CDMALL AC Motor Speed Controller for Brushed Motors – 120V 15A, 6 ft Cord, Variable Speed Dial

Overview

Take precise control of your AC brushed motor with the CDMALL AC Motor Speed Controller. It safely reduces output voltage from 0 to 120V, delivering smooth, stepless adjustment across the full speed range. An extra-long 6-foot cord keeps outlets and devices within easy reach, while a compact profile helps it fit into tight spaces such as attics, grow tents, or tool stations.

This controller is a versatile companion for inline duct fans, exhaust fans in grow rooms, ceiling fans with AC brushed motors, and compatible power tools. It offers an approachable way to dial in just the right speed for ventilation, lighting, or heating tasks without swapping components.

Key Benefits

• 0–120V variable control enables smooth speed ramping across the full range
• Three-position switch plus stepless speed dial for quick or precise adjustments
• 6 ft grounded cord provides flexible installation around corners, attics, crawl spaces, or workshops
• Built-in fuse protection helps guard connected equipment against short-term surges

Ideal Uses

• Inline duct fans and exhaust fans in grow rooms, workshops, kitchens, and bathrooms
• Ceiling fans with AC brushed motors
• Power tools such as angle grinders, electric drills, and routers
• Incandescent and halogen lamps for dimming control
• Resistance heaters and soldering irons for moderated temperature handling

Important Compatibility and Safety

• Designed ONLY for AC brushed motors; not compatible with brushless or DC motors
• Not suitable for appliances with electronic circuit boards (e.g., microwaves, rice cookers, LED lights)
• For optimal performance, use with devices rated 50W and above; devices under 35W may have limited range
• In the event of overload, the built-in fuse will blow; replace with a standard 120V 15A glass fuse

Durability and Design

• Flame-retardant ABS housing resists heat, cracking, and deformation
• Thickened internal contacts provide reliable connections for long-lasting use
• Compact dimensions (approximately 6.5" x 4.8" x 3") fit neatly in tight setups

How It Works

The controller lowers output voltage to regulate motor speed. In Variable mode, the dial delivers a smooth, stepless adjustment; in Full mode, you get full voltage for maximum speed. The 3-way switch makes mode selection fast and intuitive for any experience level.
