Hauv qhov no, cov lus teb yog yog. Ib yam li fluorescent ballasts cim 120 v - 277v ib , LED tsav tsheb cim 120 v - 277v ua tus kheej-kho rau qhov voltage ntawm lub hwj huam mov yog muab, piv txwv li qhov voltage poob nyob rau hauv lub piav ntau yam. Piv txwv li, 120 v - 277v ua ua haujlwm ntawm txhua qhov hluav taws xob nruab nrab 120 v ib 240v.

Ntawm no, puas yuav 277v ballast ua haujlwm ntawm 240v?

277V ballasts tsis txawm ua haujlwm zoo on 240 V , tsuas yog kev cia siab yog qhov ballast yog ntau tus kais, 120/208/240/ 277v ua los yog hloov cov ballast mus rau ib tug multi-kais.

Tsis tas li ntawd, qhov txawv ntawm 120v thiab 277v yog dab tsi? 208V yog qhov voltage nruab nrab theem ntawm 3-theem "Y" Circuit Court uas yog 120 V los ntawm nruab nrab mus rau tej kub. 480V yog qhov voltage nruab nrab theem ntawm 3-theem "Y" Circuit Court uas yog 277v ua los ntawm kub mus rau nruab nrab. Ua raws li 110V piv rau 120 V strangeness, motors npaj los khiav ntawm 480V peb theem feem ntau sau npe ua 440V.

Yog li ntawd, yuav ua li cas hloov 277v rau 120v?

Ib kauj ruam down transformer uas siv 277 Volts thiab tso tawm 120 V . Zoo meej rau hloov dua siab tshiab PL (pin-raws li) fixtures rau ntau npaum GU24 fixtures. Tsuas yog tshem tawm PL Ballast thiab txuas mus rau Kauj Ruam Down Transformer. Lub zog tuaj 277v ua thiab tawm mus 120 V.

Puas yog 277 zoo ib yam li 240?

Cov 240 volts yog ntsuas los ntawm kab mus rau kab thiab 120 volts yog ntsuas los ntawm ob kab mus rau nruab nrab lossis hauv av conductor. Lub 480 volts feem ntau yog rau cov motors thiab qee cov khoom siv thiab cov 277 volts yog siv rau teeb pom kev zoo. Yuav tsum muaj lub tshuab hloov pauv hauv cov tshuab no kom tau txais 120 volts rau cov khoom siv.
