Power consumption while the controller is off

Question

Good morning everyone,

I want to put some led lights on home stairs, but im scared for the power consumption.

The fibaro controller is just after the 12/24 VDC adapter so the power supply will be allways connected to the main AC, i need a power supply of 300w for 6m of led lights for the stairs, but this strips will not be on all the time, i want to turn it off with the fibaro controller, my question is, the power supply (300w, 220v) consumes any power while the fibaro rgbw controller is off?

 

Thanks.

Hi,

I have chosen for another solution(cheaper).

Trafo 300 Watt 230/24 Volt

down- and up stairs a 24 V motion sensor/ timer in serie with the LEDS. Prive around 15,- euro/piece.

So if motion is detected light on after x time light off.

I had done it with Fibaro but it was better to use those devices for 240 V.

I should not bother KWh

300 W = .3 kWh if kWH=.20 >>will cost around 7 cents for one hour!

One person 10 times a day up and down, 2 minutes(is long par cycle)

365x10x2x2x.07/60= 17,-  a year.

Succes

  • I thought about it but my idea was to let the led lights turned on  at the sunset but al 10-20% and when a motion sensor detects someone turn it to 100%. I dont know if the power supply consumes while is connected to the main stream but the fibaro controler is turned off. Is the same consumption if the lights are at 100% or at 10%? thats what bothers me.

    hi,

    roughly it will be 10% and 100% in usage

    so if you use 10% x 300 Watt =30 Watt 100% will be 300 Watt

    succes,
