General
PZ Series electric energy meters, adopting AC sampling technology, can measure many three phase grid electrical parameters such as current, voltage, power, electric energy etc. directly or indirectly. It may be used for local display, and connected with the control equipment to form measuring and controlling system.
Fitted with RS-485 communication port, adopting compatible 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.
PZ series meters have extra high price performance ratio, can simply replace traditional electric transducer and measuring meters As an advanced intelligent, digital front end acquisition component, this electric meters have widely used in various control system, SCADA system and energy source management system.
