Automatic Transfer Switches
Our automatic transfer switches provide reliable power switching between primary and backup power sources. These critical components automatically detect power loss and seamlessly transfer electrical loads to alternative power sources, ensuring continuous operation of essential systems. Available in various configurations to meet specific requirements for data centers, healthcare facilities, industrial applications, and commercial buildings.
Open Transition ATS
Break-before-make transfer switches that momentarily disconnect from both power sources during transition. Ideal for most applications where a brief power interruption is acceptable, offering reliable performance and cost-effective design.
Closed Transition ATS
Make-before-break transfer switches that momentarily connect both power sources during transition. Perfect for critical applications requiring zero interruption of power, such as data centers, hospitals, and sensitive industrial processes.
Custom Solutions
Tailored automatic transfer switch systems designed for unique requirements. Our engineering team can develop custom solutions for complex power distribution needs, specialized industries, or unusual installation environments.
