Angle Grinder Speed Controller 4000W EU

Dimensions: 120 × 65 × 55 mm. Max power rating: 4000W (recommended continuous load: 2000W). Input voltage: AC 220–250V; output voltage: continuously adjustable from 0 to 220V AC with ±1V control precision. Equipped with digital LED-backlit voltage display and precision voltage adjustment knob. Housing made of flame-retardant, heat-resistant, non-discoloring plastic; internal conductive parts use thickened phosphor bronze for durability and safety. Features independent power switch, built-in overload and short-circuit protection — automatically cuts off power if instantaneous current exceeds 15A (rated max current: 15A, recommended load current: 9A). EU plug compatible with Germany, France, Spain, Italy, Indonesia and other Type F/C/E countries. Designed for resistive and inductive loads only: suitable for angle grinders, exhaust fans, tungsten filament lamps, electric furnaces, marble machines and blowers. Not compatible with devices containing electronic circuitry — including microwave ovens, induction hobs, rice cookers, water pumps, washing machines, LED lighting or any capacitive or PCB-based appliances. Use case examples: enables precise RPM control on angle grinders for safer metal or stone grinding; allows dimming of incandescent bulbs without flicker; provides stable low-voltage heating control for small electric furnaces; regulates airflow on industrial blowers without motor damage.
