WK611 PWM Speed Controller – 0‑110 V DC Output (110‑220 V AC Input, 6 A)

The WK611 is a PWM-based DC motor speed regulator that efficiently converts 110 V–220 V AC input into a controllable 0–110 V DC output, delivering up to 6 A. Designed for precise speed control of spindle or other DC motors, it’s suitable for diverse applications—ranging from CNC spindles to DIY electronics requiring smooth variable motor control.

Key Features:

• Wide AC input range: 110 V–220 V compatible for global use
• Adjustable 0–110 V DC output for flexible motor control
• Maximum output current of 6 A supports a range of motor sizes
• PWM control ensures high efficiency and reduced motor wear
• Integrated digital display shows real-time voltage and current
• Ideal for speed control of brushed DC motors in fans, pumps, conveyors, etc.
