Thermoregulator for biomedical electronic devices used in conditions of negative air temperatures.

The paper considers a thermostat unit that can be used in electronic devices operated at negative air temperatures. Operation of such a system makes it possible to use cheap electronic components designed for application in the temperature range of 0...+70 °C in the development of the device. An additional function of the thermostat is to ensure that the main device can be started only when positive temperatures are reached inside its housing. [ABSTRACT FROM AUTHOR]
