FilmGrade Flicker-Free LED Dimmer Specs and Wiring
1) What is the switching frequency? Your info suggests 25 kHz, but you have no spec for that on your product page.
2) Is +, -, or neither common to input and output? I am installing it in a fixed installation, where the number of available conductors is limited. Do I need to run both +/- output wires to the load, or can I run the switched output wire to the load, and tap off one of the input wires (whichever is common) as the other conductor?
To answer your questions:
1) The switching frequency for the product is 25 kHz.
2) The output uses a common positive, and the switching occurs on the ground channel. The article and graphic below may provide you with some additional insights on this:
