2000W Adjustable AC Voltage Controller

Measures just 48 mm × 60 mm × 28 mm and features a rugged composite enclosure with internal FR-4 high-temperature circuit board for reliable performance under load. Accepts 220 V AC input and provides smooth, continuous output voltage control from 50 V to 220 V AC. Designed for resistive applications: handles up to 2000 W peak power, with a recommended continuous rating of ≤1000 W at room temperature to maintain thermal integrity and component longevity. Rated for up to 25 A current — critical for stable operation with low-resistance heating elements that draw high inrush or steady-state current. Compatible with incandescent lighting, AC fans, and certain single-phase induction motors — though motor suitability must be verified case-by-case based on starting torque, winding configuration, and load inertia. Uses pure analog rotary control: no digital interface, no firmware, no setup required — just immediate, linear voltage scaling with tactile feedback and repeatable results. Suited for university electronics labs, maker-space thermal experiments, small-batch curing or drying systems, and upgrading older equipment with controllable AC output — provided the connected load falls within defined electrical and mechanical boundaries.
