Description
Using AC sampling technology, PZ Series electric energy meters can measure many three-phase grid electrical parameters such as current, voltage, power, electric energy, etc. directly or indirectly. It can be used for local display and connected with the control equipment to form a measuring and controlling system.
Fitted with the 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, electric parameters for transformation ratio, alarm, communication, etc., can be set up and controlled by keys on the faceplate.
PZ series meters have a high price-performance ratio and can replace traditional electric transducers and measuring meters. As an advanced intelligent, digital front-end acquisition component, these electric meters have been widely used in various control systems, SCADA systems,s and energy source management systems.
Features
1. The counter of the Three Phase Energy Meter has good sealing and anti-interference effects so that it can ensure accurate measurement.
2. Higher accuracy for voltage: Class 0.2, active energy: Class 0.5. Voltage can be connected to 660V.
3. The 92*92/ 88*88 design makes installation more convenient and saves time.
4. The clear LCD/LED screen allows you to see the data more clearly and prevents errors.
