Overview

The UPM309 by Algodue provides an extremely versatile solution for distributed energy monitoring with options for both 1/5A CT connect and Rogowski coil connect for current measurement.

This multifunction power meter is panel mounted requiring a 96 x 96mm panel cutout.

With multiple integrated communications options these 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, including 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.
