mama chuttak withara dannawa.ahannako danna deyak nam kiyannam

Mekai machan case eka, ara Automatic Bulb wel thiyenawa neda, eke podi circuit ekak ekka Triac 4n thamai AC current eka OUT karanne. mata denaganna one meke thiyena triac 4 wenuwata wattage eka wedi Triac 4k demmoth 5W bulbs 20k withara connect karaganna pluwan weida. Triac change nokara Direct Connect kaloth weda karanawa, but ikmanata Tric burn wenawa

mehemai,wedi current ekak adinna pulwan triac dewoth wede hari.but ambaneka rath wei.loku heat sink danna.kochchara current eka adinawada?

mehemai,wedi current ekak adinna pulwan triac dewoth wede hari.but ambaneka rath wei.loku heat sink danna.kochchara current eka adinawada?

machan eka line ekakata 100W withara one, Watt gana wedi Triac demmama awulak nethuwa weda karai neda

 

[aruna1]

ow weda karanna ona.dana triac eke datasheet eke balanna max current eka keeyada kiyala

 

[nrjayasinghe]

ow weda karanna ona.dana triac eke datasheet eke balanna max current eka keeyada kiyala

Thanks machan, mama ada test karanawa, result eka kiyannam

machan okata triac wenuwata 5A-10A relay 4k dapan kisi awlak na niyamata weda karai. ehema nethnam ampiarage eka wediyen adinna puluwan triac dapan hodama krame relay dana eka.

ow ekath hodai but ethakota size eka loku wenawa ne.but wede easy rath wenneth ne

Triak 2k Parallel karala danna

current rating eka wadi Traics use kala nam hari. eth high-current Traics walata me circuit eke gate drive madi wei de danna. ehema unoth hariyata wada karanne na. nathinam wadiyen heat wenawa.

Relay danna nam ekko 220V AC coil thiyena relay use karanna one (expensive)
12V eva use karanawa nam, circuit eka modify karanna one + 12V power supply one.

relay dammoth dimming karannath ba.

Me wedeta Relay Hariyanne ne machan, Relay kiyanne ON / OFF switch ekak witharai ne. eken light Dimm karanna be, Bulb wel wala thiyena Circuit eke light wala Brightness eka adu wedi weem thiyenawa, ithin ekata haeiyanne TRIAC witharai

Yes machan, me weden mama balaporoththu wena pradanama de thamai dimming

 

[aruna1]

Yes machan, me weden mama balaporoththu wena pradanama de thamaidimming

ah ehenam relay be.triac ma thamai

(PWM use karanawanam relay walin dim karanna puluwan,but mara electrical interfierence ekak generate wenawa + relay eka tika welawakin ma kela wenawa)
