Description
The Mitsubishi MDS-E-CV-37 is a power supply / converter unit from Mitsubishi Electric’s MDS-E CNC drive system, used in CNC machine tools to provide DC power to spindle and servo drive units.
It is not a motor or spindle drive, but the main converter section of the CNC drive system.

Features
- Acts as the main DC power supply for CNC servo and spindle drives
- Supplies stable DC link voltage (~300V DC) to all drive modules
- Integrated protection and monitoring functions
- Supports coordinated operation with MDS-E spindle (SP/SP2) and servo amplifiers
- Forced-air cooling for continuous industrial operation
- Designed for Mitsubishi MELDAS CNC systems
Role in CNC System
In an MDS-E system, the CV unit works like this:
AC Input → MDS-E-CV-37 → DC Bus → SP/SP2 spindle drives + servo drives
So it is the central power backbone of the CNC machine drive cabinet.
Typical Applications
- CNC machining centers
- CNC turning centers
- Multi-axis CNC systems
- Industrial automation machines
