MQC Series
The amplifiers of the MQC series are based on
the MS series. They are designed as compact amplifiers. The connection
is via a transformer with separated primary and secondary winding on the
existing net.
The MQC series contains all groups of function of a modern servo
amplifier:
- four-quadrant speed control with current control
- internal power supply for controller electronics (± 15 V) and for
supply of external components
- armature current choke
- 3 ph. rectifier
- internal braking regulator
- compact housing
