Ubwino wa CSA PDU:
Ubwino umodzi wa CSA-certified PDUs ndikuti amatsatira miyezo yaku Canada ndi mayiko ena, kuwonetsetsa kuti zikugwirizana ndi kugwirizana ndi zida ndi machitidwe ena.Ma PDU ovomerezeka ndi CSA amayesedwanso paokha ndikutsimikiziridwa, kuchepetsa mwayi wazovuta zantchito kapena kusatsata malamulo.Ma PDU ovomerezeka ndi CSA amabweranso ndi chitsimikizo ndi njira zothandizira kuti mukhale ndi mtendere wamumtima komanso chitetezo ku zovuta kapena zolephera.
UL ndi CSA PDUs:
Ngakhale ma UL ndi CSA PDU amagawana zofanana zambiri pamapulogalamu awo aziphaso, palinso zosiyana zomwe zingakhudze kusankha kwanu kwa PDU.Mwachitsanzo, UL PDU ikhoza kukhala ndi zofunikira zoyezetsa kwambiri komanso njira zowunikira kwambiri, pomwe CSA PDU imatha kutsindika kwambiri momwe chilengedwe chimagwirira ntchito komanso kutulutsa mpweya wamagetsi.Kutengera zosowa zanu ndi zomwe mumakonda, mutha kusankha ma PDU ovomerezeka a UL kapena CSA kapena onse kuti akwaniritse zofunikira zanu zogawa mphamvu.
