NewTrend · WiFi metering and plug-in protection
Product overview
The OSVA-16LW combines a single protected outlet with WiFi control, voltage/current monitoring, energy metering and adjustable leakage-current protection. It provides overvoltage, undervoltage and overcurrent settings with automatic delayed reconnection. Choose the EU socket or the France version with its protective-earth contact.

Protection and local display
The colour display presents voltage, current and leakage/energy information. Front indicators identify voltage, current, leakage, WiFi and pulse functions. Adjustable thresholds allow the protection settings to match the connected equipment. The leakage setting is 10–99mA, with a 30mA default and an OFF position in the illustrated menu.
WiFi control and energy monitoring
Use Tuya Smart or Smart Life for remote switching and consumption monitoring. The metering interface includes energy use, current, active power, voltage, remaining prepaid energy and residual current. Scheduled on/off and delay functions support automatic equipment operation. The prepaid function and low-credit threshold support energy allowance management.
Front-panel programming
Hold SET for more than three seconds to enter settings. The illustrated sequence covers power-on delay, display interval, overvoltage threshold and recovery, undervoltage threshold and recovery, overcurrent threshold and recovery, repeated overcurrent events, leakage threshold and recovery, repeated leakage events, voltage/current/kW calibration and low-credit warning. Use the up/down keys to adjust the selected value and press SET at End to save and exit.
The setup diagram shows 1–999-second delay menus and 1–30-second voltage/current action menus. Voltage, current and kW calibration span −20% to +20%. The overcurrent and leakage event settings can be OFF or 1–20. The low-credit energy warning can be set from 0 to 50kWh. The power key connects or disconnects the output manually.
EU and France socket versions
The EU version uses the illustrated round-pin plug and side-contact outlet. The France version has the illustrated protective-earth pin in its outlet. Match the selected contacts to the supply and appliance before use.
Dimensions and installation
The illustrated EU enclosure measures 122mm high, 55mm wide and 86mm deep including its plug; the body depth is 45mm. The plug drawing identifies a 35mm plug section, 18mm pin spacing and 37mm projection. Keep the display accessible and the enclosure dry and ventilated. Keep the connected load within the ratings of the socket, plug and supply circuit.
Typical applications
For compatible household and equipment loads requiring remote switching, energy monitoring and adjustable voltage/current protection. Set protection thresholds and reconnection delays to suit the appliance and its starting current. Provide the required upstream circuit and residual-current protection.
