AS-Interface bus control module MLK30A. Output speed adjustable from 8.6 to 43rpm. See data plate for full details. If you do not require the AS-I control interface the motor can be operated in a fixed speed mode (star or delta) by attaching the power direct to the motor tails.
If you require the variable speed drive with digital inputs opposed to the AS-I bus I can source the parts to do this please ask prior to ordering.
