Precision LED Voltage Controller

Dimensions: 12.5 x 7.5 x 5.5 cm; Weight: 320 g; Input voltage: 220–240 V AC (UK/EU mains); Output voltage range: 0–240 V AC adjustable; Max load: 15 A / 3300 W resistive; Housing: Flame-retardant ABS plastic; Internal contacts: Thickened phosphor bronze; Display: 3-digit LED voltage readout with backlight; Control: Precision rotary voltage-regulating knob; Protection: Automatic cut-off at >15 A instantaneous current; Mounting: Integrated rear hook for tool-bag hanging. This controller delivers precise, stepless AC voltage regulation to adjust speed of universal motors and brightness/heat of resistive loads. The high-accuracy knob enables fine-tuned control down to ±1 V resolution, verified in real time on the clear LED display. Built-in overload and short-circuit protection activates instantly if current exceeds 15 A, safeguarding both the controller and connected equipment. The rugged flame-retardant ABS casing remains stable under prolonged operation, while phosphor bronze internal fittings ensure consistent conductivity and long-term reliability. Ideal for UK/EU workshop tools including electric routers, exhaust fans, angle grinders, bench grinders, marble cutters, blowers and incandescent filament lamps. Not compatible with devices containing PCBs or capacitive electronics — such as LED lights, induction hobs, microwaves, rice cookers, washing machines or water pumps.
