BY75 Series Reactive Power Compensation Controller
The BY75-24 reactive power compensation controller is a new type of distribution measurement and control equipment that integrates funclions such as data collection, reactive power compensation, and power grid parameter analysis. It is suitable for monitoring and reactive power compensation control of AC 0.4KV and50Hz low-voltage distribution systems.
Product Description
The BY75-24 reactive power compensation controller is based on a high-speed digital signal processor and adopts AC sampling. The human-machine interface is a 128X64 dot matrix large screen LCD display. it has power distribution monitoring, reactive power compensation, harmonic analysis, adaptive freqvency algorithm, and input signals that vary between 45Hz and 55Hz.
