Muaj pes tsawg watts tau 16 gauge hais lus hlau kov?
Txheem
Nyob rau hauv lub kaw lus nrov, nws yog ib qho tseem ceeb heev kom paub qhov tseeb gauge hlau uas koj yuav tsum tau siv nyob rau hauv thiaj li yuav ua kom nws ua hauj lwm kom zoo thiab ua tau raws li cov hluav taws xob tam sim no ntawm lub system. Kev siv lub ntsuas hluav taws xob tsis raug cai yuav muab lub zog tsis txaus thiab ua rau muaj hluav taws kub thiab nyab xeeb.
Hauv phau ntawv qhia no, kuv yuav taug kev koj los ntawm ntau npaum li cas watts 16 gauge tus neeg hais lus xov tooj tuaj yeem ua tau, thiab koj yuav tsum paub dab tsi txog cov hom xov hlau no hais txog lawv cov yam ntxwv thiab muaj peev xwm.
Tus naj npawb ntawm watts uas 16 gauge hais lus xaim tuaj yeem ua tau
Lub 16 gauge tsheb audio speaker hlau yog ntsuas rau 75-100 watts. Nws yog feem ntau siv rau kev khiav tsheb ntev dua thiab cov neeg hais xov tooj cua hauv tsev, lossis luv dua mus txog 20 feet. Tsis tas li ntawd, nws tuaj yeem ua haujlwm tsawg dua 225 watts, xws li nruab nrab lub zog subwoofer nrog luv luv. Yog li ntawd, 16 gauge hlau yog qhov kev xaiv zoo tshaj plaws rau kev muaj peev xwm ntau dua lossis ntev dua.
Xaiv qhov raug xaim ntsuas
Cov peb yam no txiav txim siab qhov tseeb hais lus hlau loj:
- Lub zog tso zis ntawm koj lub tso suab tso suab lossis lub suab nrov.
- Nominal impedance los yog hais lus impedance.
- Ntev ntawm cable yuav tsum tau nruab rau cov neeg hais lus.
Rau 16 gauge tsheb lub suab hais lus hlau, qhov siab tshaj plaws pom zoo hais lus hlau ntev raws li tus neeg hais lus impedance (ohms load) yog raws li hauv qab no: (1)
| Hlau hom 16 gauge | Dynamic 2 Ohm | Dynamic 4 Ohm | Dynamic 6 Ohm | Dynamic 8 Ohm | Dynamic 16 Ohm |
| Hais lus tooj liab | 12 ko taw (3.6 m) | 23 ko taw (7.2 m) | 35 ko taw (10.7 m) | 47 ko taw (14.3 m) | 94 ko taw (28.7 m) |
| Copper Clad Aluminium Hlau (CCA) | 9 ko taw (2.6 m) | 17 ko taw (5.2 m) | 26 ko taw (7.8 m) | 34 ko taw (10.5 m) | 69 ko taw (20.9 m) |
Cov lus nug nquag nug
Dab tsi yog daim ntawv thov rau 16 gauge speaker wires?
Feem ntau hais lus, koj tuaj yeem pom 16 lub ntsuas hluav taws xob hauv cov hlua txuas ntxiv, thiab nws yog siv rau txhua lub sijhawm uas siv cov hlua txuas ntxiv, suav nrog kev sib txuas cov khoom siv nyob ib ncig ntawm lub tsev, siv lub tshuab tshuab, thiab txiav cov hedges. Lub tsheb muaj peev xwm qee zaum muaj qhov tseem ceeb ntawm cov xov hlau nyob hauv lawv lub teeb taub hau, tig teeb liab, pib lub cev muaj zog, teeb nres tsheb, ignition coil, thiab alternators.
Muaj pes tsawg amps tuaj yeem 16 ntsuas hlau kov?
16 gauge speaker wire tuaj yeem ua 13 amps. Tsis tas li, raws li National Electrical Code (NEC), 16 gauge hlau tuaj yeem nqa 18 amps ntawm 90 degrees Celsius.
Puas yog txhua daim ntawv thov rau 16 ntsuas tooj liab hlau txwv rau 13 amps?
16 gauge hlau tuaj yeem kos 18 amps ntawm 90 degrees Celsius raws li NEC. Txawm li cas los xij, hauv cov kab txuas txuas ntxiv, nws feem ntau yog siv nrog qis dua. Cov ntawv thov tsheb sib txawv kiag li vim lawv tuaj yeem nqa tam sim no ntau dua li qhov xav tau lossis qhov tau teev tseg hauv NEC, piv txwv li: (2)
- 3 feet yog 50 amps
- 5 feet yog 30 amps
- 10 taw yog 18 txog 30 amps
- 20 ko taw yog 8 mus rau 12 amps
- 25 ko taw yog 8 mus rau 10 amps
Nws puas tuaj yeem khi 16 gauge hlau rau 18 gauge lossis 14 gauge hlau?
Raws li txoj cai, hlau yuav tsum muaj tsawg kawg yog 14 gauge rau AC siv. Yog li ntawd, txuas 16 gauge xaim mus rau 14 gauge hlau los ntawm lub Circuit Court breaker yog qhov txaus ntshai heev. Txawm li cas los xij, 14 gauge, 16 gauge thiab 18 gauge wires raug tso cai los sib xyaw hauv cov ntawv thov suab xws li hauv tsheb.. Tsuas yog xyuas kom lawv tau insulated kom zoo. Cov kev siv ntau tshaj plaws rau 18 ntsuas, zoo li 16 ntsuas, yog nyob rau hauv kev lag luam automotive thiab stereo, qhov chaw lawv ib txwm siv los ntawm DC (direct tam sim no) roj teeb.
Ua tib zoo saib qee qhov ntawm peb cov lus hauv qab no.
- Ntev npaum li cas yog 18 gauge hlau
- Cov hlau twg yog los ntawm lub roj teeb mus rau qhov pib
- Qhov luaj li cas hais lus hlau rau lub subwoofer
