• LCD Real‑Time Voltage Display with Low‑Power Backlight: Monitor your home’s single‑phase voltage instantly on a clear LCD screen. The energy‑saving backlight keeps power draw low while allowing easy reading even in dark electrical panels – ideal for daily voltage checks and household electrical safety.
• Adjustable Over‑Voltage & Under‑Voltage Protection: Protect your appliances from unstable grid voltage. Freely set the over‑voltage trip point (111V–150V or OFF) and under‑voltage trip point (80V–109V or OFF), plus independent recovery values and action times. The protector automatically cuts power when voltage goes out of range, then reconnects when voltage normalizes – suitable for residential panel entry lines and home voltage regulation.
• Customizable Delay & Auto‑Reset Modes: Adjust the fault recovery delay (2–10s) and power‑on delay (2–120s) to avoid frequent relay cycling. Choose between automatic reset (voltage returns to safe range) or manual reset mode. This gives you flexible control and enhances stability for single‑phase equipment protection – great for AC 120V household circuits.
• Fault History Inquiry & Factory Reset: Quickly troubleshoot by checking the last fault record (over‑voltage, under‑voltage, or over‑current). With a few clicks you can also restore all settings to factory defaults. Ideal for home energy management and easy maintenance without complicated tools.
