SCRC100-LB12 type reactive power compensation controller

OneSCRC100-LB12 type reactive power compensation controllerProduct Overview

The SCRC100-LB12 reactive power compensation controller is a new type of distribution measurement and control equipment that integrates data acquisition, communication, reactive power compensation, and other functions. It is suitable for reactive power compensation control in AC 0.4KV, 50Hz low-voltage distribution systems. The SCRC600-LB12 reactive power compensation controller is based on a high-speed digital signal processor and uses AC sampling. It has functions such as sampling calculation, reactive power compensation, harmonic analysis, and communication, and supports RS485 communication port and MODBUS protocol.
