    FAQ

    Q1: What is a 4-wire power controller?

    4-wire power controller is a three-phase power regulating device, mainly used for precise control of voltage and power in industrial loads. It supports stable voltage regulation and reliable driving, features standardized wiring and high safety, and can be adapted to various industrial heating, lighting, and resistive load scenarios.

    Q2: What is the difference between phase control and zero-crossing control?

    Phase control can continuously adjust the output, operates stably without jitter, but generates a small amount of harmonics; zero-crossing control turns on at the zero-crossing point of the voltage, has no harmonic interference, is more environmentally friendly, but has slightly lower adjustment accuracy and slight fluctuations in output. Users can choose the corresponding mode according to the load type and usage requirements.
