Autoro AB18 Dual Power Automatic Transfer Switch (ATS) – Professional Seamless DC Power Switching for Critical SystemsEnsure absolute, uninterrupted power for your most vital equipment with the Autoro AB18 Automatic Transfer Switch. This professional-grade ATS is engineered to provide flawless, automatic changeover between primary and backup DC power sources. It is the definitive solution for applications where power downtime is unacceptable, delivering reliable, uninterrupted power supply (UPS) functionality for telecom infrastructure, industrial automation, security systems, and renewable energy setups.Take Complete Control of Your Power Backup The AB18 puts intelligent power management in your hands. Unlike basic switches, it allows you to custom-program the exact voltage thresholds for switching. Using the intuitive front-panel SET button, you can easily configure both the cut-off and restoration voltages. This precise DC power management lets you tailor protection to your specific batteries and load requirements, preventing damage from low voltage and avoiding unstable operation. It acts as a smart voltage-sensitive relay and low voltage cut-off protector.Engineered for Reliability & Seamless Performance Our advanced switching logic ensures transparent operation. The unit automatically switches to the backup battery only when the main power voltage drops below your set point AND is lower than the backup source voltage. It returns to main power once voltage recovers above your restoration threshold. This process happens with extremely low delay, providing seamless switching that your sensitive electronics won't even detect. Isolated input paths act as a reliable battery isolator, preventing your main and backup batteries from discharging into each other, a crucial feature for battery protection and longevity.Built Robust for Demanding Applications Designed to perform in diverse environments, the AB18 supports a wide voltage input range from 12V to 60V DC, making it compatible with 12V, 24V, 36V, 48V, and 60V systems. It delivers a high current output of up to 18A maximum continuous current, robust enough to handle significant loads in communication base stations, industrial control panels, or security setups.Clear Monitoring and Simple Installation Stay informed with real-time system status. The bright digital voltage display shows current output voltage, while the L1 and L2 LED indicators provide instant visual confirmation of the active power source (main or backup). Installation is straightforward with all connections made via secure screw terminal blocks for convenient wiring. The compact design allows for easy integration into existing cabinets, panels, or enclosures.Why Choose the Autoro AB18 ATS?Flexible Settings: Customize cut-off and restoration voltages via a button for different scenarios.Fast, Seamless Switching: Extremely low delay ensures zero interruption to connected loads.True Battery Protection: Isolated paths prevent batteries from discharging into each other.Wide Voltage Compatibility: Works with 12V, 24V, 36V, 48V, and 60V DC systems.High-Current Capacity: Supports up to 18A continuous output for power-hungry devices.User-Friendly Interface: Digital display and LED indicators for clear monitoring.Versatile Applications Ready: This automatic changeover switch is the ideal power transfer solution for:Communication & Telecom Systems: Uninterrupted power supply for cell towers, base stations, routers, network switches, and fiber optic transceivers.Industrial Automation & Control: Backup power for PLC controllers, data acquisition (DAQ) modules, sensor networks, motor controllers, and HMI panels.Security & Surveillance Infrastructure: Fail-safe power for IP camera systems, NVRs/DVRs, access control panels, and alarm systems.Solar Panel Systems: Reliable backup switching between battery banks and solar charge controllers for off-grid and hybrid DC power setups.Mobile & Marine Applications: Reliable DC dual power switch and battery isolator for RV power systems, marine electronics, and off-grid vehicles.Pay attention to the Current and Voltage when selecting the correct ATS: Always verify that your main and backup power sources are within the AB18's 12V–60V DC input range and that your continuous load does not exceed 18A.
