The buzzing is from a loose winding that is moving. The best way is to throw the unit away and get another unit. The other alternative is to break he unit open and paint the coil.

Can you run 12 volt DC adapter equipment with a 12 volt transformer?

The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.


Can you power a 12 volt dc indicator light from a 16 volt ac door bell transformer?

No, the 12 VDC light must have a DC supply and the transformer voltage as well as being 16 volts which is too high, the output is AC.


I have ten 12 volt 10 watt lights what transformer do you need?

To power ten 12 volt 10 watt lights, you would need a transformer with a total output of at least 120 volts and 100 watts.


What do you do to change the voltage of a 12 volt battery to a 6 volt output?

To change the voltage of a 12-volt battery to a 6-volt output, you can use a voltage regulator or a step-down transformer. A voltage regulator will reduce the voltage to the desired 6 volts, while a step-down transformer will step down the voltage from 12 volts to 6 volts. Both options will help you achieve a stable 6-volt output.


How do you convert 24 volt trailer lights to 12 volt?

To convert 24 volt trailer lights to 12 volt, you will need to install a voltage regulator or resistor in the circuit to reduce the voltage to 12 volts. Alternatively, you can also replace the 24 volt lights with 12 volt lights designed for trailers.

Reduce the primary voltage and the secondary will also drop.


How can you find out if your 12 volt transformer for halogen lighting is dimmable?

Look at it and find its weight. If it is heavy it contains a transformer and is dimmable. If it is very light and obviously contains no transformer, it can't be dimmed.

What is the formula to convert 240 volt to 12 volts?

If it is AC then you don't need a formula, you just need a transformer.


What is the amp rating of 100va transformer?

The amp rating for a 100VA transformer will vary depending on the actual voltage of the transformer. Transformers have both a primary and a secondary voltage.
