The IRV/ULV600-1200 (V=vertical) models are our standard higher power, wire wound, metal clad resistors.
The ULV600-1200 are the UL approved versions of the IRV600-1200 models. These models have an extruded
aluminium housing providing strong and rugged protection. Options include flying leads or tab terminals and
inductive or non-inductive windings. The most common applications for these models are: motor drives,
braking and snubber applications and power sources for industrial equipment.SPECIFICATIONS
