Comprehensive Protection, Customizable Settings:This device protects against over-voltage, under-voltage, and over-current all in one unit. Both voltage limits (over/under) and the current limit are independently adjustable via clearly marked dials on the front panel—no programming or complex setup needed.
Adjustable Voltage & Current Thresholds:Easily set your desired over-voltage (130-185V AC), under-voltage (80-105V AC), and over-current (1–63A) protection values. Support 110V 120V 220V 230V system.Perfect for matching the exact requirements of different appliances, from sensitive electronics to heavy-duty pumps.
Auto-Reclosing & Intelligent Delay:After a voltage fault clears, the unit automatically reconnects the load after an adjustable delay (5–60s), protecting your equipment from rapid on/off cycling. An LED display shows real-time voltage, current, and fault status at a glance.
Universal Application:Ideal for safeguarding home appliances (refrigerators, air conditioners), solar inverters, generators, RV power systems, and industrial control panels. Protects against both grid voltage fluctuations and equipment-level overloads—one device, multiple layers of defense.
Easy Installation & Reliable Build:Compact DIN rail mount design fits standard distribution boxes. Internal tinned copper conductors and flame-retardant housing ensure long-term reliability. We include a clear wiring diagram and quick-start guide, with 24/7 technical support available via Amazon messages.
