occkic | 2 Channel Automatic Power Switch Module AC90-220V 30A Dual Input Power-off Switcher Transfer Board Emergency Backup Power Supply

Feature:1. Supports AC 90-220V wide voltage input, compatible with various power supply devices.2. Capable of carrying up to 30A of current, suitable for the usage requirements of high-power electrical appliances.3. Adopting dual power input design, achieving uninterrupted power supply and ensuring electrical safety.4. Automatically switches to the backup power source during power outage, with quick response and simple operation.5. Compact emergency power-off protection module, easy to install, suitable for various scenarios. Overview:The function of the dual-power 220V automatic transfer switch module is to achieve automatic switching between two power sources. The main power terminal is connected to the regular main power supply, and the auxiliary power terminal is connected to the backup power supply. The output power voltage is equal to the input power voltage. When the main power supply does not have voltage output, the module automatically switches to the backup power supply for output. When the main power supply resumes power supply, the module automatically switches back to the main power supply for output. Parameters:Input voltage: AC 90 - 220VOutput current: Maximum 30ATwo power supplies automatically switch, with only milliseconds of interval in between Usage Introduction:Connect the main and auxiliary voltages, and the output is connected to the load.Usually, the main power supply is used (it is preferred). When the main power supply runs out of power, the backup power supply immediately takes over. Once the main power supply is restored, it automatically switches back.
