Abstract

PURPOSE: To give self-resetting function to a power control circuit by providing a circuit for periodically shorting the anode and cathode of a heat sensing cyristor.
CONSTITUTION: When DC power supply 1 is turned on, a condenser 7 is charged through a resistor 6. When this charge voltage has become large; a programmable uni-junction transistor 11 turns on; the charge accumulated in said condenser is released through PUT 11, a resistor 12, and the base and emitter of a transistor 10 to make continuity of said transistor 10 and to short the anode and cathode of a heat sensing cyristor 3; and the short of said cyristor 3 is repeated on the cycles determined dependent on the time constants of said resistor 6 and condenser 7. When the temperature of a heat detecting section has exceeded the set value thereof, said cyristor 3 turns on to supply power to load 2. When said temperature has come below said set value, said transistor 10 is shorted and, after turning off, does not turn on to stop the power supply of said load 2 even though short is cancelled.
