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.
