Lub luag haujlwm tseem ceeb ntawm optocoupler hauv Circuit Court yog cais thiab hloov photoelectricity, thiab muaj ntau yam kev siv, yog li optocouplers kuj muaj ntau hom, uas tuaj yeem muab faib ua ntau hom raws li kev faib tawm sib txawv, thiab cov txheej txheem kev faib tawm ntawm optocouplers yog:
1. Raws li txoj kev kho qhov muag
Nws tuaj yeem muab faib ua ib qho kev kho qhov muag sab nrauv photocoupler (tseem hu ua photointerrupted detector) thiab ib qho kev kho qhov muag sab hauv photocoupler. Sab nraud optical path photocouplers tau muab faib ntxiv rau hauv kev xa tawm thiab kev cuam tshuam photocouplers.
2. Raws li daim ntawv tso zis
(1) Photosensitive ntaus ntawv tso zis hom, suav nrog photodiode tso zis hom, phototransistor tso zis hom, photocell tso zis hom, photocyristor tso zis hom, thiab lwm yam.
(2) NPN transistor tso zis hom, suav nrog AC input type, DC input type, complementary output type, thiab lwm yam.
(3) Darlington transistor tso zis hom, suav nrog AC input hom thiab DC input hom.
(4) Logic gate output type, nrog rau qhov rooj tso zis hom, Schmitt trigger output type, peb lub xeev qhov rooj tso zis hom, thiab lwm yam.
(5) Tsawg conduction tso zis hom (tso zis theem millivolt kev txiav txim ntawm magnitude).
(6) Optical switch output type (on-resistance tsawg dua 10Ω).
(7) Fais fab tso zis hom (IGBT / MOSFET tso zis).
3. Raws li daim ntawv ntim khoom
Nws tuaj yeem muab faib ua hom coaxial, ob hom kab hauv kab, TO pob hom, hom pob tiaj tus, SMD pob hom, thiab hom fiber ntau kis tau tus mob.
4. Raws li cov teeb liab kis tau tus mob
Nws tuaj yeem muab faib ua digital optocoupler (OC gate output type, totem pole output type and three-state gate circuit output type, etc.) thiab linear optocoupler (yuav muab faib ua hom qis drift, high linearity type, broadband type, single power. hom khoom, dual fais fab mov hom, thiab lwm yam).
5. Faib raws li ceev
Nws tuaj yeem muab faib ua photocoupler uas tsis tshua muaj siab (tso zis hom xws li phototransistor thiab photocell) thiab high-speed photocoupler (photosensitive diode nrog lub teeb liab ua Circuit Court lossis photosensitive integrated circuit output type).
6. Raws li channel
Nws tuaj yeem muab faib ua ib-channel, dual-channel thiab ntau-channel optocouplers.
7. Raws li cov yam ntxwv ntawm kev sib cais
Nws tuaj yeem muab faib ua qhov sib cais zoo tib yam optocoupler (tuaj yeem muab faib ua 10kV, 20kV, 30kV, thiab lwm yam).
8. Raws li kev ua haujlwm voltage
Nws tuaj yeem muab faib ua qhov hluav taws xob qis hluav taws xob hom optocoupler (feem ntau 5 ~ 15V) thiab lub zog hluav taws xob siab voltage hom optocoupler (feem ntau ntau dua 30V).
