The trigger plate is a marvel of engineering, meticulously designed for the precise regulation of three-phase AC voltage and sophisticated power modulation. While not intended for rectification, it features exceptional phase-shifting voltage control to accommodate a diverse range of loads. The zero-crossing power regulation is perfectly suited for constant resistance loads, delivering unparalleled precision and efficiency.
The phase-shifted voltage regulation method is a sophisticated technique that carefully adjusts output voltage by altering the conduction angle size. This continuous trigger approach guarantees a stable, seamless output free from voltage spikes, while effectively limiting instantaneous current. It is versatile for various load types and is commonly used in transformers, inductive coils, and variable resistance loads, although it could contribute to harmonic pollution in the power grid.
Switch to the zero-crossing adjustment type for peak performance and optimal efficiency.
The zero-crossing adjustment type operates flawlessly at the sine wave's zero point, ingeniously employing each complete sine wave cycle as its unit. By skillfully modulating the sine wave's on-off cycle, it achieves precise output power adjustments, ensuring an even distribution of on-sine waves. This results in minimal fluctuations in voltmeter and ammeter readings. When multiple regulators are used, this method effectively reduces current concentration, maintaining a high power factor and preventing power grid pollution. However, it cannot limit instantaneous currents, making it unsuitable for inductive and variable resistance loads, yet it remains ideal for constant resistance applications.
