Working current: 68ma (current after the trigger switch is turned on)
Output control voltage: DC 0-14V, AC 0-125V
Output control current: <11A
Working temperature: -20 ° C to 70 ° C
Working principle: After the device is powered on, the device will delay the output for a period of time.
Second, the working principle of the switch
This switch is the power-on delay open function. When the power supply port is powered on, the switch will time according to the preset time. The switch will not turn on until the time is up. The main function is to avoid damage to the load device, splash screen and abnormal restart in order to avoid the unstable current and voltage of the power supply.
Third, the scope of application
Household switch control - household products such as exhaust fans and heat sinks
Automotive electronic control--navigation, media sound effects, door and window delay lifting, etc.
Industrial Equipment Control--Access Control Equipment Control--Warehouse, Walkway Lighting
Car lights, headlights off, etc.
Fourth, the test method
1. Connect the load circuit at the output port
2, choose the delay time
3. When the power is turned on, the switch will delay after the preselected time and then turn on.
