Trailing Edge or Leading Edge

Question:

Which mode (trailing edge or leading edge) of my dimmer switch do I have to use for my installation?

Answer:

Depending on the chosen mains dimmable driver, the dimmer switch needs to function in either trailing edge or leading edge (triac) mode.

For the Hi-Line low power mains dimming driver (i.e. 12W, 20W, 30W and 60W) a trailing edge dimmer is required.
For the Hi-Line high power mains dimming drivers (i.e. 100W, 150W and 200W) a leading edge (triac) dimmer is required.

A suggested mains dimmer to use with the Hi-Line mains dimming drivers is the Varilight V-Pro dimmer.

This dimmer works on 3 different modes (trailing edge mode, leading edge mode and an alternative trailing edge mode).
