MS / MRM Series
![picture of a ms](pics/ms.jpg)
The amplifiers of the MS/MRM series contain
all groups of function of a modern speed control system. They are
four-quadrant speed controllers with internal current control in Europe
size arranged for control of permanent magnet servo motors.
MRM Series:
- DC power supply (MSMN/W)
- especially for multiple axes application in rack version
- 100 % compatibility to the former MSM series
MS Series:
- internal power supply for controller electronics (± 15 V) and for
supply of external components
- armature current choke
- 1 ph. rectifier for AC power supply up to Irms=4/6 A
- internal braking regulator
