A three-phase DIN rail mount digital power meter with options for 80A direct connect, 1/5A current transformer (CT) connect or Rogowski coil connect. Including fully bi-directional 4-quadrant measurements. The compact 4 DIN module size allows for quick installation. Communications can be via digital output, Modbus-RTU/ASCII, or Modbus-TCP. User interface is also available via the LCD display and web browser dashboard (Ethernet version).

See UPM309 Digital Power Meter (1/5A or Rogowski connect) for 96×96 panel-mount version.

Compatible with Huawei solar inverters for export limiting applications.

Product Description

The UPM209 and UPM309 by Algodue provide an extremely versatile solution for distributed energy monitoring in facilities. Offering a din-rail and panel mount option to suit the two standard methods for meter installation.

Both meters support 1/5A CT connect and Rogowski coil connect for current measurement. The UPM209 also supports direct connect (80A). This makes these meters perfect for use in both low and high current applications whilst maintaining +/- 0.4% accuracy.

With various communications options these multifunction power meters can connect easily with a BMS, EMS or PCMS via high level interface including Modbus-TCP/IP (Ethernet) and Modbus-RTU/ASCII (RS485).

The Ethernet models include an integrated webserver for remote viewing of real-time values, data-logging, device configuration and setup. Furthermore, this web-browser interface provides the option to setup NTP server time sync.

There are also options for standard and enhanced metering depending on the reporting requirements and project budget. The basic version includes reporting on standard active and reactive power values and THD. Whilst the enhanced version includes reporting on a range of min/max values and voltage/current harmonics up to the 15th order, along with various other advanced parameters.
