Try to install an air curtain for a swinging door? The door swings in and out a few times then settle to stop. You must get this circuit kit to avoid the motor to be on and off during the door swinging.
With 2-3 seconds shutoff delay, the air curtain won't shut off immediately when the door isn't fully settled to stop and close in order to protect the motor.
If you have a hard time to install a conventional mechanical plunger micro door switch for your air curtain, please get this circuit kit to convert it to be magnetic switch controlled. Note: not for all models of air curtains. Such as remote controlled, high powered, nor 3 phases power input, etc.
Convert the 120VAC switch controlled air curtain or appliance to be 12VDC magnetic switch controlled.
120VAC 15A max or 1800W max, single phase only.
Not for all models of air curtains, such as remote controlled nor 3 phase high powered, please review it carefully before buying.
