4000W Electric Tools Speed Controller Switch Portable Voltage Regulator for Grinder

Stepless speed regulation function enables speed regulation for angle grinders, marble machines, exhaust fans, electric heaters, and other power tools and home appliances. It also supports voltage and power regulation for electric heater resistors, motor fans and other devices, and adjusts brightness, temperature and other parameters.ABS flame-retardant housing provides high-temperature resistance, compression resistance, and high insulation properties. It comes with overload and short circuit protections, built-in overload and independent switch to control input and output voltage, replacing boat switch and fuse, and preventing equipment damage caused by overload or short circuit.Equipped with a potentiometer regulator system, which ensures accuracy and stability of voltage regulation. A high-precision voltmeter displays output voltage in real-time, so that users can grasp the working status of the equipment.4000W high power design meets the use of various types of high power devices. A precise potentiometer regulator achieves speed regulation via turning the regulator, with energy saving performance, and practical operation.Compact model, easy to carry. Designed with a hook buckle, which enables operators to hang it on toolkits or tool belts when using angle grinders to improve efficiency.This angle grinder speed controller is a versatile electronic voltage regulator and speed controller.
