Product Description

Product Description

Discover the pinnacle of technological elegance with our trigger plate, a marvel of innovation intricately designed for the precise regulation of three-phase AC voltage and proficient power modulation. While not crafted for rectification, it excels in phase-shifting voltage control, seamlessly handling a diverse range of loads. The zero-crossing power regulation type is expertly optimized for constant resistance loads, delivering unmatched precision and efficiency.

Experience the sophistication of our phase-shifted voltage regulation type, employing a cutting-edge approach that fine-tunes output voltage by modulating the conduction angle. This flawless trigger mechanism ensures a steady, uninterrupted output, free from voltage spikes, while expertly managing instantaneous current. Its versatility across various load types makes it the ideal choice for applications like transformers, inductive coils, and variable resistance loads, notwithstanding the potential for harmonic interference in the power grid.

Select the zero-crossing adjustment type for unparalleled performance and peak efficiency.

With pinpoint accuracy at the zero point of the sine wave, the zero-crossing adjustment type expertly employs each complete sine wave cycle as its unit. By skillfully modulating the sine wave's on-off cycle, it delivers precisely adjusted output power, ensuring a uniform distribution of on-sine waves. This results in minimal fluctuations in voltmeter and ammeter readings, even in complex regulator scenarios. This method significantly reduces current concentration, upholds a high power factor, and prevents power grid contamination. While it lacks the ability to limit instantaneous currents, making it less suitable for inductive and variable resistance loads, it remains the perfect choice for constant resistance applications.

After Sales Service

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

P2 Potentiometer: Overcurrent Safeguard
The P2 potentiometer serves as the steadfast overcurrent alarm threshold setpoint. Factory presets ensure an alert is triggered when CT voltage surpasses 4.4VDC, negating the need for adjustments in standard operating conditions, offering peace of mind and dependable protection.

P3 Potentiometer: Current Limiting Expertise
The P3 potentiometer masters current limiting with finesse. Its default configuration automatically decreases output voltage when CT voltage exceeds 4VDC, maintaining it below this limit. Users can finely adjust the P3 setting based on specific field conditions for optimal performance.

P4 Potentiometer: Phase Determination Precision
The P4 potentiometer is crucial for phase determination. Factory calibrated for optimal performance, it should remain unchanged to avoid false triggering, ensuring consistent and accurate operation.

P5 Potentiometer: Amplification Mastery
The P5 potentiometer excels in amplification, adeptly converting an AC 0-100mA current signal into a DC 0-4V voltage, known as CT voltage. The default factory setting is 100mA equivalent to 4V, but it can be finely adjusted on-site for specific needs, such as:
Load Current Selection and Transformer Configuration
1. For a load of 100A: Deploy a 100A/100mA transformer to achieve a precise 4VDC
2. For an impressive 150A load: Opt for a robust and reliable 200A/100mA transformer. This choice is crucial to achieve a precise 3VDC, ensuring peak performance and reliability in your applications.
In the initial scenario, there is no need to alter the P5 potentiometer. However, in the subsequent scenario, meticulous fine-tuning of the P5 potentiometer becomes essential. At 150A, the current transformer's output registers a mere 75mA. Once amplified, this results in a CT voltage of only 3VDC, which falls short of the requirements to adequately protect the trigger board and the entire system. To rectify this, recalibrate the P5 potentiometer so that at a 75A current signal, the CT voltage elevates to a robust 4VDC. Utilize a multimeter to measure the CT voltage directly on the trigger board. Refer to the accompanying diagram below, which indicates the precise location on the trigger board to facilitate your adjustments
