ULV/ULH TYPE (UL^®Approved)

The ULV(V=vertical & ULH(H=horizontal) models are UL approved metal-clad, wire-wound high-power resistors designed for

industrial and other applications. Our extruded aluminium 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. To conform to UL

safety requirements, ULV/ULH models differ from IRV/IRH models in that: The resistance range is smaller, the flying leads

are UL approved and the dielectric strength depends on the ohmic value.
