protect the rectifier semi-conductors.
