No, an AC dimmer switch is designed to work with AC-powered devices, not DC. DC fans require a different type of dimmer switch specifically rated for DC power. Using an AC dimmer switch on a DC fan can potentially damage the fan or the switch itself.

Can you use a dimmer switch on a very small AC motor?

No, dimmer switches are not suitable for use with small AC motors. Dimmer switches are designed for use with incandescent or LED lights and may not provide the necessary control or protection for a motor. It is recommended to use a motor speed controller designed specifically for small AC motors.


What is a LDR dependent AC dimmer?

The LDR dependent AC dimmer is a Light Dependent Resistor which works by chopping off the parts of the AC voltage.


Can you put an AC dimmer switch on a low voltage 12 volt halogen light fixture?

Although a dimmer can be designed for 12 v halogen lamps it is more common for dimmers to work on higher voltages. Dimmers have to work into a resistive load so it is not usually possible to place the dimmer on the high-voltage side of the 12 v transformer that comes with the lights.


Why does a dimmable eco bulb not dim when controlled from a dimmer switch?

The bulb must be labeled as dimmable. If the bulb is an LED for example there is a circuit that transforms the 120 AC supply voltage to a DC voltage. This circuit needs to be able to supply a DC voltage proportional to the voltage required to operate the LEDs. In a dimmable bulb you might be powering the multiple LEDs selectively to achieve dimming rather than just reducing voltage to all LEDs over a very small voltage range in which an LED operates.


Can a 220 volts ac fan run in a 12 volts battery?

No, a 220 volts AC fan cannot run directly from a 12 volts battery. The fan requires a much higher voltage to operate efficiently. You would need a power inverter to convert the 12 volts from the battery to 220 volts AC to power the fan.

Is there a 120 AC dimmer switch wiring diagram for 24 volt DC motor?

The output of a 120 volt dimmer switch will be an AC voltage so should not be used on a DC motor.

Why is my AC motor not getting any power?

If you mean the compressor, then it could be: A blown fuse, bad AC switch, or low freon. If you mean the blower fan, same problems above, but add a bad fan switch, or regulator.


If the ac gas have low presure then radiator fan doesnot work without ac?

Generally, on most vehicles, the radiator fan is controlled by a thermostatic/electric switch. When the coolant temperature rises to the setpoint, the switch closes, applying electric current to the fan, turning it on. Then, when the coolant temprature has cooled below the setpoint, the switch opens, turnng the fan off.


Why would the condenser fan fuse blow out every time you turn on the AC in an Acura Integra?

You have a short in the wiring or switch. Use either an ohm or multi meter to trace it out. Start at the switch and work back toward the fan fuse connection.
