Betapack 2 led dimming

[Johan94]

Hello,

In our building (restaurant and meeting center) we have five betapack 2's for the dimming of all the lighting. We're planning to move to leds though. Can we dim (philips) leds with the betapack 2's? Considering in most cases there are more than 10 lights per channel.

Considering the pdf file in this link (https://www.philips.nl/c-dam/b2c/category-pages/lighting/generic-lighting-pages/led-pages/dimmable-led/led-dimmer list-bulbs and spots.pdf) for dimmer compatibility, would you say (most) philip leds would with the betapack 2's would work? 

Cheers,

Johan

Hi Johan,

The Betapack 2 is a leading edge Triac dimmer. Looking through that PDF there is no mention whether those lamps will be happy on leading edge dimming, so you would have to try at your own risk.

You say you will plug multiple LEDs into a single channel, so you should be over the minimum load of 0.1A. Therefore it may be worth buying a small batch and trying them on a channel, to see whether the dimming curve is acceptable.

Thanks for the answer, we will just try it then!

Another related question: if the the channel is always on 100% (so never any dimming), can we then connect non-dimmeble leds to the betapack?

Hi Johan,

It isn't recommended, as although the channel is at full, the Triacs are still in circuit, and so cause the AC Sine wave to become very messy, which capactive dropper power supplies such as in most LED lamps don't like!
