PDF File

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.
