<P>PROBLEM TO BE SOLVED: To provide a temperature controller that can be stably operated when connected to a computer. <P>SOLUTION: A temperature controller can be connected to a computer. The temperature controller is supplied with power source from a computer to operate and is supplied with general power source to operate. And, the voltage used in the temperature controller includes a first voltage (range a) for digital signal processing. The temperature controller monitors variations in the first voltage flowing in the temperature controller. If the temperature controller detects that the first voltage exceeds a predetermined value (4.9 V), it includes a feedback circuit for reducing the supply of general power source, and the voltage (range b) of the power source supplied from the computer is smaller than a predetermined value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
