Autoro AB20 Dual Power Automatic Transfer Switch ATS 0-Delay IN DC 5V-30V/60V，OUT 10A/20A Auto Switch for Solar Panel/Surveillance System/Off-Grid/Emergency Backup Systems (AB20D 60V/20A/Display)

AB20 Series Dual Power Automatic Transfer Switch (ATS) - Zero-Delay Power SwitchingThe Autoro AB20 Series Dual Power Automatic Transfer Switch (ATS) is an advanced family of automatic transfer switches engineered for uninterrupted power supply in critical applications. With zero-delay switching, these DC 5V-30V/60V units instantly detect and select the higher-voltage input between two DC power sources—such as solar panels, batteries, or generators—ensuring continuous operation for off-grid setups, emergency systems, and smart appliances. Their robust control module integrates reverse current protection and dual-source output to handle high-demand loads. Compact and built for durability, they simplify installation with screw terminals, making them perfect for DIY projects and professional use. Key Features & Core Technology Zero-Delay Automatic Switching: Instant power transition between dual inputs (e.g., grid/battery, solar/adapter) with no interruption. This auto transfer prioritizes the higher-voltage source and enables simultaneous dual-battery discharge. Wide Voltage & High Power: Supports 5V–30V/60V DC input and up to 20A per channel. Compatible with 12V / 24V / 48V systems for inverter setups, emergency backup, and generators. Built-in Safety Protection: Integrated diodes prevent backflow, ensuring electrical isolation. The overload-safe control module is built for emergency scenarios. Real-Time Digital Display (Select Models): The digital display version shows real-time voltage and status—perfect for smart power management. Easy & Professional Installation: Screw terminal interfaces and DIN rail mounting suit both DIY enthusiasts and professional grid controller cabinets.
