The UPM309 & UPM309RGW series of digital power meters provide an innovative solution for measurement and recording of the electrical parameters in AC power systems. It is particularly suitable for consumption analysis and control either as a standalone device or as part of a networked monitoring and control system. For example a BMS (building management system) or EMS (energy management system).

The instrument can communicate via an RS-485 serial port over MODBUS-RTU/ASCII protocol or via an Ethernet port over MODBUS-TCP protocol.

With options for 80A direct connect, 1/5A CT connect or Rogowski coil connect, this digital power meter is perfect for both retrofit and new applications, also covering a very wide current range with full scale value options from 80A up to 20kA

Furthermore, it is available with the WintoolNET software for remote management of the device. A web interface is also available in the Ethernet devices, a very useful function that allows for management of the instrument by a PC, tablet or smart phone connected on the network using a web browser.
