Description
UPS Emergency Power Off Battery Switching Inverter Automatic Battery Cutoff Switch Dual Power Auto Transfer Switch
Product Description
The purpose of the dual power automatic transfer switch is to use one way of normal power one way of reserve power. When the normal power supply suddenly fails or the power is cut off, the dual power supply automatic transfer switch is automatically put into the reserve power supply to make the device continue to operate normally. When the normal power supply is normal, it will automatically switch to the normal switch regardless of whether there is any power in the spare. If there is power at both ends,the normal power supply will be the main one.
