Product Overview: HertzKron HK-PFX Series Intelligent Power Factor Controller
Achieving Digital Precision in Power Quality Governance through High-Speed DSP Sampling and Vector Logic.
The HertzKron HK-PFX Series is the intelligent core designed for modern, harmonic-rich industrial environments. By performing tens of thousands of physical analyses per second on the sampling current and voltage, this controller captures real-time grid phase fluctuations and drives compensation branches to maintain target power factor consistency. Featuring a signature Orange & Blue Intuitive UI, it combines high-visibility aesthetics with industrial-grade capacitive touch technology for long-term physical reliability in harsh distribution environments.
Core Technical Highlights
⚡ 1. High-Precision Signal Acquisition (Sampling Logic)
True RMS Measurement: Equipped with a 16-bit high-speed Analog-to-Digital Converter (ADC), the controller performs high-frequency discretization of sampling current and voltage. It maintains a physical measurement accuracy of Class 0.5, even in environments with severe waveform distortion caused by non-linear loads.
Electromagnetic Inertia Tracking: The system filters out transient noise to ensure that all compensation decisions are based on the underlying physical state of the grid, eliminating momentary electrical artifacts.
🛡️ 2. Advanced FFT Vector Algorithm (Harmonic Defense)
Harmonic Decomposition: Utilizing Fast Fourier Transform (FFT) algorithms, the HK-PFX controller automatically decomposes complex sampling signals into fundamental and high-order harmonic components.
Anti-Oscillation Mechanism: By calculating the precise displacement power factor and total power factor, the controller prevents frequent switching and resonance "hunting" during high harmonic distortion, protecting the lifespan of connected capacitor banks.
🔒 3. Industrial Safety & Global Compliance
Dual International Certification: Fully compliant with EU LVD and EMC standards, bearing both CE and EAC marks. It is engineered with superior physical immunity against electromagnetic interference (EMI).
Triple-Layer Protection: Features integrated physical protection for Overvoltage, Undervoltage, and Total Harmonic Distortion (THD) alarms, ensuring the absolute safety of the reactive power compensation system under extreme stress.
