AC Power Automatic Switch Overview The AC Power Automatic Switch is a compact dual AC power switching module that automatically transfers load between a primary power source and a backup source. It provides reliable, hands switching for small loads up to 10 A, making it suitable for backup power setups and equipment that must remain powered during an outage. Key benefits Automatic failover: Instantly switches from main power to backup power when the primary supply fails, reducing downtime and manual intervention. Wide voltage compatibility: Works with AC input voltages from 85 V to 240 V on both main and backup lines, supporting a broad range of applications and regional power standards. Compact and easy to install: Small footprint lets it fit into tight spaces or equipment enclosures without adding bulk. Reliable construction: PCBbased design for stable operation and consistent switching performance.
