Hloov pauv thiab Hloov pauv Qhov chaw. Me me transformers ntsaws rau hauv lub qhov hluav taws xob ntawm phab ntsa thiab tsim cov hluav taws xob ncaj qha tam sim no uas siv los ntawm cov khoom siv hluav taws xob ntau. Hloov pauv cov qhov hluav taws xob tau dav dav dua li lwm qhov chaw tawm kom haum transformer thaiv cov adapters los yog lwm yam adapters uas loj loj.

Raws li, lub plug nyob rau hauv chav kawm 2 transformer siv rau dab tsi?

Chav kawm 2 Cov Circuits Cov no yog cov ntawv siv qis tam sim no ua haujlwm ntawm 100VA lossis tsawg dua thiab 30 volts lossis tsawg dua. Hom chav kawm 2 circuits muaj xws li cua txias thermostats, garage door openers thiab sprinkler system tswj. A chav kawm 2 transformer yog siv muab chav kawm 2 circuits.

Tsis tas li ntawd, qhov txawv ntawm adapter thiab transformer yog dab tsi? Ib txhia adapters tsuas muaj ib transformer , thiab tso zis tsuas yog AC ntawm qee qhov hluav taws xob tsawg. Lawv tsis raug tswj hwm, yog li cov zis voltage nyob ntawm ob qho tib si input voltage thiab load. Qhov hluav taws xob ntawm daim ntawv lo tsuas yog qhov tseeb ntawm qhov teev input voltage thiab tso zis load.

Ntawm no, koj yuav ua li cas kuaj lub ntsaws rau hauv lub transformer?

Yuav ua li cas txheeb xyuas Transformer Nrog Multimeter

  1. Txuas lub transformer rau hauv lub qhov hluav taws xob.
  2. Tshawb xyuas lub transformer daim ntawv lo kom pom qhov twg ntawm lub jack yog qhov zoo thiab qhov twg yog qhov tsis zoo.
  3. Muab qhov zoo (liab) sojntsuam los ntawm lub multimeter ntawm lub ntsis ntawm lub jack thiab qhov tsis zoo (dub) sojntsuam ntawm qhov loj hauv cheeb tsam.
  4. Ceeb toom.

Class 2 AC adapter yog dab tsi?

Feem ntau, a Chav kawm 2 Circuit Court (ua haujlwm ntawm 24V nrog a zog muab khoom ruaj ruaj " Chav kawm 2 "thiab tsis pub tshaj 100VA) yog hom siv ntau tshaj plaws. Lub NEC txhais tau tias a Chav kawm 2 Circuit Court raws li qhov feem ntawm cov xaim hluav taws xob nruab nrab ntawm sab load ntawm a Class 2 zog qhov chaw thiab cov khoom siv txuas nrog.
