Hi all - planning z-wave module setup for a electrical re-wire in a renovation. Trying to decide between dimmer modules and switch modules in certain switches. But am struggling to understand how dimming range works in practice given the load constraints on dimmer modules.
Let’s assume I am using Fibaro Dimmer 2. Rated 50-200VA (without bypass) or 5-200VA (with bypass). Assume 3-wire wiring at switch. Then are these calculations correct for hypothetical circuits below?
Circuit A: 5x GU10 5W LED spotlights with power factor 0.8 => 30VA draw in total. Assume this would require a bypass module? Consumes 30VA at full power or 5VA at 16% power. Therefore able to dim from 16% brightness to full brightness - pretty much full range?
Circuit B: 1x GU10 5W LED spotlight with power factor 0.8 => 6VA draw. Assume this would require a bypass module? But module would only consume 6VA at full power and therefore even with bypass module in place it would in practice not be dimmable? And in fact it might be better to use a switch module instead?
Circuit C: 5 x 15W B22 LED bulbs (in table lamps) with power factor 0.6 => 125VA draw. Assume would NOT require a bypass module? But without bypass it would only be possible to dim to 40% (50VA)? Could I add a bypass module and dim much further down to 4% (5VA)?
Thanks for all help!
