Late to reply (sorry) but that makes sense. Something I could probably build even if I couldn't find the box, but curious - it may sound silly, but how do you then adjust the filter amounts? It looked like some of these heads required a separate control thinger?Originally Posted by ic-racer
The 412-021 is the Standard Power Supply and is the most economical solution. It is basically just a transformer in a box. Although the ELC lamp is a 24 volt lamp, it is my understanding that the transformer actually supplies 22.5 Volts to give a longer lamp life.
The fan and panel lamp operate on 120V, so the 120V is just passed through.
There are no other electrical or electronic components in the box with transformer.
