Product Description

Product Description

Unveil the sophisticated marvel that is our trigger plate—a masterclass of integrated innovation designed for the precise regulation of three-phase AC voltage and deft power modulation. While not crafted for rectification, it excels in phase-shifting voltage control, seamlessly accommodating a diverse spectrum of loads. The zero-crossing power regulation type is exquisitely refined for constant resistance loads, promising unparalleled precision and efficiency.

Experience the refined elegance of phase-shifted voltage regulation, an advanced technique that meticulously adjusts output voltage by modifying the conduction angle. This smooth trigger mechanism ensures a continuous, stable output free of voltage spikes while expertly managing instantaneous current. Its versatility across varied load types makes it a top choice for applications such as transformers, inductive coils, and variable resistance loads, although it may contribute to harmonic disturbances in the power grid.

Opt for the zero-crossing adjustment type to achieve superior performance and peak efficiency.

The zero-crossing adjustment type operates with remarkable precision at the sine wave's zero point, utilizing each complete sine wave cycle as its benchmark. By skillfully modulating the sine wave's on-off cycle, it delivers finely tuned output power, ensuring even distribution of on-sine waves. This results in minimal fluctuations in voltmeter and ammeter readings. In scenarios with multiple regulators, this method effectively mitigates current concentration, upholding a high power factor and preventing power grid pollution. Though it cannot limit instantaneous currents, making it less suitable for inductive and variable resistance loads, it remains ideal for constant resistance applications.

Our unwavering commitment to quality is evidenced by our 18-month warranty.

P2 Potentiometer: Guardian of Overcurrent Safeguards
The P2 potentiometer serves as the steadfast overcurrent alarm threshold setpoint. Factory settings ensure alerts activate when CT voltage exceeds 4.4VDC, negating the need for adjustments in standard conditions, offering peace of mind and dependable protection.

P3 Potentiometer: Mastery in Current Limiting
The P3 potentiometer specializes in mastering current limiting. With its default setting automatically reducing output voltage when CT voltage surpasses 4VDC, it keeps it below this level. Users can fine-tune the P3 setting based on specific field conditions for optimal performance.

P4 Potentiometer: Precision in Phase Determination
The P4 potentiometer is crucial for phase determination. Pre-adjusted at the factory for peak performance, it should remain unchanged to prevent false triggering, ensuring consistent and accurate operations.

P5 Potentiometer: Masterful Amplification
The P5 potentiometer excels in amplification, expertly converting an AC 0-100mA current signal into a DC 0-4V voltage, known as CT voltage. The factory default is set at 100mA equivalent to 4V, but it can be finely adjusted on-site to meet specific requirements, such as:
Load Current Selection and Transformer Configuration
1. For a load of 100A: Employ a 100A/100mA transformer to achieve an exact 4VDC
2. For a load of 150A: Opt for a powerful and reliable 200A/100mA transformer. This choice guarantees an exact 3VDC, delivering peak performance and ensuring the system's optimal operation.
In the initial scenario, adjusting the P5 potentiometer isn't necessary. However, in the subsequent scenario, precise tuning of the P5 potentiometer is essential to maintain system integrity. At 150A, the current transformer yields just 75mA. After amplification, the CT voltage is a mere 3VDC, falling short of what the trigger board requires for effective system protection. To rectify this, recalibrate the P5 potentiometer to elevate the CT voltage to 4VDC at a 75A current signal. Utilize a multimeter to accurately measure the CT voltage on the trigger board. For detailed guidance, refer to the figure below illustrating the exact location on the trigger board for your adjustments.
