InMonitor is a device that monitors and does online communication in real time.

It has 12 inputs for external current sensors (10-500 A) and 3 simple voltage inputs (231 V), allowing you to monitor up to 12 single-phase loads, 4 three-phase loads with 3 current readings per load or 6 three-phase loads with 2 current readings per load.
InMonitor’s acquisition rate its 1 kHz. The effective and the active power values are calculated by digital integration with an integration period of 100 ms (5 cycles of a 50 Hz wave). The data recording period is from 1 to 30 minutes. The values recorded correspond to their average over the registration period.
