P3 Potentiometer: Current Limiting Expertise
The P3 potentiometer is your go-to expert for mastering current limiting. With its default configuration automatically curtailing output voltage when CT voltage surpasses 4VDC, it ensures it stays below this threshold. Users can finely tune the P3 setting according to specific field conditions, guaranteeing optimal performance tailored to your unique requirements.
P4 Potentiometer: Phase Determination Precision
Essential for precise phase determination, the factory-adjusted settings ensure peak performance. It should remain unchanged to prevent false triggering, ensuring consistent and precise operation, thus maintaining the integrity of your system's performance and reliability.
P5 Potentiometer: Amplification Mastery
This potentiometer stands as a master of amplification, adeptly translating an AC 0-100mA current signal into a DC 0-4V voltage, known as CT voltage. The factory default is set at 100mA corresponding to 4V, yet it offers flexibility for on-site fine adjustments to meet specific needs, ensuring adaptability to your unique requirements, such as:
Load Current Selection and Transformer Configuration
1. For a load of 100A: Utilize a 100A/100mA transformer to achieve a precise 4VDC
2. When confronted with the formidable challenge of managing a substantial load of 150A, ensuring peak performance and unwavering reliability becomes paramount. The solution lies in the strategic selection of a robust 200A/100mA transformer. This meticulously chosen transformer is engineered to deliver an exact and dependable output of 3VDC, a pivotal element in maintaining your system's efficiency and stability. By choosing this transformer, you are actively fortifying your system's functionality, guaranteeing that it operates with flawless precision and efficiency, even under the most demanding conditions.
In the initial scenario, there is no necessity to adjust the P5 potentiometer. However, in subsequent situations, the precise calibration of the P5 potentiometer becomes absolutely critical.
