Description

1.Description:

 It is a dual power automatic switch.Its function is to realize the automatic switching of two-way power supply.The main power supply is connected to the common main power supply,and the secondary power supply is connected to the standby power supply.The output power supply voltage is equal to the input power supply voltage.When the main power supply has no voltage output,the module automatically converts to the standby power supply output.When the power supply is restored,the module will automatically switch to the main power output.

2.Feature:

 1).It responds quickly and has short switching times.

 2).It has simple structure and convenient wiring.

 3).It has a main power indicator,which can be used to see the working status of the module.

3.Parameter:

 1).Product Name:Dual Power Automatic Switch

 2).Main Power Input Voltage:DC 7V-30V

 3).Auxiliary Power Input Voltage:DC 7V-30V

 4).Output Load:10A(Max)

 5).Work Temperature:-25℃~85℃

 6).Work Humidity:5%~95%RH

 7).Size:42*29*22mm

4.Instructions for Use:

 1).When the main power supply is powered on,the secondary power supply is not connected,and the main power supply outputs power.

 2).When the main power supply is cut off,the auxiliary power supply is automatically turned on and powered by the auxiliary power supply output.

 3).When the main power supply supplies power again,the auxiliary power supply is automatically cut off,and the main power supply outputs power again.

5.Note:

 1).Mains and negative supply voltages need to be consistent.

6.Usage Scenarios:

 1).Electrical appliances that require constant power supply,temperature monitors for farms.

7.Package:

 1).1pc Dual Power Automatic Switch
