Ensure 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.
