Thermistors ptc gwifren aloi gwrthydd cyfernod tymheredd positif ar gyfer gwresogi

Disgrifiad Byr:

Mae gan wifren gwrthiant aloi PTC wrthsefyll canolig a chyfernod temeiddio positif uchel.
Mae wedi defnyddio'n helaeth mewn amryw o wresogyddion. Gall reoli tymheredd a phŵer sdjust yn awtomatig trwy gadw cerrynt cyson a chyfyngu ar gerrynt.
