Multifunction measuring meter
( ECM700 )



The ECM700 series three-phase multifunction power meters are suit for up to 220kV system.
The compact device is designed for monitoring and displaying electric parameters include voltage, current, active power, reactive power, power factor, frequency, active energy and reactive energy.
Additional, ECM700 is user-configurable enable users to add extendable DI/DO modules. The auxiliary functions (SOE, TOU, harmonic analysis, dual-RS485 com) are so powerful enough to satisfy different applications.
