SEM Three - Three phase Modbus energy meter

SEM Three is a three-phase 4 quadrants energy meter that allows to monitor the electrical parameters of your installation including active energy, reactive energy, voltage, current, power, maximum demand and more. These parameters are measured separately for each phase, what gives SEM Three high versatility to work as a three-phase analyzer or a triple single-phase analyzer.

In addition, the module of operating hours counting will allow to manage with precision how long an asset works to ease tasks of predictive maintenance, production control or energy efficiency. This feature allows to configure the electrical parameter that will start the counter, including all voltages, currents and powers, a threshold value and a delay time to start counting.

The design, occupying a single DIN rail module, allows that SEM Three can be placed easily at any installation.

The device has removal connectors for power supply (85-265 Vac), external current transformers (250 mA output) and RS-485 communications.

The communication of measured data works over Modbus RTU standard protocol.
