Over and under voltage protection with over current safeguards shield your appliances from power fluctuations and fault currents. Adjustable settings for timed power off and screen hibernation customize energy management to suit residential and commercial use, improving usability and efficiency. Wide voltage compatibility with a measurement range of 100-290V supports diverse electrical systems and power supply conditions. Versatile measurement capabilities include current up to 63A, power up to 17KW, and energy up to 9999KWh, providing detailed insights into energy usage. Use scenarios: - In a home environment, protect televisions, computers, routers, and chargers from voltage spikes and sags while using the adjustable off timer to cut idle power. - In a small office or workshop, manage standby energy for tools and lights, using the programmable timer to reduce operating costs. - In regions with unstable mains, monitor and respond to voltage variations while tracking energy consumption for cost control and optimization.
