Woodward’s ATS (automatic transfer switch) controllers help
you reduce complexity in terms of hardware, spacing, and component cost for new
builds and retrofits. This is feasible, because our configurable software
allows these applications to run from one controller:
Utility-to-Generator
Generator-to-Generator
Utility-to-Utility
This also includes delayed and closed transition
modes, among other typical ATS-specific features. By using Woodward products,
you can handle all ATS-relevant features by ordering one single device, which
provides maximum value for your ATS application. For more simple applications,
Woodward provides a basic version of an ATS controller.
