Voltage ndi Current Universal Transformer
01
TVA1421 Series Miniature Precision AC Voltage ndi Zosintha Zamakono
Mawonekedwe
① Itha kugwiritsidwa ntchito ngati chosinthira magetsi kapena chosinthira chapano.
② Imatha kuwotcherera mwachindunji pa PCB.
③ Ndi yolondola kwambiri, ili ndi zitsanzo zambiri, ndipo imasinthasintha pamagwiritsidwe ake.
④ Imatsekedwa mokwanira, ili ndi chipiriro champhamvu pamakina ndi chilengedwe, mphamvu yamphamvu ya dielectric, ndi ndondomeko yokongola.
Ambient Conditions
① Kutentha kozungulira: -55℃～+85℃;
② Chinyezi chachibale: ≤90% pa 40 ℃;
③ Kuthamanga kwa mumlengalenga: 860 ~ 1060mbar (pafupifupi 650 ~ 800mmHg).
Mtundu wa Frequency Range
20Hz ~ 20kHz
Kalasi ya Insulation Thermal
Kalasi B (130 ℃).
Chitetezo Mbali
① Kukana kwa dielectric: > 1000MΩ m'malo abwinobwino;
② Insulation kupirira ma voltages: 3KV 50Hz/1min (yomwe imagwiritsidwa ntchito ngati chosinthira magetsi);
6KV 50Hz/1min (yomwe imagwiritsidwa ntchito ngati thiransifoma yamakono);
③ Kuchedwa kwamoto: Mogwirizana ndi UL94-V0.
