The controller uses a single-chip design, can be composed of AC power regulator output circuit with a variety of single and three solid-state relays, the power is regulated by the number of cycles of the output voltage to achieve. Can effectively reduce the interference on the power grid, in terms of heating can gradually achieve near-type temperature control, to prevent the temperature overshoot, particularly suitable for electric heating applications precision temperature control applications.
