1. overtemperature protection AC power control device, comprise:

  • bidirectional triode thyristor T, bidirectional trigger diode D, protective resistance R, charging capacitor C, 80 ℃

    of Miniature temperature inductive switch K, or replace an identical temperature sensor, RT forms by positive temperature coefficient PTC element, it is characterized in that being close to one 80 ℃

    Miniature temperature inductive switch K on bidirectional triode thyristor T surface, perhaps replace an identical temperature sensor, positive temperature coefficient PTC element RT is arranged, utilization has the epoxy resin of heat conductivity to encapsulate as filler, bidirectional triode thyristor T chip temperature is transmitted to Miniature temperature inductive switch K or the PTC element RT of positive temperature coefficient is arranged.
