FPV AC voltage transmitterIt is a signal conversion device designed specifically for industrial AC voltage signals. With core characteristics such as high measurement accuracy, good linearity, and strong anti-interference ability, it is widely used in fields such as power systems, industrial automation, and intelligent buildings. It accurately converts high-voltage AC signals into standard low-level signals, realizing remote monitoring and control of AC voltage. It is a key bridge connecting primary side high voltage and secondary side measurement and control equipment in industrial measurement and control systems.
Accurate communication signal conversion is its core competitiveness. The equipment adopts high-precision voltage transformers and linear amplification circuit design, with an input voltage range covering 0-500VAC to 0-10kVAC. It can linearly convert different levels of AC voltage signals into 4-20mA DC standard signals or 0-5V/0-10V DC voltage signals, with a conversion accuracy of up to 0.1 level and linearity ≤ 0.05% FS, and can accurately reproduce the trend of input AC voltage changes. In response to the periodic characteristics of AC signals, a built-in effective value conversion circuit can directly output a standard signal proportional to the effective value of AC voltage, avoiding the influence of waveform distortion on measurement results. In low-voltage distribution monitoring of substations, FPV AC voltage transmitters can convert 380VAC line voltage into 4-20mA signals and transmit them to the PLC system, achieving real-time monitoring and abnormal alarm of distribution voltage.

Strong anti-interference and stable operation design suitable for industrial environments. The equipment adopts an electromagnetic shielding shell and differential input circuit, which can effectively resist electromagnetic interference in industrial sites and avoid the interference signals generated by frequency converters, motors and other equipment affecting measurement accuracy. The power supply adopts a wide voltage design to adapt to different industrial power supply environments; The output circuit is equipped with overcurrent protection and short-circuit protection to prevent abnormal load from damaging the transmitter. In the rolling mill workshop of the steel plant, facing strong electromagnetic interference environment, the AC voltage transmitter can still stably output accurate signals, ensuring reliable monitoring of the power supply voltage of the rolling mill.
Easy installation and strong adaptability improve system integration efficiency. The device supports DIN rail installation and wall mounted installation, with a compact size that saves control cabinet space; The wiring terminals are designed to prevent accidental insertion, clearly distinguishing between input, output, and power interfaces, reducing the risk of wiring errors. Some models are equipped with LED indicator lights, which display the real-time operation status and signal output of the equipment, facilitating on-site debugging and troubleshooting. In the intelligent building power distribution system, multiple FPV AC voltage transmitters can be centrally installed in the distribution cabinet to monitor the voltage of lighting and air conditioning circuits on each floor, achieving refined management of building electricity consumption; In industrial production lines, it is used in conjunction with a frequency converter to monitor the output voltage of the frequency converter and ensure stable operation of the motor.
