JKGHY intelligent combination low voltage reactive power measuring & control dev
Overview
JKGHY is an integrated controller for reactive power compensation and power distribution monitoring. It integrates data acquisition, communication, reactive power compensation, grid parameter measurement, and analysis.
If this product adopts RS485 communication method (JKGHY-Z), it can connect up to 32 pieces of HY series combined low voltage power capacitor compensation device or select 12V voltage output Control method (JKGHY-D), which can provide 12 or 16 steps Output (only one of the two methods can be selected)
