4000W EU Plug Voltage Adjustment Switch

Unit size: 120 mm length × 65 mm width × 55 mm height. Designed for AC 220–250 V input — matches nominal EU grid voltage. Output voltage is continuously variable from 0 to 220 V AC. Supports maximum load of 4000 W (peak, resistive), with 2000 W advised for continuous-duty applications. Electrical limits: 15 A maximum instantaneous current, 9 A continuous. Outer casing: high-temperature-resistant, flame-retardant plastic — does not yellow, warp or crack under normal workshop operating temperatures. Internal conductors: thickened phosphor bronze — selected for durability, low contact resistance and resistance to fretting corrosion. Voltage setting controlled via high-resolution rotary knob; digital LED screen displays actual output voltage with ±1 V accuracy. Operational status indicated by illuminated LED. Dedicated toggle switch provides complete power isolation. Overload protection circuit interrupts supply instantly if current exceeds 15 A. Validated for use with angle grinders, exhaust fans, incandescent lighting, electric furnaces, marble cutting machines and air blowers. Not compatible with appliances containing printed circuit boards, capacitors or semiconductor controls — such as LED lamps, microwaves, induction hobs, rice cookers, submersible pumps or domestic laundry equipment.
