temperature controlling in electric and radiotechnical systems. SUBSTANCE: controller includes connected in series: heat sensitive unit 1, amplifier C with switching characteristics of comparator and heater 3. High-resistance resistor 6 is connected in series with circuit of heat sensitive resistor 5 of heat sensitive unit 1. Resistor 4 of unit 1 is connected with common busbar, circuit of heat sensitive resistor is connected with power supply bus. Electric circuit of amplifier 2 reduces power consumption of amplifier at least by order when heater is cut off. EFFECT: reduced power consumption at turned off heater, lowered size of apparatus, simplified mounting of temperature controller directly in heated object. 2 cl, 4 dwg
