Overview:

ZN194E series power metre integrates the measurement of power parameters, power monitoring and assessment management, and is very suitable for real-time power monitoring systems. It can directly replace conventional power transmitters and measuring instruments. As an intelligent and digital front-end acquisition component, the instrument has been widely used in various control systems, SCADA systems and energy management systems.

Adopting AC sampling technology, can measure many single phase or three phase grid electrical parameters such as current, voltage,power, electric energy etc. directly or indirectly. It can be used for local display, and also can be connected with the control equipment to form measuring and controlling system.

Fitted with RS-485 communication port, adopting Modbus-RTU protocol. Meters can switch electric parameter signal into standard analog output, with four-channel (two-channel) switching input / two-channel switching output. Based on different requirements, by keys on the faceplate, electric parameters for transformation ratio, alarm, communication etc. can be set up and controlled.

Electricity measurement:

 1.  Phase voltage, line voltage, phase current,

 2.  Split phase active power and total active power

 3.  Split phase reactive power and total reactive power

 4.  Power and total apparent power are divided into two phases.

 5.  Split phase power factor and total power factor

 6.  Total active and total reactive watt-hour kwh energy

 7.  RS485 Modbus-RTU communication
