Ruth's sister SK1248 12A 0-48VDC 220VAC PWM internal power cable

SKU CH-4CXB-4ZEFD

Supplies PWM speed control for DC spindle motors from 220 VAC input to 0–48 VDC at 12 A

  • 12 A output drives demanding DC spindle motors
  • 0-48 VDC adjustable range suits variable speed tasks
  • 220 VAC input connects directly to mains supply
  • PWM control enables precise motor speed regulation

SK1248 12A PWM Power Supply

The SK1248 is an internal power supply module that converts 220VAC mains input into a 0-48VDC adjustable output rated at 12A. It uses PWM speed regulation to control DC spindle motors in industrial or custom automation equipment. The unit is designed for integration inside enclosures where variable motor speed is required. New condition ensures full operational life from installation.

For DC motor speed control builds

This module suits builders who need a self-contained 220VAC to 48VDC converter with integrated PWM motor drive capability. It is not for users who require an ATX-form-factor PSU for standard PC motherboards. Buyers needing isolated low-voltage logic outputs or closed-loop encoder feedback should look at dedicated motion controllers instead.
