Description
xThe Mitsubishi MDS-E-CV-370 is a CNC converter / power supply unit from Mitsubishi Electric’s MDS-E series, used as the main DC bus power source for spindle and servo drive modules in CNC machine tools.
It is not a motor or spindle drive, but the central DC power supply module of the CNC system.

📌 Source: Mitsubishi Electric CNC drive system specifications and MDS power supply documentation confirm the CV-370 as a 37 kW class converter supplying DC bus power for CNC spindle/servo drives.
What it does (simple explanation)
The MDS-E-CV-370 converts incoming AC power into a stable ~300V DC bus, which is then distributed to:
- spindle drives (SP / SP2 series)
- servo amplifiers
So it acts as the main electrical backbone of the CNC drive cabinet.
Features
- High-capacity DC link power supply for CNC systems
- Stable voltage regulation for multi-axis machining systems
- Supports regenerative energy from braking operations
- Forced-air cooling for continuous industrial duty
- Integrated protection (overcurrent, overvoltage, thermal monitoring)
- Designed for Mitsubishi MELDAS CNC architecture
Typical Applications
- CNC machining centers
- CNC turning centers
- Heavy-duty milling machines
- Multi-axis industrial automation systems
- Full Mitsubishi MDS-E drive cabinet systems
