Why MICROMASTER Mid-Power and Cabinet are still critical today

In large plants, replacing the drive is not equivalent to changing a single component:

involves the electrical distribution system
modifies line protection
requires plant re-qualification
causes extended production downtime

In many cases, the plant shutdown costs more than the retrofit itself.

For this reason, advanced maintenance is often the only sustainable solution.

What MICROMASTER Cabinet and Mid-Power are

They are modular drive systems composed of:

power supply units
power modules
control boards
cooling systems

The architecture is designed for high reliability and continuous operation.
