Hifi-level 2.0 stereo Bluetooth digital power amplifier board TPA3116 50WX2 ukukhulisa umsindo wesipikha ngesihlungi

Ithiphu: Kuphela uma okokufaka komsindo kwanele futhi i-voltage yokunikezela/yamanje yanele lapho kungaba khona amandla anele okukhiphayo. I-voltage yokunikezwa kwamandla iphezulu, amandla ahlobene azoba mkhulu, futhi uphondo olunokuphazamiseka okuhlukile luzoba namandla ahlukene okukhipha. Endabeni ye-voltage eyanele kanye neyamanje, inani elikhulu le-horn ohm likhulu, amandla omsindo ahlobene abe mancane, sicela unake!

Amandla kagesi kagesi: 12V ------ 8 ohm isipikha /12W(isiteshi esingakwesokunxele) + 12W(isiteshi esingakwesokudla), isipikha esingu-4 Ohm /20W+ 20W
15V ----- 8 EUR /18 + 18W, 4 EUR/ngaphezu kuka-30 + 30W
19V ------8 EUR /32 + 32W, 4 EUR/ngaphezu kuka-45 + 45W
24V ------8 EUR /38 + 38W, 4 EUR/ngaphezu kuka-55 + 55W
Okokufaka komsindo kwe-AUX + I-Bluetooth 2-in-1 ileveli ye-HIFI enesihlungi esingu-50Wx2 ibhodi le-Bluetooth digital amplifier yamandla

Ukuhlunga ibhendi
Qaphela! Isinki sokushisa esineglue engu-3M sidinga ukunamathiselwa ku-chip ngokwayo, bheka esithombeni esichazayo, lapho kushisa khona kunamathela kakhulu futhi kube ngcono ukuhamba kwe-thermal. Inguqulo yecala idinga ukuhlanganisa ikesi ngokwalo, futhi inguqulo yekesi iza ne-screwdriver.
Lo mkhiqizo ugcwele izinto zokwakha, ukusebenza okuphezulu kakhulu, intengo ephezulu, ikakhulukazi umculo we-HIFI ukuze unikeze isikhulisi samandla sekhwalithi ephezulu.
I-TPA3116D2 iyisikhulisamandla samandla se-Class D eyethulwe inkampani ye-TI, enamapharamitha enkomba aphezulu kakhulu. Imvamisa yokushintshashintsha ingafinyelela ku-1.2MHZ, futhi ukuhlanekezela kokuphuma kwamandla aphezulu kungaphansi kuka-0.1%.
Nge-AUX ne-Bluetooth izindlela ezimbili zokufaka umthombo womsindo, ezimbili kokukodwa;
I-Potentiometer yokulungisa ivolumu, ngokushintsha, ukulawula ivolumu kalula, ilungele kakhulu izikhulumi ze-DIY.
Nge-inductance yesihlungi, umsindo uyindilinga futhi ucacile.
Isixhumi se-Copper DC, ukuphela kocingo, ukumelana nomthamo omkhulu wamanje, akukho ukushisa, akukho monakalo wezintambo, izintambo ezinhle, akulula ukujikeleza okufushane.
Intambo yekhanda le-DC ingahambisana nesixhumi esibonakalayo samandla okokufaka walo mkhiqizo, ngisho noma ungenayo i-adaptha yekhanda le-DC noma ibhethri, ingaxhumeka kalula.
Inguqulo ye-Bluetooth engu-5.0, ukusebenza kahle kokudlulisela okuphezulu, ibanga elide lokudlulisela.
Inothi elizosetshenziswa: Iswishi yamandla ebhodini iyiswishi yokulinda, futhi umshini usesimweni sokulinda samandla amancane ngemva kokucisha iswishi. Ukuze ucime ngokuphelele amandla noma uma engasetshenziswa isikhathi eside, ipulaki ye-DC emshinini inganqanyulwa.

Izimpendulo zemibuzo:

1. Ungakhetha kanjani ukunikezwa kwamandla?

Ukunikezwa kwamandla kwebhodi kubalulekile. Lapho i-voltage iphakeme, iba nkulu yamanje, namandla okukhiphayo anele, uma une-12V 1A kuphela, ungaletha izipikha eziyi-3-4 intshi. Uma u-19V 5A noma ngaphezulu, akukho nkinga ngamasentimitha angu-8-10, futhi ukunikezwa kwamandla kufanele kube yigugu kakhulu. Uma i-voltage iphansi kakhulu, ukukhuliswa komsindo kulula ukubangela ukuphazamiseka komsindo, uma i-current incane kakhulu ukukhuphula isikhulumi sizodonsa i-voltage phansi, umsebenzi ungavamile noma izinga lomsindo liphansi.

Kunconywe ukusebenzisa amandla kagesi we-18V19V24V, amanje angaphezu kwe-3A. Uma une-9V12V noma i-1A 2A kuphela yamandla, ingasetshenziswa futhi kodwa amandla mancane, naka ivolumu ephezulu uma usebenzisa kungase kuhlanekezele ikhwalithi yomsindo.

2. Indlela yokukhetha isikhulumi?

Izimpondo ezisetshenziswa ngokuvamile ziyi-8 ohms, azikwazi ukuhlukanisa phakathi kwe-polarity enhle nengalungile, umphumela uyafana, ama-ohms angu-4 ophondo nawo angasetshenziswa. Uma amandla akho ophondo amancane, angase abe phakathi kuka-10W-30W angasetshenziswa, i-voltage yokuhlinzeka incane ukuvimbela umsindo omkhulu ngemva kokushisa uphondo, njengokukhetha ukunikezwa kwamandla ngaphansi kwe-15V. Uma uphondo lwe-50W-200w, ungakhathazeki ngenkinga yokuvutha kophondo, ungakhetha ukunikezwa kwamandla ka-12-24V, ukuphakama kwe-voltage ekhethiwe, bese kuba mkhulu umsindo ophumayo noma amandla.

3. Ungakhetha kanjani imodi yokufaka yomsindo ye-Bluetooth noma ye-AUX?

Faka amandla ebhodini lesikhulisi samandla, xhuma isipika, vula inkinobho yomsindo isibani sesikhombi esiluhlaza okwesibhakabhaka, vula Izilungiselelo zefoni -- I-Bluetooth -- sesha okuthi "BT-WUZHI", bese uchofoza okuthi xhuma, ngemva kokuxhumeka ngempumelelo, kuzoba nokukhala. ithoni ye-dong, ngalesi sikhathi ngemodi ye-Bluetooth, ungadlala umculo, amandla alandelayo azoxhunywa ngokuzenzakalelayo ocingweni.

Uma ufuna ukusebenzisa okokufaka komsindo kwe-AUX, unganqamula uxhumano lwe-Bluetooth, kuzophinde kube nokwaziswa komsindo, xhuma ikhebula lomsindo ukuze udlale umculo. KUmodi ye-AUX (LINE IN), i-Bluetooth iguqulelwa ngokuzenzakalelayo kumodi ye-Bluetooth.

4. Umsindo omncane ulungile, ngemva kokuba umsindo uba phezulu, kunomsindo oguqubele?
Umsindo uhlanekezelwe, sicela ushintshe i-adaptha yamandla ngezinga eliphezulu likagesi.

5. Umsindo omncane ulungile, ngemva kokuba umsindo uba phezulu, kukhona okwenzekayo kokusalela komsindo?
Amandla okokufaka awanele, isiphakeli samandla ngokwaso sivala ukuvikela ngezikhathi ezithile, sicela ushintshe ukunikezwa kwamandla okunamandla; Noma amandla makhulu kakhulu, ibhodi le-amplifier lamandla liyashiswa ngokujulile, futhi ukuvikela okushisayo kubonakala, kunciphisa ukusetshenziswa kwamandla noma ukuqinisa ukuchithwa kokushisa.
