Automatic Transfer Switch for Dual Power Systems, 6A–63A

Keep essential equipment running when the main supply drops. This automatic transfer switch shifts power from A to B so your system stays active with less interruption.

It is built for AC 50–60Hz systems and rated currents from 6A to 63A, giving you a practical solution for dual-source power management.

Stay Powered When the Main Supply Fails

✅ Automatically switches to backup power when the main source becomes unavailable

✅ Keeps work and home systems running through unexpected outages

✅ Rapid response under 75 milliseconds reduces downtime

✅ Defaults to Power A when both sources are active for efficient operation

✅ Supports consistent power flow to reduce stress from unstable supply changes

✅ Offers manual and automatic modes for control during inspection or maintenance

✅ Fits standard DIN rail setups for cleaner installation in supported applications

In daily use, the selector stays in electric mode for normal operation. When Power A is lost, the unit moves to Power B automatically, so your setup keeps moving without a long wait.

That makes it useful for residential, commercial, and generator-supported systems where continuity matters. The two-station layout keeps the switching logic simple: Power A is the primary source, and Power B takes over when needed.

The manual mode is there for inspection or maintenance, and it should only be used when all power sources have been safely disconnected. Once the task is done, switching back to automatic mode returns the control circuit to normal operation.

Its relay-based control and reliable dual-source handling create a steadier power experience for sensitive equipment and everyday electrical stability.

Keep your power flow steady with automatic switching that supports uninterrupted operation.
