Isingeniso
I-ITECH IT6720 ingumthombo wamandla we-DC olawula idijithali osebenza kakhulu oklanyelwe uhla olubanzi lwezinhlelo zokusebenza, kusukela ocwaningweni lwaselabhorethri kuya ekuhlolweni komugqa wokukhiqiza. Ihlinzeka ngomthamo ozinzile futhi onembayotagu-e kanye nokuphumayo kwamanje okunomshini ongaguquki ozenzakalelayo (CC) kanye nevolumu engaguqukitage (CV) izindlela zokuguqula. Ifakwe imisebenzi eminingi yokuvikela, lokhu kunikezwa kwamandla kuqinisekisa ukusebenza okuphephile nokuthembekile.

Umfanekiso 3: Okuningiliziwe view wephaneli yangemuva, ekhombisa iswishi yamandla, okokufaka kwamandla e-AC, isixhumi samaphini angu-9 (okusetshenziswa kwafekthri kuphela), kanye nefeni yokupholisa.
Setha
- Ukuxhuma kwamandla: Xhuma intambo yamandla enikeziwe kokokufaka kwamandla e-AC kuphaneli engemuva (Umfanekiso 3). Qinisekisa ukuthi iswishi yamandla isendaweni VALIWE ngaphambi kokuxhuma.
- Voltage Ukukhetha: Qinisekisa ivolumutagIswishi yesikhethi kuphaneli engemuva isethelwe kuvolumu ye-AC yendawo efaneletage (110V noma 220V). Lungisa uma kunesidingo usebenzisa i-screwdriver encane enekhanda eliyisicaba.
- Uxhumano Lokukhiphayo: Xhuma umthwalo wakho kumatheminali okukhiphayo kuphaneli yangaphambili. Itheminali ebomvu ithi positive (+), itheminali emnyama inegethivu (-), kanti itheminali eluhlaza iphansi. Qinisekisa ukuxhumana okuvikelekile.
- Amandla Okuqala Avuliwe: Phenya iswishi yamandla kuphaneli engemuva uye endaweni ethi ON. Isibonisi sephaneli yangaphambili kufanele sikhanyise.

Imiyalelo yokusebenza
- Ukusetha Voltage Namanje: Sebenzisa inkinobho enkulu ejikelezayo ukulungisa ivolumutage namanani amanje. Cindezela inkinobho ethi 'Shift' ukuze uguqule phakathi kwezindlela zokulungisa ezimahhadla nezicolekileyo ukuze uthole ukulawula okunembile. Isibonisi sizobonisa amanani asethiwe.
- Okukhiphayo KUVULIWE/KUVALIWE: Cindezela inkinobho ethi 'Vula/vala' ukuze unike amandla noma ukhubaze okukhiphayo. Isibonisi sizobonisa uma okukhiphayo kusebenza.
- Ukuguqulwa okuzenzakalelayo kwe-CC/CV: Ukunikezwa kwamandla kuzishintsha ngokuzenzakalela phakathi kwe-Constant Voltage (CV) kanye namamodi e-Constant Current (CC) kuye ngomthwalo. Inkomba ehambisanayo (CC noma i-CV) kusibonisi izokhanya.
- Imisebenzi Yokuvikela: Iyunithi ifakwe i-Over Current Protection (OCP), Over VoltagI-e Protection (OVP), kanye Nokuvikelwa Kwamazinga Okushisa Okungaphezulu (OTP). Uma noma iyiphi yalezi zimo ihlangatshezwana nayo, okukhiphayo kuzocisha futhi inkomba efanele izokhanya.
- Imisebenzi Yenkumbulo: Sebenzisa izinkinobho 'Londoloza' kanye ne-'Prog' (A, B, C, D) ukuze ugcine futhi ukhumbule ivolumu esetshenziswa njalotage kanye nezilungiselelo zamanje. Bheka imanuwali enemininingwane ngezinyathelo ezithile zokuhlela.
- Ukukhiya Kwekhibhodi: Inkinobho 'Khiya' ingasetshenziswa ukuvimbela izinguquko zephutha kuzilungiselelo phakathi nokusebenza.

Isondlo
Ukushintshwa kwe-Fuse
Amandla kagesi e-ITECH IT6720 afakwe i-fuse eshintshwayo ukuze avikeleke kuma-overcurrent. Uma iyunithi yehluleka ukuvula amandla noma ivaleka ngokungalindelekile, i-fuse ingase idinge ukushintshwa. Isibambi se-fuse sitholakala kuphaneli engemuva, eduze nokokufaka kwamandla e-AC.
- Nqamula Amandla: Qinisekisa ukuthi ugesi unqanyulwe ngokuphelele kumapayipi amakhulu e-AC ngaphambi kokuzama noma yikuphi ukulungisa.
- Thola umnikazi we-Fuse: Khomba umbambi wefuse kuphaneli engemuva (bheka uMdwebo 3). Ngokuvamile ikepisi elincane, eliyisilinda elingasonteka noma likhishwe.
- Susa i-Old Fuse: Sebenzisa i-screwdriver encane enekhanda eliyisicaba noma uzipho lwakho ukuze uvule kahle noma usonte isibambi se-fuse. Susa ngokucophelela i-fuse endala.
- Hlola Isilinganiso se-Fuse: Isilinganiso se-fuse esidingekayo siphrintwa kuphaneli engemuva eduze kwesibambi se-fuse. Ngokusebenza kwe-110V AC, i-fuse ivamise ukuba ngu-3.15A/250V. Ngokusebenza kwe-220V AC, ingu-1.5A/250V. Njalo shintsha ufake i-fuse yohlobo olufanayo ncamashi nesilinganiso.
- Faka I-Fuse Entsha: Faka i-fuse entsha kusibambi se-fuse bese uyibuyisela endaweni yamandla, uqinisekisa ukuthi ihlezi ngokuvikelekile.
- Xhuma kabusha Amandla: Phinda uxhume ugesi kumapayipi amakhulu e-AC futhi uhlole ukusebenza kwawo.
Qaphela: Uma i-fuse ishaya ngokuphindaphindiwe, kungase kube nenkinga eyisisekelo ngeyunithi noma ukusetha kwakho ugesi. Xhumana nosekelo lwezobuchwepheshe ukuze uthole usizo.

Ukuxazulula inkinga
- Iyunithi ayivuli:
1. Hlola ukuthi ingabe intambo yamandla ixhumeke ngokuvikelekile kukho kokubili iyunithi kanye ne-AC outlet.
2. Qinisekisa ukuthi iswishi yamandla kuphaneli yangemuva isesimweni IVULIWE.
3. Hlola i-fuse kuphaneli elingemuva. Uma ishaywe umoya, yishintshe ufake i-fuse yesilinganiso esifanele (bheka isigaba Sokulungisa). - Akukho okukhishwayo voltage / yamanje:
1. Qinisekisa ukuthi inkinobho yokuvula/VULA ephaneli yangaphambili ivuliwe.
2. Hlola ukuthi noma yiziphi izinkomba zokuvikela (OCP, OVP, OTP) ezikhanyisiwe. Uma kunjalo, xazulula ukugcwala/ukweqisatage/isimo sokushisa ngokweqile bese usetha kabusha iyunithi.
3. Qinisekisa ukuthi umqulutage kanye nezilungiselelo zamanje azisethwanga ku-zero. - Ubunzima bokusebenzisa isikhombimsebenzisi/izindlela:
I-IT6720 isebenzisa inkinobho yokulawula eyodwa enamamodi amaningi. Bheka imanuwali yomsebenzisi enemininingwane (isixhumanisi se-PDF esinikezwe kumadokhumenti womkhiqizo) ukuze uthole incazelo ebanzi yemodi ngayinye (Imodi A, B, C, D) kanye nendlela yokuyizulazula usebenzisa izinkinobho zika-'Shift' kanye 'Nethi'Setha'. Zijwayeze ukulungisa amanani ngezindlela ezihlukene ukuze ujwayelane nesixhumi esibonakalayo.
Iwaranti kanye Nokusekela
I-ITECH ihlinzeka ngokusekela kochwepheshe kwemikhiqizo yayo ngaphambi nangemva kokuthengisa. Nganoma yimiphi imibuzo yobuchwepheshe, usizo lokusebenza, noma izimangalo zewaranti, sicela uthinte isevisi yamakhasimende ye-ITECH ngokuqondile.
Bheka i-ITECH esemthethweni webisayithi noma imibhalo efakwe nomkhiqizo wakho ukuze uthole imininingwane yokuxhumana yakamuva kanye nemininingwane yewaranti.
