Automatic Transfer Switch
Panel-level automatic transfer switch for facility and generator failover.
Overview
Product Overview
The Wandtung Automatic Transfer Switch is a panel-level device that automatically transfers a facility or distribution board load between a primary source and a backup source — typically utility and standby generator — without manual intervention, sized for branch, panel or facility-level loads rather than a single rack.

FAQ
Frequently Asked Questions
A panel-level automatic transfer switch handles facility, distribution board or generator-level failover for a whole branch of the electrical system, while an ATS PDU is a rack-mounted device that applies the same automatic-switching principle to a single rack's power feed.
