UL Safety Testing Institute ndiyo yovomerezeka kwambiri ku United States, ikuchitanso ntchito zoyesa chitetezo ndikuzindikiritsa mabungwe akuluakulu aboma! Pambuyo pa chitukuko cha zaka zana, UL yakhala bungwe lodziwika bwino la ziphaso padziko lonse lapansi lomwe lili ndi dongosolo lake lokhazikika la kayendetsedwe ka bungwe, kakulidwe ka miyezo ndi njira zopangira ziphaso. Pakalipano, UL ili ndi ma laboratories asanu ku United States mainland, omwe ali ku Northbrook Town, kumpoto kwa Chicago, USA, ndipo panthawi imodzimodziyo ku Taiwan ndi Hong Kong akukhazikitsa labotale yofananira.
Mu 2017, kwa nthawi yoyamba kuti UL US likulu labotale zabwino Zenithsun zabwino katundu magetsi Yang bokosi magawo luso ndi mphamvu ya kuzindikira kampani ya Zenithsun zabwino ndi kudziwa kupanga 2 ya 20A @ 120Vac240Vac wapawiri-voltage resistive load box kaye kuyesa!
Mu 2020, akulimbikitsidwa ndi UL New York Laboratory, Zenithsun adapezanso labotale ina ya UL yolumikizirana ndi bokosi la resistive load resistor, ndipo adalandira ma seti 8 amtundu wapawiri voltage resistive dummy load box 7.4kW @ 120Vac240Vac kuti agwirizane bwino. Nthawi yomweyo zomwe zidafika ku United States patatha mwezi umodzi wogwiritsa ntchito, tidalandira kampani ya UL yogwiritsa ntchito dipatimentiyi kuti tizindikire bwino bokosi la Zenithsun load resistance!
Kumasulira: Timakonda mabokosi onyamula awa mpaka pano. Amisiri anga onse amakonda mabokosi olemetsawa chifukwa ndi osavuta kuwongolera komanso ndi ochepa kukula kwake, choyipa chokha ndichakuti mafani ndiphokoso pang'ono, koma tikudziwa kuti ndizabwinobwino)
Zikomo makasitomala padziko lonse thandizo ndi kuzindikira Zenithsun kampani, tipitiriza kuyesetsa kulimbikitsa luso luso kuwongola, kuyesetsa kulenga zinthu ndi ntchito resistor kwambiri ndi ntchito makasitomala athu!
