The PRV(V=Vertical) 1600-2800 watt 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 model are available with Tab terminals. The most
common applications for these models are motor drives,
braking and snubber applications and power sources for
industrial equipment.
