The temperature controller is an integrated intelligent temperature control instrument. It adopts a fully digital integrated design, with programmable temperature curve or fixed-point constant temperature control, multiple PID adjustment, output power limit curve programming, manual/automatic switching, soft start, and alarm. Switch output, real-time data query, communication with computer and other functions, the digital temperature meter and ZK thyristor voltage regulator are combined into one, which integrates temperature measurement, adjustment and drive. The meter directly outputs the thyristor trigger signal, which can drive each Thyristor-like loads.
