Description
The Mitsubishi D-AL-30K is an AC line reactor (input reactor) used in MDS-E / MDS-D CNC drive systems, installed between the AC power supply and the converter (CV) unit.
It is a protective and power-quality component, not a drive or motor.

š Mitsubishi CNC specification tables confirm that D-AL-30K is matched with MDS-E-CV-300 (30 kW converter unit).
āļø What it does
The D-AL-30K is installed in the CNC cabinet to:
- Reduce harmonic distortion back to the power grid
- Limit inrush current during power ON
- Protect the CV (converter) unit from electrical stress
- Improve overall power factor
- Stabilize incoming 3-phase AC supply
š Typical matching unit
