Digital Display Variable Voltage Regulator

Physical size: 120 mm (L) × 65 mm (W) × 55 mm (H). Operates on AC 220–250 V input. Delivers fully adjustable AC output from 0 to 220 V. Rated for continuous 2000 W loads (4000 W peak); maximum safe current: 9 A continuous, 15 A instantaneous trip point. EU plug fitted — compatible with outlets in Germany, France, Italy, Spain and Indonesia. Enclosure: High-grade flame-retardant plastic; internal conductors: Phosphor bronze for corrosion resistance and conductivity. Enables accurate, repeatable speed control for angle grinders, blowers, tungsten lamps and electric furnaces by varying supply voltage — not frequency or pulse width. Calibrated knob + digital LED voltage readout ensures users know *exactly* what voltage is delivered, supporting process consistency in fabrication or restoration work. Status LED provides visual confirmation of live operation. Not intended for switch-mode power supplies, inverters, or any device containing PCBs, ICs, capacitors or magnetic coils — e.g., LED lighting, rice cookers, washing machines, water pumps or induction stoves — as these may draw non-sinusoidal current or backfeed, risking regulator failure.
