The trigger plate is a masterfully integrated trigger plate featuring three-phase AC voltage regulation and power regulation (note: unsuitable for rectification). With phase shifting voltage regulation, this technology adapts seamlessly to various types of loads. Meanwhile, zero-crossing power regulation is tailored for constant resistance loads, ensuring precision and efficiency.
The phase-shifted voltage regulation method is a marvel, adjusting output voltage by altering the conduction angle size. This continuous trigger method offers unwavering output voltage stability, free from spikes, and effectively limits instantaneous current. It's the go-to method for transformers, inductive coils, and variable resistance loads. However, users should be aware of potential harmonic pollution to the power grid.
Transition to zero adjustment type for enhanced control.
The zero-crossing adjustment type is a sophisticated approach, operating precisely at the sine wave's zero point. By adjusting the on-off period of the sine wave, it modifies the output power, ensuring evenly distributed on-sine waves. This results in only minor fluctuations in voltmeter and ammeter readings. With multiple regulators, this method prevents current concentration, maintaining a pristine power grid with a high power factor. However, it cannot restrict instantaneous current, making it less suitable for inductive and variable resistance loads, but perfect for constant resistance loads.

P1 Potentiometer
The P1 potentiometer is a preamplifier potentiometer, expertly converting 4-20mADC into 0-5VDC. Pre-set at the factory, there's no need for user adjustment, ensuring optimal performance right out of the box.
P2 Potentiometer
The P2 potentiometer serves as the overcurrent alarm setting potentiometer. Its default factory setting triggers an alarm when the CT voltage surpasses 4.4VDC. Under standard conditions, no additional adjustments are necessary.
P3 Potentiometer
The P3 potentiometer is a current limiting potentiometer with a factory setting that automatically reduces output voltage once CT voltage exceeds 4VDC, until it falls back below this threshold. Users can customize the P3 potentiometer settings based on specific field requirements for tailored performance.
