Hello,
I would to be sure : is there any power consumption when dimmer is set to OFF (and/or 0%) on the 230V side (not the 12-18V DC from the module) ?
Thanks
PS : by the way, is there a curve or “abaque” about 230V power consumption with dimmer % (ie. 50% for a 100W lamps will be equivalent to 80W) ? …
Hi Golfy,
Normally there is no power consumption when the dimmer is off.
The consumption of power by the dimmer depends on what kind of dimmer you have. A PWM dimmer consumps less power then the normal dimmer. The lost of power of a normal dimmer (zero cross dimmer) is only when the dimmer is conducting (between 0° – 180° and 180 – 360°) so the time of conducting and the voltage over the triac and the current flowing in the triac makes the power lost.
If you search the internet you will find some formula’s to calculate the losses
golfy,
go to the following site sound.westhost.com/lamps/dimmers.html
maybe this will help you.
