Amayunithi Okusabalalisa Amandla (ama-PDU) ngokuvamile anezimbobo ezihlukahlukene zezengezo noma izici kuye ngomklamo wazo nokusetshenziswa okuhlosiwe. Ngenkathi izici ezithile zingahluka phakathi kwamamodeli ahlukene we-PDU nabakhiqizi, nazi ezinye izimbobo ezengezo ezijwayelekile ongazithola kuma-PDU:
* Izitolo zikagesi: Ama-PDU ngokuvamile ahlanganisa izindawo eziningi zokuphuma kwamandla kagesi noma izitsha lapho ungaxhuma khona izisetshenziswa zakho noma okokusebenza. Inombolo nohlobo lwezitolo zingahluka, njenge-NEMA 5-15, NEMA 5-20, IEC C13, IEC C19, njll., kuye ngendawo eqondiwe ye-PDU kanye nokusetshenziswa okuhlosiwe.
* Izimbobo zenethiwekhi: Ama-PDU amaningi esimanje anikezela ngoxhumano lwenethiwekhi ukuze anike amandla ukuqapha okukude, ukulawula, nokuphathwa kokusetshenziswa kwamandla. Lawa ma-PDU angase afake izimbobo ze-Ethernet (CAT6) noma amaphrothokholi enethiwekhi asekelayo njenge-SNMP (I-Simple Network Management Protocol) ukuze ahlanganiswe nezinhlelo zokuphatha ezimaphakathi.
* Izimbobo ze-serial: Izimbobo ze-serial, njenge-RS-232 noma i-RS-485, ngezinye izikhathi ziyatholakala kuma-PDU. Lezi zimbobo zingasetshenziselwa ukuxhumana kwasendaweni noma okukude ne-PDU, okuvumela ukucushwa, ukuqapha, nokulawula ngokusebenzisa isixhumi esibonakalayo se-serial.
* Izimbobo ze-USB: Amanye ama-PDU angase abe nezimbobo ze-USB ezingasetshenziselwa izinjongo ezihlukahlukene. Isibonelo, zingavumela ukuphathwa kwendawo kanye nokucushwa, izibuyekezo ze-firmware, noma nokushaja amadivayisi anamandla e-USB.

* Izimbobo zokuqapha imvelo: Ama-PDU adizayinelwe izikhungo zedatha noma izindawo ezibucayi angase afake izimbobo zezinzwa zemvelo. Lezi zimbobo zingasetshenziselwa ukuxhuma izinzwa zokushisa, izinzwa zomswakama, noma amanye amadivayisi okuqapha imvelo ukuze kuqashwe izimo esikhungweni sedatha noma indawo.
* Izimbobo zenzwa: Ama-PDU angase abe nezimbobo ezinikelwe zokuxhuma izinzwa zangaphandle eziqapha ukusetshenziswa kwamandla, ukudonsa kwamanje, amaleveli kagesi, noma amanye amapharamitha kagesi. Lezi zinzwa zingahlinzeka ngedatha eyimbudumbudu eyengeziwe mayelana nokusetshenziswa kwamandla futhi zisize ukuthuthukisa ukusebenza kahle kwamandla.
* Amachweba we-Modbus: Amanye ama-PDU ebanga lezimboni angase anikeze amachweba we-Modbus ukuze axhumane nezinhlelo zokulawula zezimboni. I-Modbus iyiphrothokholi yokuxhumana esetshenziswa kabanzi ku-automation yezimboni futhi ingenza kube lula ukuhlanganiswa nezinhlelo ezikhona zokulawula.
* Imbobo ye-HDMI: Nakuba izimbobo ze-HDMI (High-Definition Multimedia Interface) ngokuvamile zingatholakali kuma-PDU, ezinye izisetshenziswa ezikhethekile zokuphatha amandla noma izisombululo ezifakwe kuma-rack zingase zihlanganise kokubili ukusatshalaliswa kwamandla nokusebenza kwe-AV, njengamarack alalelwayo nokubukwayo emakamelweni enkomfa noma izindawo zokukhiqiza imidiya. Ezimweni ezinjalo, idivayisi ingase ibe yisixazululo esiyingxubevange esihlanganisa izici ze-PDU kanye noxhumo lwe-AV, okuhlanganisa nezimbobo ze-HDMI.
Kubalulekile ukuqaphela ukuthi akuwona wonke ama-PDU azoba nawo wonke lawa machweba angeziwe. Ukutholakala kwalezi zici kuzoncika kumodeli ethile ye-PDU kanye nokusetshenziswa kwayo okuhlosiwe. Lapho ukhetha i-PDU, kubalulekile ukuthi ucabangele izidingo zakho bese ukhetha enikeza izimbobo ezidingekayo nokusebenza kwezidingo zakho ezithile.
Manje woza ku-Newsunn ukuze wenze ngezifiso ama-PDU akho!
