Automatic Transfer Switch (ATS) Single-Phase 63A AC220V Source Inverter with LED Display, Overvoltage and Undervoltage Protection for Mains Inverters and Generators (GPS8-17)

【Automatic Switching】: The automatic transfer switch (ATS) features overvoltage and undervoltage protection. It can connect two power sources and automatically switch between the primary and backup sources. In the event of a failure of the primary source (L1), the ATS automatically switches to the backup source (L2) to ensure continuous operation (switching time: 200 ms). 【Accurate Monitoring】: Equipped with a built-in voltage and current monitoring function, the automatic transfer switch displays the real-time voltage of the primary/backup sources as well as the load current. The LED indicators on the panel provide clear visual feedback on fault status and phase selection, allowing for intuitive monitoring of the device's operation. [Multiple Parameter Settings]: This dual-power switch (priority selection: L1-L2-Auto) is suitable for electrical systems with a rated current of 63A (45/65Hz). The switching time is adjustable from 0 to 900s (default: 0s, corresponding to a minimum actual switching time of approximately 200ms), and the reset time is adjustable from 2 to 900s (default: 10s). These settings offer flexibility to adapt to different equipment power requirements. [Easy Installation]: Thanks to its DIN rail mounting and compact size of 82*72*68 mm, this transfer switch takes up minimal space and can be installed in a standard household electrical panel. Its flame-retardant ABS housing makes it adaptable to complex environments, ensuring stable and reliable operation. 【Wide Range of Applications】: This automatic transfer switch effectively prevents equipment shutdowns due to power outages. It is suitable for various power supply needs, whether for home use, in small technical rooms, or for industrial control systems.
