Māhele māhele mana(PDUs) he ʻāpana koʻikoʻi o nā kikowaena ʻikepili hou, nā lumi kikowaena a me nā keʻena pūnaewele, e hāʻawi ana i kahi ala hilinaʻi a maʻalahi hoʻi e puʻunaue i ka mana mai kahi kumu hoʻokahi i nā polokalamu he nui. Hele mai nā PDU i nā ʻano like ʻole, ka nui a me nā hiʻohiʻona, akā ʻo kekahi o nā mea koʻikoʻi e noʻonoʻo ai i ke koho ʻana i kahi PDU ʻo ia kāna palapala palekana. Ma ʻAmelika ʻĀkau, ʻelua mau kūlana palekana PDU nui āu e ʻike ai: UL a me CSA.
Hōʻike manaʻo UL PDU:
Kū ʻo UL no Underwriters Laboratories, kahi hui kūʻokoʻa i ʻike ʻia i ka honua e hoʻāʻo a hōʻoia i nā huahana no ka palekana a me ka hana. Hoʻopili ka papahana hōʻoia PDU o UL i nā ʻano like ʻole o nā ʻano PDU a me nā noi, me nā PDU rack-mount, nā PDU papa-mauna, nā PDU pā-mauna, a me nā PDU mālama ea. ʻO ka palapala hōʻoia PDU o UL e pili ana i ka hoʻāʻo ʻana i ka palekana uila, ka pale ahi, nā kūlana kaiapuni, a me nā wahi ʻē aʻe e pili ana. No ka loaʻa ʻana o ka palapala hōʻoia UL, pono nā PDU e hoʻāʻo a hoʻokō i nā kūlana koʻikoʻi, me UL 60950-1 a me UL 60950-22. Hōʻike maʻamau ka hōʻoia UL no nā PDU he palekana a hilinaʻi hoʻi no ka hoʻohana maʻamau.
UL PDU pono:
ʻO kekahi o nā mea maikaʻi o nā PDU i hoʻopaʻa ʻia e UL, ʻo ia ka pale ʻana i nā pōʻino uila e like me ka overloads, nā pōkole pōkole, a me nā hemahema o ka honua. UL Listed PDUs also follows best practices in design, materials, and manufacturing to minimize the risk of defects, malfunctions, or malfunctions that could result in the power outages, equipment damage, or the user injury. Lawe pū ʻia nā PDU UL Listed i kahi inoa inoa hilinaʻi e hoʻonui ai i ka hilinaʻi a me ka hauʻoli o ka mea kūʻai aku.
Hōʻike manaʻo CSA PDU:
ʻO ka inoa piha o CSA ʻo ia ʻo Canadian Standards Association, kahi hoʻonohonoho maʻamau a me ka hui hōʻoia e lawelawe ana ma Kanada a me nā mākeke honua ʻē aʻe. Hoʻopili ka papahana hōʻoia PDU o CSA i nā ʻano PDU like a me nā noi i ka UL, akā aia kekahi mau ʻokoʻa i nā kūlana a me nā kaʻina hana hoʻāʻo. Aia ka CSA's PDU palapala hōʻoia i nā hoʻokolohua e pili ana i ka palekana uila, electromagnetic compatibility, a me nā koi kaiapuni. No ka hōʻoia ʻia ʻana o ka CSA, pono ka PDU e hoʻokō i nā kūlana kūpono a me nā hoʻoponopono āpau a hoʻopaʻa ʻia i nā nānā manawa a me nā hoʻokolohua maikaʻi.
Nā Pōmaikaʻi CSA PDU:
ʻO kekahi o nā mea maikaʻi o nā PDU i hōʻoia ʻia e CSA, ʻo ia ka mālama ʻana i nā kūlana Kanada a me ka honua, e hōʻoiaʻiʻo ana i ka hoʻohālikelike a me ka launa pū ʻana me nā lako a me nā ʻōnaehana ʻē aʻe. Hoʻāʻo kūʻokoʻa ʻia nā PDU i hōʻoia ʻia e CSA, e hōʻemi ana i ka manawa o nā pilikia hana a i ʻole ka hoʻokō ʻole ʻana i nā lula. Hele mai nā PDU i hōʻoia ʻia e CSA me nā koho a me nā koho kākoʻo no ka maluhia o ka noʻonoʻo a me ka pale ʻana i nā hemahema a i ʻole nā hemahema.
Nā PDU UL a me CSA:
ʻOiai kaʻana like nā UL a me CSA PDU i kā lākou papahana hōʻoia, aia kekahi mau ʻokoʻa e pili ana i kāu koho PDU. No ka laʻana, loaʻa paha i kahi UL PDU nā koi hoʻāʻo kiʻekiʻe a me nā koina loiloi koʻikoʻi, ʻoiai ʻo CSA PDU ke kau nui aku i ka hana o ke kaiapuni a me nā hoʻoiho electromagnetic. Ma muli o kāu mau pono a me kou makemake, hiki iā ʻoe ke koho iā UL a i ʻole CSA i hōʻoia ʻia i nā PDU a i ʻole nā mea ʻelua e hoʻokō i kāu mau koi hoʻoili mana.
i ka hopena:
He mea koʻikoʻi nā kūlana PDU no ka hōʻoia ʻana i ka hāʻawi ʻana i ka mana palekana a hilinaʻi i nā kaiapuni IT o kēia lā. ʻO UL a me CSA nā kūlana PDU nui ʻelua ma ʻAmelika ʻAmelika, e uhi ana i nā ʻano āpau o ka palekana a me ka hana PDU. ʻO ke koho ʻana i kahi PDU UL- a i ʻole CSA-listed PDU e hāʻawi i nā pono he nui, e like me ka pale ʻana i nā pōʻino uila, ka hoʻokō ʻana i nā kūlana a me nā lula, a me nā koho a me ke kākoʻo. E hoʻomanaʻo e nānā i nā palapala hōʻoia a me nā helu o nā PDU ma mua o ke kūʻai ʻana a i ʻole ke kau ʻana iā lākou e pale i nā pilikia.
