AC Motor Speed Controller, 120V 15A Speed Regulator for Brushed Motors

Key features

• POWER RATINGS & COMPATIBILITY: 110‑120V AC, peak 15A, rated 8A continuous. Resistive loads up to 1800W. Inductive loads (brushed motors) up to 1500W. For brushed motors only – not for brushless, DC, induction, or circuit‑board devices. Motor startup current can be 4-7 times rated current and may trip the 15A breaker; reduce load if needed
• LED VOLTAGE DISPLAY: Turn the dial; the LED meter shows output voltage from 0‑120V. Each setting shows a clear number. After finding a preferred speed for your router, drill, or duct fan, note the voltage shown for later reference
• RESETTABLE OVERLOAD PROTECTION: A 15A circuit breaker cuts power when current exceeds 15A. Flip the reset switch to restore power – no fuses to replace. The ABS shell covers internal components
• COMPACT DESIGN: Measures 5.5 x 2.4 x 2.25 inches with a 3‑ft grounded power cord. Internal contacts support long‑term use. The control knob allows 0‑100% adjustment
• READY TO USE: Comes with a grounded 3‑prong plug that fits Type A and B outlets. A back clip attaches to a belt or tool bag. Plug in, clip on, and operate

This AC motor speed controller is for brushed AC motors only. It changes output voltage from 0-120V to adjust motor speed, light brightness, or heater temperature. The LED display shows the current voltage setting. The resettable 15A circuit breaker automatically interrupts power during overload – no fuse replacement needed. Size: 5.5 x 2.4 x 2.25 inches, with a 3-ft power cord and a belt clip. Standard US socket is designed for grounded 3-prong plugs (Type A & B outlets). Works with: Inline duct fans, exhaust fans, routers, drills, angle grinders, polishing machines, incandescent lamps, and resistance heaters. Note: Minimum recommended load: 60W. Some motors may produce a humming sound at low speeds – this is a common characteristic of this type of regulator. If adjustment range appears narrow (only on/off), the connected load may be too small; try a load of at least 60W. Troubleshooting: If the controller does not adjust speed, check that the internal potentiometer connector is fully seated (transportation can loosen it). Do not use with: Brushless motors, DC motors, induction motors, capacitor-run motors, or any device with electronic control boards (e.g. smart appliances,
