Salt bath furnaces, industrial frequency induction furnaces, quenching furnaces, and molten glass temperature heating control.

Rectifier transformers, power regulators (pure inductive coil), electric furnace transformer primary side, magnetic field increase/decay regulation, DC motor control.

Voltage, current, power, lighting (Control of high-pressure sodium lamps must be matched with a voltage stabilization function and a PID control panel for smooth, infinite adjustment.)

Single-phase and three-phase welding machine control, electrolytic plating control, etc.
