Tirohanga
He arai haumaru wehe i te taha rapu: PHD-12TF-288, te whakaurunga mamati me te whakaputanga, te whakauru kotahi me te putanga rua.
^ Ka taea e te arai taratahi te huri i te whakawhiti tata me te whakauru whakapiri i roto i te waahi kino ki te tohu whakaputa transistor ka tuku ki te waahi haumaru. Ko te transistor putanga i waenganui i te ec kua rite rawa ki te whakakā kowhiringa o "waahanga hurihuri/waahanga noa" , i tua atu, he tohu whakaurunga poto iahiko, he tohu whakaoho ara iahiko tuwhera ranei, ka whakaratohia e te ara iahiko mo te tuku hiko hiko.
^ Kei te hiahia tenei hua ki te tuku hiko 20-35VDC o waho.
^ Ko te tohu tohu tohu kua tohua ki te rama whero me te kowhai hei tohu i te mana mahi o te rei whakaputa, ina he mo te ohorere ka whero te rama, i te wa e mahi ana he kowhai te rama.
* Tuku hiko pahi, tirohia te taapiri mo nga taipitopito.
