Anyone see anything wrong with dimming a low voltage landscape light transformer if its hardwired in ?
I believe you want a dimer that 'comes on' at zero and drops out before returning to zeroIf the dimmer and transformer are both listed for the application I see no problem at all.
Incandescents or LEDs doesn't matter. Both will dim nicely with the proper equipment.As long as there are just incandescents connected the transformer, I don't see an issue with it.
Dimming is done on the primary side of the transformer. There are some cases (very rare) where a dimmer or voltage control would be applied at the secondary, but not a common practice.Do they "dim" the circuit before the xfmr or after the xfmr?
I learned this when I tried to put a speed control on my blender....It will work for resistive, but a dimmer designed for resistive loads will cause the transformer (or the dimmer) to fail early, and it'll be noisy.
Used to Haven't installed one in a while so I don't know. This appears to be one.A what? :blink:
I mean yes I know what they are, but I don't think I can get one for a wall switch.
Most likely so you don't have to dissipate all the power on the secondary which is usually a much higher current.If you know the reason for that, would you please share it? Thanks.
triden beat me to it but his answer is correct:If you know the reason for that, would you please share it? Thanks.
LOL and that picture is of an ordinary triac based dimmer with a rotary knob.Used to Haven't installed one in a while so I don't know. This appears to be one.
