China Jfa3100 Factory Price Analog Display Single Phase Electric Digital Power Meter

Description:
JFA3100 series single phase voltmeter/power meter is a new intelligent meter which can programmable, It adopts large scale integrated circuit. Uses digital sampling technology to real-time measuring and control for voltage, current, active power, reactive power, power factor, phase value, frequency, active power, reactive power and apparent power. and remote transfer the measured electricity data by RS485 interface or analog transmit output. It is widely used in the intelligent power grid client's low voltage power signal collection, measurement, metering, monitoring, protection, system integration, complete intelligent power distribution cabinet and smart box-type change and other fields. The designs follows the national standard and industrial standard GB/T22264-2008Mounted digital display electric measuring instruments,JB/T10736-2007Low-voltage motor protectors, GB/T15576-2008Low-voltage reactive power compensation assemblies,
GB/T22387-2008Residual current operated relay etc.
