Motor & Power Manager

The new i.MWM is more compact, flexible and easily integrated into the overall Plant or Factory or Project. Complex and expensive Hardware & Software changes, integration are just not necessary.

In one device i.MWM you get intelligent higher level automation system with all integrated multi functions : Measurement, Protection, Monitoring, Control, Local Monitoring and Remote Monitoring. With i.MWM you save more space, save more time and important is you save more costs. However the best is yet to come : you get data to uncover all opportunities, detect abnormalities, avoid risks, track progress against goals and verify success.

It optimizes the use of Motor feeder, increases the plant and system availability and provides significant cost saving in planning, commissioning, operating and servicing.
