Ltalis EKA PLL / CST-3 250W LCD FM Transmitter

1-13011G50G9610

Phase-kaw lub voj voos yog lub xov tooj cua FM transmitter 87.6-107.9MHZ ntsuas phoo.

Txhawm rau kom tau tshaj txhua lub teeb liab audio, lub ntaus ntawv muaj plaub lub tswv yim.

Txig tawm lub tswv yim ib qho multiplexed channel thiab txoj cai channel, sab laug channel sib txuas teeb liab multiplexed ua ke thiab txuas rau ob lub cim xa khoom.

Mono cov tswv yim suav nrog txoj cai hla qis, tawm ntawm 20K-100KHZ teeb liab attenuation tshaj 15KHZ 30dB.

Qhov ntsuas hluav taws xob rau txhua lub teeb liab nkag mus ua kom tiv thaiv qhov sib txawv ntau tshaj yog ± 75KHZ.

Phase-kaw lub voj voos siv cov txheej txheem ntawm micro stepper maub los 10K-100KHZ's.

Ntxiv rau qhov zaus, tab sis kuj tsis tso cai rau qhov nrhiav kom tau ntawm cov pab pawg teeb, cov zaub zaus thiab kev tswj hwm thiab kev tiv thaiv ntawm lub zog kawg theem muaj lub zog transistor amplifier, lub zog siv hluav taws xob tuaj yeem ncav cuag 250W.

Rack, 3U cov cuab yeej siab tsim los ua "19" hauv kev sib dhos, nws tuaj yeem tshem tawm kom paub tseeb tias cov qauv sab hauv ntawm lub vaj huam sib luag, txhawm rau kom haum rau lub zog loj tau xaiv tau 220V lossis 110V.

Cov Chaw: Yog tias koj xav tau muab cov transmitter nrog lub tso suab encoder.

Kev khiav hauj lwm

Ntawm lub transmitter pem hauv ntej vaj huam sib luag muaj LCD tso saib ntaus cim tsis raug, thiab plaub lub luag haujlwm rau kev teeb tsa parameter, teeb tsa zaus thiab hloov suab stereo encoder.

Thaum koj tig rau lub transmitter qhia cov lus qhia hauv qab no:

Cov ntsiab lus, F2 thiab F3 kom xaiv cov zaub xa tau thiab muaj hwj chim, emission zaus, ntaus ntaus ntawv, khoom npe, thiab sab laug thiab sab xis channel audio voltage.

F1 thiab F4 yuam sij tuaj yeem ua hom programmed, kev ua haujlwm tau piav qhia raws li hauv qab no:

Txhawm rau hloov qhov hloov zaus kom nkag mus rau hom kev sau, nias F1 thiab F4 rau

Siv F2 lossis F3 khawm los xaiv "Tso zis rau zaus" xaiv thiab paub meej tias nias F4. Nrog F2 thiab F3 yuam sij los teev qhov zaus.

Tshaj tawm cov txheej txheem programming, nias F4 txhawm rau tsim cov chaw tshiab, nias tus yuam sij F1 tsis cia. Txhawm rau qhib lossis kaw lub stereo module, tom qab ntawd nias F1 thiab F4 yuam sij, tom qab ntawd siv F2 lossis F3 los xaiv "Stereo Module" xaiv. Paub meej tias nias F4.

"Qhib Stereo Module" lossis "tawm ntawm stereo module" nrog F2 lossis F3 los xaiv, ces nias F4 kom paub meej. Yog tias lub tshuab tsis tau suab cov qauv, qhov kev teeb tsa no tsis raug.

Nyob rau hauv kev ua haujlwm txawv txav tsis zoo, tib cov lus ceeb toom tau tshwm tawm, cov ntsiab lus ntawm kab thib ob ntawm cov zaub:

1. ”Hloov lub tswb hluav taws xob” thaum lub zog tso zis hluav taws xob ntau dua 250W

2. "Reflected Fais Fab Tswb" nyob rau hauv cov ntaub ntawv ntawm lub hwj chim rov los tshaj 30W

3. ”Theem-Xauv Lub Voos tsis ua lub tswb” Lub voj puas yuav ua haujlwm

Tib lub sijhawm tso tawm cov lus qhia saum toj no, cov xwm txheej hauv qab no:

1. Lub zog tsim hluav taws xob ntau yog txwv rau 250W

2. Reflectivity yuav paub txog lub zog reflected tsis dhau 30W

3. Ua haujlwm RF tso zis module yog inhibited

Xws li qhov kub thiab txias, "Tswb Ntsuas Kub" LED yuav ua kom sib, thaum kawg yuav ua rau pom kev.
