    30A LED dimmer will not work for controlling electric throw?

    Hello, When the mosfet was driven from the 5 Volts, it can well be that it is not fully driven and still in the linear region. When in the linear region, the dissipation will be high and the mosfet will heat-up. Bertus

    30A LED dimmer will not work for controlling electric throw?

    Hello, Where did you buy the dimmer? When on alibaba, ebay or aliexpress, they values can well be overrated in the advertisement. I found the page: https://www.calrad.com/92-342-hg What are you using as 12 Volts supply? Does the blanket not have its own temperature regulation? Bertus

    Converting LED output units

    Hello, @Harald Kapp , Not only the emittor should be moved, also the receiver, wich is probably in the box should be moved. This looks quite a challenge to me. Bertus
