Features 1、Automatic And Manual Operating: The photovoltaic to mains ATS (automatic transfer switch) offers both automatic and manual modes of operating, ensuring seamless power transition. It switches power sources in milliseconds (&lt;50ms) without causing power interruption, thanks to its compact design and stable transfer capabilities. 2、Uninterrupted Power Supply: Designed for scenarios where continuous power is crucial, this mini automatic transfer switch automatically transfers from the primary power source to a backup source in the event of a power anomaly. When the primary power source is restored, it auto switches back, ensuring the continuity, reliability, and safety of the power supply. 3、Easy Installation: The double power automatic transfer switch is suitable for emergency power systems with AC ratings of 63A at either 50 or 60Hz. It is specifically designed for home rail installations, fitting seamlessly into PZ30 distribution boxes with a standard 35mm rail mount, making installation straightforward. 4、Excellent PC Material: Constructed from excellent flame retardant PC material, the double power electrical selector switch has excellent insulation properties and high temperature resisting. The silver contacts resist aging, enhancing safety and reliability while significantly improving conductivity and prolonging the product's lifespan. 5、Wide Applications: Crafted with fine engineering, the power automatic transfer switch is designed for stability with isolation anti interference and self recovery features. It is widely applicable in photovoltaic systems, homes, shopping centers, factories, laboratories, farming industries, and more, providing a robust performance across various environments.
