Product Description

Multi functional power meter
1.Product profile
Multi functional power monitoring instrument is a power monitoring instrument that integrates data acquisition and control functions, suitable for power systems of various voltage levels. This series of instruments can replace various meters, relays, transmitters, and other components. The instrument comes standard with RS485 communication and can achieve a maximum communication speed of 1.5Mbps by expanding Profibus communication, fully meeting the real-time data acquisition needs on site; Can accurately measure up to 63 harmonics; Users can achieve remote monitoring through software. The instrument is designed with humanization, and the terminals adopt a plug and play connection method, which is convenient for on-site wiring and maintenance; Provide multiple flexible and configurable expansion modules. This instrument has been widely used in various industries.
