Smart Auto-Manual Dual Mode & Microcontroller Precision

Automatic Switching: Instantly detects grid failures (L1) and switches to backup power (L2) within seconds using advanced microcontroller technology.

Manual Control: Override automation anytime to manually select L1/L2 power sources via an intuitive interface.

Fully Adjustable Triple-Layer Protection

Pre-Set & Customizable: Factory settings suit most applications, while adjustable thresholds let you fine-tune overvoltage (OV), undervoltage (UV), and overcurrent (OC) protection for specialized needs.

Grid/Generator/Inverter Safeguard: Shields sensitive equipment from surges, drops, and overloads across all power sources.

Real-Time HD LED Monitoring System

4-Status Visual Alerts: Instantly identify grid/generator/inverter activity, voltage stability, and fault codes via color-coded indicators.

Voltage Display: Track live voltage readings (120V/240V) on the built-in screen – no external meters needed.

15-Minute DIN Rail Installation

Tool-Free Mounting: Secures to standard 35mm DIN rails (free rail included). Compact design fits crowded electrical panels.

Relocate Effortlessly: Slide-adjust for flexible positioning in cabinets, RV power centers, or solar setups.

Mission-Critical Reliability for Demanding Sites

Hospital/Data Center Ready: Trusted by commercial buildings, healthcare facilities, and telecom stations for uninterrupted power.

Industrial-Grade Resilience: Operates flawlessly in -22°F to 140°F environments with corrosion-resistant terminals.
