Important Notes
- This controller reduces voltage — it does not boost voltage. It is not suitable for applications requiring very precise or very low-speed control.
- Not compatible with smart appliances containing circuit boards, LED energy-saving lamps, induction cookers, rice cookers, household water pumps, or washing machines.
- For indoor use only in dry environments. Keep away from water splashes, fire sources, and out of reach of children.
- If the motor already has gears or high/low-speed cables, a buzzing AC frequency sound may occur or the controller may have no effect.
Package Includes
