The temperature centralized controller circuit consists of the power supply circuit and temperature control circuit, and the circuit is shown as the chart. The power circuit is composed of the power switch SO, fuse FUO, power transformer T, brigde rectifier UR, filter capacitors C1 and C2, three-terminal regulator integrated circuit IC, current-limiting resistor RO and power indicator LED VLO. Temperature control circuit is composed of the relays K1 ~ Kn, thermal relay sKR1 ~ KRn, resistors R01 ~ R0n, R1 ~ Rn, thyristors VT1 ~ VTn, fuses FU1 ~ FLn, heater case power switches S1 ~ Sn, electric heater(heater case,electric heater), EH1 ~ EHn and work instructor LEDs VL1 ~ VLn. RO ~ Rn and R01 ~ R0n use 1/4W carbon film resistors or metal film resistors.
