The TOMZN TOSVA‑16 Automatic Voltage & Current Protector Socket is a plug‑in protection device designed to safeguard electrical appliances from voltage and current abnormalities. It works with a wide AC supply range (90–300 V AC) and lets you set adjustable over‑voltage, under‑voltage and over‑current protection thresholds. When the input goes outside the safe limits, it cuts power and then automatically restores it once conditions return to normal. The unit also features real‑time voltage and current displays, calibration for accurate readings, and buttons for fault inquiry and factory reset. With a 16 A adjustable load capacity and long service life, it’s ideal for protecting household and office equipment from unstable mains power.
