Information About MDS-DH-SP-40

The MDS-DH-SP-40 is a single-axis spindle amplifier from the Mitsubishi Electric MDS-DH 400 V-class drive family. Its main power circuit uses a DC link, while a separate AC supply powers the control circuitry. Sine-wave PWM control regulates the motor output, and regenerative braking supports spindle deceleration through the matched drive system. Forced-air cooling removes heat during operation within a suitable control cabinet.

Key Features:

CNC Spindle Control: Operates a compatible spindle motor within a matched Mitsubishi Electric CNC drive system.
DC Main-Circuit Input: Accepts a rated 513–648 VDC supply at 15 A.
Three-Phase Output: Provides a rated 340 VAC motor output at 13 A.
Separate Control Power: Uses an AC control supply independently of the main DC link.
PWM Regulation: Employs sine-wave pulse-width modulation for motor control.
Regenerative Braking: Supports energy recovery during deceleration through compatible system components.
Forced-Air Cooling: Uses fan cooling to dissipate operating heat.

The MDS-DH-SP-40 delivers the reliability and precision required for spindle operation in compatible CNC machining systems.
