Humming on Low Voltage, 2 Transformers?

crichgatAugust 7, 2008

I bought 2, 3 light low voltage track light sets. [Hampton Bay @ Home Depot]. Each set came with it's own transformer.

The two tracks were joined with a connection.

Did I need to use both transformers when I installed them?

They were installed with 1 transformer and a dimmer and I am getting a loud hum. Thanks

If you use two transformers then you'll need an electrical isolator in the tracks. Basically you don't want two transformers powering the same electrical section of track.

As for dimming, either:

1) You have the wrong dimmer. You have to make sure that your dimmer matches the type of transformer. For example, if it's a magnetic transformer, you need a magnetic low voltage dimmer. Or if it's an electronic transformer, you need an electronic low voltage dimmers.

2) It's just not dimmable. The lower priced/ end transformers generally can't be dimmed without a hum/ buzz.
