FIELD: electricity. ^ SUBSTANCE: present invention relates to electrical engineering, electronics and heat engineering. The device for regulating temperature of an object contains power supply circuits connected to each other, series-connected temperature sensor, amplifier, connected to the second power supply circuit, and a transistor, the output of which together with the first power supply circuit forms the output of the device for connecting to a heater. The device also contains series-connected second temperature sensor, second amplifier, connected to the third power supply circuit, and a current generator, the output of which is connected in series with the above mentioned transistor and connected to the common power supply circuit of the device. The first and second temperature sensors, transistor and current generator can minimise transient thermal impedance relative the object, on which the device is fitted. ^ EFFECT: increased reliability through elimination of probability of heating whenever there is a fault in the device, and increased functional capabilities of the device due to provision for combining the role of temperature regulator and heater without lowering reliability of the executed function. ^ 3 cl, 1 dwg |
