Hi
I've installed some 12V halogen lights in some shelves, such that I have to mount the transformer remotely. I used 3m of normal 1.5mm^2 lighting cable to connect the transformer to the lights, having calculated a
300mV drop across the cable (30mV/A/m x 3.3A x 3m)However in practise I'm losing around 6V in the cable, and have discovered that the transformer output is 125kHz, not 50Hz, explaining the bad attenuation in the cable
So my question is - do all compact dimmable 12V transformers have high frequency outputs?
I don't have space for an old-fashioned 50Hz transformer
Cheers
