Midi / Maxi Maestro

Discontinued Series - Still Available

(Call Microcon for Stock Availability and or replacement)

DC Servo Drives 8 to 25 A
The Maestro range of dc brushed servo drives are manufactured to the latest surface mount specifications ensuring quality, reliability and above all a cost effective solution to low power dc servo applications. Performance matched to a range of permanent magnet dc servo
motors Matador. The Maestro delivers powerful, accurate motor control in diverse applications such as robotics, transfer lines, positioning, indexing.

The 20kHz switching frequency ensures silent operation and
the Maestro/Matador combination is characterised by the
accuracy of its speed and control loops. The Maestro range
comes in three physical sizes, Mini, Midi and Maxi.
