回路。 a heater resistance wire that heats a temperature-controlled object; a switch that switches and connects a power source between both ends of the heater resistance wire and a tap provided in the middle of the resistance wire;
a power control circuit provided in a power supply line to the heater resistance wire; the switch is configured to switch the switch so that current flows from one end of the heater resistance wire to the other end when the power supply is at a high voltage; When the voltage is low, both ends of the heater resistance wire are connected in common, and the switch is switched so that a current flows between this point and the tap, and the power applied to the heater resistance wire is controlled by the power control circuit. A heater control circuit for two power sources, characterized in that the temperature of the temperature controlled object is adjusted to a set temperature.
