Smart Protection With Auto Recovery Realtime voltage and current monitoring automatically cuts power during over/under voltage or overcurrent events, restoring supply when conditions to normal. This protects home electrical systems and connected devices from damage and unexpected downtime. Voltage Current Settings There are set overvoltage (130V–300V) and undervoltage (80V–210V) thresholds with current limits for electrical management. MultiFunction LCD Display Toggle between readings for voltage, current, frequency, and power with clear realtime data on the LCD screen. Red and green indicators provide immediate status cues, and a dimming mode supports energyefficient viewing. Environment Resistant Design Built to withstand extreme temperatures and harsh environments. Mounts on standard 35mm rails and supports both manual and auto recovery with lockable settings. Use scenarios Home electronics protection: In homes with sensitive devices such as computers, NAS systems, TVs, and gaming consoles, this unit monitors voltage in real time and automatically interrupts power during abnormal events, then restores when normal, reducing the risk of damage and downtime. Small office or workshop reliability: Protect printers, routers, workstations, and other essential equipment. Renewable energy and backup setups: When used with solar inverters or generators, the device helps manage voltage fluctuations and provides safe auto recovery when stable voltage returns.
