The PRV(V=Vertical) 600∼1200 watt models are metal-clad, wire-wound, high-power resistors designed for industrial
and other applications where high wattage is a must. Our extruded aluminum housing provides rugged and strong
protection. Most common applications for these models are motor drives, braking and snubber applications and power
sources for industrial equipment.
