Ingabe Uyazi Yini I-PDU?

I-PDU (iyunithi yokusabalalisa amandla) yakhelwe ukuhlinzeka ngokusabalalisa amandla kumadivayisi kagesi afakwe kwikhabethe. Inochungechunge oluhlukahlukene lokucaciswa okunemisebenzi ehlukene, izindlela zokufaka, nezinhlanganisela zamasokhethi, okuhlinzeka ngesixazululo samandla afakwe ngama-rack afanelekile ezindaweni ezahlukene zamandla. Ukusetshenziswa kwama-PDU kwenza ukusatshalaliswa kwamandla ekhabetheni kuhlanzeke, kuthembeke, kuvikeleke, kubuchwepheshe, futhi kube kuhle, futhi kwenza ukugcinwa kwezinto zikagesi ekhabetheni kube lula futhi kuthembekile.

Izinzuzo zesokhethi ye-PDU zimi kanje: ukuhlelwa kokuklama okunengqondo, ikhwalithi eqinile nezinga eliphezulu, isikhathi eside sokusebenza esiphephile nesingenazinkathazo, ukuvikelwa okungcono kwezinhlobo ezihlukahlukene zokuvuza kanye ne-overcurrent kanye nokulayisha ngokweqile, ipulaki elivamile kanye nokususa isenzo futhi akulula. ukulimaza, ukukhuphuka okuncane kokushisa, ukufakwa okuguquguqukayo nokulula, okulungele amakhasimende embonini anezidingo eziqinile kugesi. Iphinde futhi ivimbele ukuphelelwa amandla njalo, ukuvutha, umlilo nezinye izingozi zokuphepha ezibangelwa ukuthintana kabi kanye nomthwalo omncane wokuphakelwa kukagesi okuvamile.

Ingafakwa ekhabetheni elingu-19-intshi noma i-rack futhi ithatha isikhala esingu-1U kuphela. Ingafakwa ngokuvundlile (okujwayelekile ngamayintshi angu-19) noma mpo (ngokuhambisana nokuthunyelwe kwekhabhinethi). Ukuvikelwa okuningi: Idivayisi eyakhelwe ngaphakathi yesiteji sokuvikela ukuhlinza ukuze inikeze isivikelo esinamandla, kuyilapho ihlinzeka ngokuhlunga, i-alamu, ukuqapha amandla nokunye ukuxhumana kwangaphakathi kwedivayisi yokubuka: i-jack spring iyi-phosphobronze, ukunwebeka okuhle, ukuthintana okuhle kakhulu, ingamelana nezikhathi ezingaphezu kuka-10,000 zokufakwa kanye ukususwa; Wonke amamojula esokhethi axhunywe nge-spotwelding ngamabha ethusi.

Izinketho ezihlakaniphe kakhulu, ukuphatha okulula nokulawula kude: umkhiqizo ungakhetha isibonisi sedijithali esengeziwe, i-alamu engajwayelekile, ukuphathwa kwenethiwekhi neminye imisebenzi, egqamisa ubuhlakani bomkhiqizo, uthuthukise ukusebenziseka kwawo nokuphatha kalula.

Umbani wokuvikela amasekethe amaningi:

• ukuvikelwa kokuhlinzwa: ukumelana nokushaqeka okukhulu
• yamanje: 20KA noma ngaphezulu;
• Umkhawulo we-voltage: ≤500V noma ngaphansi;
• Ukuvikelwa kwe-alamu: Isibonisi samanje sedijithali ye-LED kanye nakho konke ukuqapha kwamanje kanye ;
• isivikelo sokuhlunga: Ngokuvikela okuhle kwesihlungi, okukhipha amandla ahlanzekile ahlanzekile kakhulu;
• Ukuvikelwa kokulayishwa ngokweqile: kunikeza ukuvikeleka kokugcwala kakhulu kuzo zombili izigxobo, okungavimbela ngempumelelo izinkinga ezibangelwa ukugcwala ngokweqile.
