Product Description

The UPM209 digital power meter provides an innovative solution for the measurement and recording of electrical parameters in commercial AC power applications. They are particularly suitable for consumption analysis and control, providing a cost-effective yet advanced power monitoring solution.

With options for 80A direct connect, 1/5A current transformer (CT) connect, or Rogowski coil connect the UPM209 can be used in a wide range of three-phase power monitoring applications including low power applications of only a few amps, to high power applications up to 20kA.

Available with RS485 Modbus-RTU/ASCII or Ethernet Modbus-TCP communications, these power meters can be easily integrated with third-party control and monitoring systems. E.g. PLC control systems, building management systems (BMS), and power control and monitoring systems (PCMS). Furthermore, the Ethernet version provides an integrated web server for remote viewing via web browser and FTP data transfer.
