Built-In Electrical Protection for Maximum Safety

Electrical instability can cause serious damage to appliances and wiring. The KWS-302WF includes intelligent protection mechanisms that automatically disconnect power when unsafe conditions are detected:

• Over-voltage protection prevents damage caused by voltage spikes

• Under-voltage protection safeguards equipment during low voltage conditions

• Over-current protection stops excessive current flow to avoid overheating and fire risks

Once conditions return to normal, the device can automatically restore power, ensuring continuous protection without manual intervention. The power-off memory function retains your settings even after an outage.

Wi-Fi Connectivity & Remote Control

Thanks to built-in Wi-Fi support, the KWS-302WF allows you to monitor and control your electrical system anytime, anywhere through a compatible mobile application. From your smartphone, you can:

• View real-time voltage, current, power, and energy usage

• Set protection thresholds for voltage and current

• Turn power ON or OFF remotely

• Track historical energy consumption

• Manage timers up to 999 hours

This makes it an excellent solution for smart homes, remote sites, rental properties, and energy-conscious users who want full visibility and control.
