AFM-8A High Performance Power Analyzer


AFM-8A has Developed for AFC*(Auto Frequency Control) high performance measurement and frequency update, its update up quicker than 100mSec. multifunction power analyzer provides high-accuracy measurement and is designed for single phase and three phase application. It includes 4 Digital inputs, 4 Relay outputs, and a RS-485 Modbus RTU Communication port. The user can choose one more communication port, and 2 Analog outputs for output expansion.

It provides measure voltage and current of the 2~63 harmonic, and it shows CO2 emissions, which is suitable for power monitoring, management and analyze power quality. It has TOU (time-of-use) function and 4MB Flash memory capacity, allowing users to record data for a long time. It also has a software line adjustment function to reduce the on-site line adjustment work.


*Automatic Frequency Control (AFC) frequency modulation service is one of the emerging technologies, because the energy storage system has the characteristics of rapid charging and discharging, through the active adjustment of the charging and discharging action to adjust the frequency of the power system, it can help maintain the frequency drift caused by load fluctuations, which is very suitable as a system stability response scheme under the high proportion of renewable energy.
