The 140A Intelligent Blue Voltage Digital Battery Switch (Model: WNB015) is a dual-battery isolator controller with a digital voltage display, designed for RVs, yachts, and various vehicles. Operating at DC 12-24V, it has a current rating of 120-140 Amps, providing reliable power protection and intelligent battery management.

It features both manual and auto modes: long press the button for 3 seconds to turn on manual mode (blue LED on), pressing the button to switch circuit on (red indicator and voltmeter on) or off (both off). Long press again to activate auto mode (blue LED off), which connects circuits automatically when voltage exceeds 13.3V and disconnects when below 12.7V.

Equipped with a real-time digital voltmeter, it displays the higher voltage when two batteries are connected. It has pressure protection, automatically disconnecting circuits if input voltage is below 11V or above 17V to prevent main battery over-discharge.

Constructed with copper contact material and screw terminals, it has a compact size of 66.5*66.5*52.2mm and 6mm screw diameter for easy installation. With an IP65 waterproof rating, it adapts to harsh marine and outdoor environments.

Widely compatible with trucks, UTVs/ATVs, boats, marine vessels, buses, etc., it ensures the main battery stays charged and avoids drainage. This switch integrates intelligence, safety, and convenience, making it ideal for dual-battery system control.
