Product Description

General Features

UPM309 is an innovative instrument for measurement and recording of the electrical parameters. It is particularly suitable for consumption analysis and control, with an excellent quality/price ratio.

UPM309 is the ideal instrument to establish the measurement points on the plant. The instrument can communicate through the RS485 serial port by Modbus-RTU/ASCII protocol or through Ethernet port by Modbus-TCP protocol.

Furthermore, it is available the WintoolNET software for the instrument remote management. Web interface is also available in case of instrument with Ethernet port: a very useful function that gives the possibility to manage the instrument by any PC connected on the network.


  • Energy audit.
  • Monitoring system and energy control.
  • Individual machine load monitoring.
  • Power peak control.
  • Switchboards, gensets, motor control centers, etc.
  • Remote metering and cost allocation.


  • UPM309 provides fully and accurate information on the load in the measurement point and it allows to calculate the costs of the energy consumption.
  • Data read by PC allows to generate consumption profiles, recorded values trend, alarms/events report and costs calculation as well as critical values identification.
  • Available the remote firmware upgrade of the instrument.
