CONTROL UNIT OF TEMPERATURE CONTROLLER Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: control unit has ripple voltage source, stages using disinter with thermally-independent change-over voltage. Voltage divider having at least two midpoints is introduced between ripple voltage source and first stage using disinter with thermally-dependent changer-over voltage and second stage using disinter with thermally- independent change-over voltage. Stage using disinter with thermally-dependent change-over voltage is connected to one midpoint of voltage divider. Stage using disinter with thermally-independent change-over voltage is connected to one midpoint of voltage divider. Stage using disinter with thermally-independent change-over voltage is connected to other midpoint of voltage divider. Given circuit enables effective and accurate temperature control of electrical engineering objects or medium within range of -60+150 C. It may also be used as thermal fuse. EFFECT: enhanced control. 3 cl, 4 dwg
