Yog, koj ua tau siv cov kev lom zem hauv tsev ib txwm siv lub tso suab nrog koj "tshiab" lub zog computer - muab sab hauv tsheb suab amplifier ! Ua ntej, nco ntsoov tias koj muaj 12v ntawm dc+ cov tswv yim ntawm amp tso thiab 12v rau cov chaw taws teeb input rau lub amp tso . Cov amp xav tsis tig rau yog hais tias lub chaw taws teeb hlau tsis txuas thiab powered.

Tsis tas li ntawd, nws siv pes tsawg amps los khiav lub tso suab tsheb?

Ib yam lub tso suab lub taub hau yuav xav tau txog 5 cov amps ntawm lub zog. Yog tias koj xav crank nce ntim rau ob tog thiab npaj siv lub tshuab hluav taws xob muaj zog, ces 5 cov amps tej zaum yuav tsis txaus ib yam nkaus. Peb ua muaj cov khoom siv fais fab uas muaj txog li 30 cov amps.

Tsis tas li ntawd, muaj pes tsawg amps ua 1000 watt amp kos? Watt = Volts * Amps yog li yog lub amp tso tawm 1000W RMS thiab siv 12V muab rau nws nws xav tau 83 Amps. Muaj ob yam tseem ceeb los xav txog. Lub amp tsis yog 100% npaum li xav 50 % ua tau zoo thiab koj muaj 166 amps. Tom qab ntawd vim tias 1000W yog qhov siab tshaj, txo qis rau 1/3 ntawm qhov uas muab rau koj txog 55 Amps.

Ntawm no, muaj pes tsawg amps puas lub tsheb amplifier kos?

Koj yuav tsum pib nrog koj lub zog muab (lub zog ntsuas hauv watts) yog li koj amp tso tso tawm 300w nrog dab tsi, 13.8v ntawm qhov muaj peev xwm hluav taws xob? Yog li koj amplifier , nrog koj lub cev them nyiaj zaum ntawm 13.8 volts, tso tawm 300w, thiab koj qhov tam sim no kos ntawm koj amplifier yog 21.74 amperes ( cov amps ).

Muaj pes tsawg volts uas tus neeg hais lus siv?

Txij li thaum lub tshuab hluav taws xob nyob ntawm qhov chaw zoo ib yam li hais lus , cov hais lus yuav tsum tau tsuas yog ib tug kab theem suab teeb liab raws li ib tug input. Cov kab cim kab cim feem ntau nyob ib puag ncig 1-2 qhov hluav taws xob , thiab tuaj yeem sib kis tau ntau me me cable (feem ntau 20-26 AWG).
