<P><SPAN class=RVTS8>Badam nad tim protoze to chci pouzit, to je snad jasne. Nevim ze bych uvadel nejaky teplotni rozsah. ten drat neni 2mm ale 2mm2. Pro 0,01R mi vychazi delka cca 1,5cm a ztratovy vykon 4W. Neprijde mi to jako extremne moc, ale nevim jake to vyvola ohrati dratu. Zkusit to nemuzu, jednoduse proto ze 20A zdroj nemam a veset to nekam na trafo nechci bez toho abych to mel napred overene vypoctem a proto se ptam. Letovat ho nechci, mel by prijit do droubovaci svorkovnice. </SPAN></P>

<P><SPAN class=RVTS11>Nevim co badate nad povolenym proudovym zatizenim, to bude u Kanthalu tezko uvadene pro vas teplotni rozsah, Kanthal snasi teploty pres 1200C.</SPAN></P>
<P><SPAN class=RVTS11>Asi nejrychlejsi bude experiment, ale jednoduchym vypoctem me vychazi pro 2mm drat cca 20W/100mm pri 20A, to bude na mereni trochu velke otepleni :o)</SPAN></P>
<P><SPAN class=RVTS11>Staci tedy vzit regulovany zdroj a zmerit proud pro primerene otepleni, na ten 10mR bocnik bych to tipoval na 2x 40mm, nebo 3x60mm toho 2mm dratu.</SPAN></P>
<P><SPAN class=RVTS11>Kanthal ma take velke termonapeti ve styku s medi a neda se dobre letovat.</SPAN></P>
