The Autoro AB18 is a DC automatic transfer switch designed for seamless switching between primary and backup power sources. It supports 12V to 60V DC systems and provides up to 18A continuous output, suitable for telecom, industrial automation, security surveillance, and renewable energy applications.
Key Features
1. The AB18 allows custom configuration of switchover and restoration voltages via the front‑panel SET button, enabling precise adjustment for different battery types and load requirements.
2. The switching logic is threshold‑based: the unit transfers to the backup source only when the main voltage drops below the set point and is lower than the backup voltage. It returns to the main source once the main voltage recovers above the restoration threshold. Switching delay is minimal, ensuring uninterrupted operation for sensitive loads.
3. Input paths are isolated to prevent cross‑discharge between main and backup batteries, protecting battery life. A digital display shows real‑time output voltage, and LED indicators (L1 / L2) clearly show which source is active. All connections are made via screw terminals.
Specifications
Input voltage range is 12V to 60V DC, with a maximum continuous output current of 18A. Switching delay is extremely low, with display and LED status indicators provided. Connections are via screw terminals.
Applications
Typical applications include telecom and communication systems (routers, switches, base stations), industrial automation (PLC, DAQ, sensors, motor controllers), security and surveillance (IP cameras, NVR/DVR, access control), renewable energy and backup power systems, marine, or off‑grid DC power management.
