UL Safety Testing Institute ndiyo ine chiremera zvakanyanya muUnited States, iri kuitawo munyika yekuongorora kuchengetedza uye kuzivikanwa kwemasangano makuru ehurumende! Mushure memakore anoda kusvika zana ebudiriro, UL yave sangano rine mukurumbira pasi rose retifiketi rine seti yaro yakasimba yehurongwa hwehurongwa hwehurongwa, kusimudzira zviyero uye maitiro ekupa zvitupa. Parizvino, UL ine marabhoritari mashanu muUnited States mainland, ine dzimbahwe kuNorthbrook Town, kuchamhembe kweChicago, USA, uye panguva imwe chete muTaiwan neHong Kong dzakateerana dzakagadzira rabhoritari inoenderana.
Muna 2017, kekutanga kuwana UL US dzimbahwe rabhoritari yeyakanaka Zenithsun yakanaka mutoro wemagetsi Yang bhokisi tekinoroji paramita uye kusimba kwekambani kucherechedzwa kweiyo yakanaka Zenithsun uye kuona kugadzirwa kwe2 seti ye20A @ 120Vac240Vac dual-voltage resistive. load box kutanga kuedza!
Muna 2020, yakakurudzirwa neUL New York Laboratory, Zenithsun yakawanazve imwe UL rabhoritari yeresitorendi mutoro bhokisi nhaurirano, uye yakawana 8 seti yehuviri voltage resistive dummy load box 7.4kW @ 120Vac240Vac odha yekubatana kwakanaka. Panguva imwecheteyo muchigadzirwa chakasvika kuUnited States mushure memwedzi mumwe wekushandiswa, takagamuchira iyo UL kambani ichishandisa dhipatimendi rekuzivikanwa kwakanaka kweZenithsun load resistance box!
Dudziro: Tinoda aya mabhokisi ekutakura kusvika zvino. Vese matekinoroji angu vanoda aya mabhokisi emutoro nekuti ari nyore kufambisa uye ari madiki muhukuru, chinongodzikira ndechekuti mafeni ane ruzha, asi isu tinoziva kuti zvakajairika)
Tinokutendai nevatengi pasi rese nerutsigiro uye kuzivikanwa kwekambani yeZenithsun, isu ticharamba tichishanda nesimba kusimbisa iyo tekinoroji simba rekusimudzira, kuyedza kugadzira akawanda uye zvirinani resistor zvigadzirwa uye masevhisi kune vatengi vedu!
