The RH/FRH series of resistors are aluminum housed and come in standard(RH) and non-inductive(RHN) windings. The use of injection molding technology gives these units excellent environmental protection. These resistors also utilize complete welded construction, chassis mounting for a heat sink effect and high stability at conventional power ratings.The most common applications for these models are motor drives, braking and snubber applications and power sources for industrial equipment.
