Features For Emergency Battery Switching: This controller is used for emergency battery switching; when the main power terminal has power, it is connected to the main power supply; otherwise, it will automatically switch to the backup power supply. Convenient Wiring: The automatic switcher module can automatically switch back to the main power supply when the power supply is restored. It is designed with a screw terminal interface for easy wiring. Wide Application: Two-way power supply automatic switcher is widely used in incubator and network power control to realize uninterrupted power supply. Stable and Reliable: The automatic power switch adopts precision manufacturing technology and sensitive components, and has a stable and reliable structure. The output voltage is usually the same as the input voltage. Easy to Operate: The power switching module is manufactured in strict accordance with the standard, with reliability and high accuracy, small size, light weight, easy to operate and easy to install. Features: 1.This controller is used for emergency battery switching; when there is power on main power source terminal, it will connect to main power as power supply; otherwise, it will automatically switch to backup power source. 2.It can automatically switch back to main power source when the power is back. 3.Designed with screw terminals for convenient wire connection. 4.Output voltage is the same as input voltage normally. 5.Widely used for controlling power supply of incubator, network to achieve uninterrupted power supply.
