Description of TOMZN Automatic Voltage Current Protector Socket The TOMZN TOSVA-16 is a smart voltage and current protection device designed to protect electrical appliances from unstable power conditions. It continuously monitors voltage and current and automatically disconnects power when unsafe conditions occur, then restores power when everything returns to normal. Featuring high-conductivity nickel-plated copper for efficient, low-heat power flow, this socket ensures long-lasting durability and rust resistance. To prevent children from accidentally inserting objects into the socket, the safety shutter is designed to open only when a pressure equivalent to 8.5 kg is applied.. It is ideal for homes, offices, laboratories, and industrial electrical systems. Main Features Over-voltage protection Under-voltage protection Over-current protection Automatic power recovery Real-time voltage display Real-time current display Voltage calibration (±9.5% adjustable) Factory reset function Fault history inquiry Specification Parameter Value Model Number TOSVA-16 Power Supply 90–300VAC, 50/60Hz Max Load Current 1–16A (Adjustable, Default 16A) Power Consumption ≤ 2W Mechanical Life 100,000 operations Electrical and Mechanical Life ≥ 100,000 cycles Installation 35mm DIN Rail Socket Type EU Input Voltage AC 190-300V Over-voltage Protection Value 100-300V, Default 270V Over-voltage Recovery Value 95-295V, Default 265V Under-voltage Protection Value 80-210V, Default 170V Under-voltage Recovery Value 85-215V, Default 175V Over-current Protection Value 1-16A, Default 16A Over-current Recovery Value 0.5-15.5A Recovery Delay Time 1-500s, Default 30s Continuous Over Current Faults Times 1-20 times, Default OFF Power-on Delay Time 1-500s, Default 10s Action Time 0.1-30s, Default 1s Boundary Dimension 122×55×86 mm Product Setup The TOMZN TOSVA-16 is an advanced electrical safety device designed to protect your appliances from unstable power conditions by monitoring voltage and current in real-time. It features a highly customizable interface, allowing users to set specific protection limits and recovery times to suit their environment. Below is the detailed Product Setup guide covering all adjustable parameters: Code Function Range A1 Power-on delay time (seconds) 1 – 500s A2 Over-voltage protection value (V) 100 – 300 / OFF A3 Over-voltage recovery value (V) 95 – 295 A4 Over-voltage recovery delay time (seconds) 1 – 500s A5 Over-voltage protection action time (seconds) 0.1 – 30s A6 Under-voltage protection value (V) 80 – 210 / OFF A7 Under-voltage recovery value (V) 85 – 215 A8 Under-voltage recovery delay time (seconds) 1 – 500s A9 Under-voltage protection action time (seconds) 0.1 – 30s A10 Over-current protection value (A) 1 – 16A A11 Over-current recovery delay time (seconds) 1 – 500s A12 Over-current protection action time (seconds) 0.1 – 30s A13 Voltage calibration (%) -9.5 – 9.5% A14 Continuous over-current fault times OFF – 1 – 20 A15 Current calibration (%) -9.5 – 9.5% Instructions: Change the setting value by pressing [Up]/[Down] keys. When the setting over-voltage protection value exceeds 300V, the over-voltage protection function will be closed. When the setting under-voltage protection value is lower than 140V, the under-voltage protection function will be closed. Press the [Up] key for more than 12 seconds to query the last fault, and press the [Down] key for more than 6 seconds to restore the factory settings. During the setting process, it is not necessary to press the last step, but long press the SET key to save.
