Double Power Automatic Transfer Switch 4P 400V 125A Quick ATS

Double Power Automatic Transfer Switch 4P 400V 125A Quick ATS Description

1、Built in Sign Output: This automatic transfer switch includes a built in open circuit sign output for scheduled standby use and can connect to an external sign indicator, allowing for easy monitoring from outside the equipment cabinet. 2、Millisecond Level Uninterruptible Switching: In the event of a power anomaly, the switch seamlessly transitions to emergency power in milliseconds, ensuring continuous, and safe power supply without any interruptions. 3、Silver Contactor Design for Improved Conductivity: Featuring silver contactors, this automatic power switch enhances electrical conductivity significantly. Made from flame retardant plastic, it also offers excellent insulation properties for added safety. 4、Versatile Application: This switch is suitable for a wide range of environments, effortlessly switching to emergency power at 400V during outages, and returning to the main power when available, suitable for places requiring uninterrupted power, such as factories, shopping malls, and daycare centers. 5、Caution for Installation: The emergency current switch operates within 85%-110 percent of its rated working voltage. If the coil voltage is too low, it may overheat or burn out; features two independent relays with transformer contactors for control.
