Kev ntsuas ntau ntawm tus cwj mem xeem
Qhov ntsuas hluav taws xob ntau ntawm cov cwj mem uas tsis tshua muaj hluav taws xob zoo tib yam yog nyob nruab nrab ntawm 60-500V.
Thaum qhov hluav taws xob qis dua 60V, lub neon raj ntawm lub cwj mem hluav taws xob yuav tsis tawm lub teeb; rau qhov voltages siab tshaj 500V, nws yog nruj me ntsis txwv tsis pub siv ib tug zoo tib yam low-voltage xeem cwj mem los ntsuas kom tsis txhob muaj hluav taws xob shocks.
