The trigger plate is an ingeniously integrated marvel crafted for the sophisticated regulation of three-phase AC voltage and masterful power modulation. While not intended for rectification, it showcases exceptional phase-shifting voltage control that caters to a wide array of loads. The zero-crossing power regulation is impeccably suited for constant resistance loads, offering unmatched precision and efficiency.
The phase-shifted voltage regulation type employs a refined method that meticulously adjusts output voltage through the alteration of the conduction angle size. This continuous trigger technique ensures a seamless, stable output devoid of voltage spikes, while adeptly limiting instantaneous current. It is versatile for diverse load types and finds common use in transformers, inductive coils, and variable resistance loads, although it may introduce harmonic pollution to the power grid.
Switch to the zero-crossing adjustment type for peak performance and optimal efficiency.
The zero-crossing adjustment type functions flawlessly at the sine wave's zero point, ingeniously using each complete sine wave cycle as its unit. By skillfully modulating the on-off cycle of the sine wave, it provides fine-tuned output power adjustments, ensuring an even distribution of on-sine waves. This results in negligible fluctuations in voltmeter and ammeter readings. When multiple regulators are employed, this method effectively minimizes current concentration, upholding a high power factor and preventing power grid pollution. However, it is unable to limit instantaneous currents, making it unsuitable for inductive and variable resistance loads, yet it remains ideal for constant resistance applications.
2. Advanced Trigger Plate Configuration
P1 Potentiometer: Precision Preamp
The P1 potentiometer is a highly calibrated preamplifier component that skillfully converts 4-20mADC into a precise 0-5VDC. It is meticulously set during manufacturing, requiring no further adjustments and ensuring a hassle-free operation.
P2 Potentiometer: Overcurrent Safeguard
The P2 potentiometer acts as the steadfast overcurrent alarm threshold setpoint. Factory settings ensure that when CT voltage exceeds 4.4VDC, an alert is triggered, negating the need for adjustments under standard operating conditions.
