When I installed a dimmer on my Monorail System, the transformer started to buzz, what can I do about it? - Ben Hansen , 2009-02-27 15:22:23

Check that you have the correct dimmer switch for the type of transformer you are using (i.e. electronic low voltage dimmer with a electronic transformer, low voltage magnetic dimmer with a magnetic transformer). With magnetic transformers (surface mount or remote) a de-buzzing coil may be added inline between the dimmer and the transformer. An integral de-buzzing coil is included with all of our surface mounted magnetic transformers.
