Description
RPTF planar thick film and high-power non-inductive resistor is of high frequency and non-inductive. Water-cooling or air-cooling is needed during long-time operation, which keeps the substrate center temperature not more than 85°C. Power range is 100w ~ 800w. It is applied to Electrical equipment of power generation, power transmission, variable speed drive, etc.
