The PRV(V=Vertical) & PRH(H=Horizontal) models are metal-clad, wire-wound, high-power resistors designed for
industrial and other applications. Our extruded aluminum housing provides rugged and strong protection. These models are available with flying leads or tab terminals and can be ordered with inductive or non-inductive windings. Most common applications for these models are motor drives, braking and snubber applications and power sources for
industrial equipment.
