IRV1600-2800 HIGH POWER, WIRE

WOUND, METAL CLAD RESISTORS

The IRV1600-2800 (V=vertical) models are our highest power, wire wound, metal clad resistors.

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. These models are fully RoHS compliant.
