FMUSER CZH518A-3KW 3KW 3000W Analog TV Transmitter Professional VHF / UHF Analog TV Transmitter rau TV noj

CZH518A-3KW 3000W transmitter yog lub xeev ib leeg-channel VHF / UHF analog TV transmitter. Nws txais kev tshaj lij TV exciter thiab tau teeb tsa hauv 19-nti chassis, uas yog tsim rau txhua theem ntawm TV. Tsis tas li ntawd, ib leeg / ob chav actuator configuration tuaj yeem siv rau kev hloov pauv tsis siv neeg. Nws muaj cov haujlwm ntawm ntau cov kab thiab tsis-linear pre-correction, cab kuj zaus offset, thiab precision deviation (nrog rau lwm precision siv qhov chaw). Nws tuaj yeem prefabricate thiab tswj ib nrab lub zog tso zis thiab muaj cov chaw taws teeb tswj thiab telemetry interface. Lub hwj chim amplifier ua rau siv cov analog thiab digital tshaj LDMOS FET rau TV tshaj tawm. Nyob rau hauv cov nqe lus ntawm accessories, ib tug high-zoo hloov mus rau tib lub hwj chim mov yog siv. Lub hwj chim amplifier thiab cov khoom siv hluav taws xob siv cov khoom siv kub sib pauv. Lub vijtsam kov tseem ceeb qhia txog kev ua haujlwm ntawm tag nrho lub tshuab thiab lub zog amplifier (PA) module hauv lub sijhawm. Lub zog amplifier module tuaj yeem tso saib cov haujlwm tsis ua haujlwm hauv lub sijhawm. Tag nrho lub tshuab muaj dhau-tam sim no, dhau-kub, overpower, thiab sawv yoj piv tiv thaiv kev ua haujlwm. Yog li ntawd, lub zog poob thiab sawv nthwv dej ntawm ib qho hluav taws xob hluav taws xob ib zaug yog qhov me me, nrog kev poob qis thiab kev ua haujlwm siab.

zoo

CZH518F-3KW yog ib lub xeev ib leeg-channel VHF / UHF analog TV transmitter, duab, thiab suab ua ke.

Peb redundant configuration designs: exciter redundancy tsim, lub hwj chim amplifier redundancy tsim, fais fab mov redundancy tsim yuav txo tau inactive tus nqi mus rau xoom. Qhov no txhais tau hais tias thaum lub ntsiab exciter tsis ua haujlwm, nws tuaj yeem hloov mus rau qhov standby exciter tsis tu ncua; Ntau lub zog amplifiers tau sib xyaw ua ke, thiab lub zog amplifier modules zoo sib xws.

Ob lub exciters yog standby rau ib leeg thiab yog ib qho yooj yim los hloov; lawv tau muab los ntawm ntau yam khoom siv hluav taws xob hloov mus rau qhov sib npaug, thiab lub khoos phis tawj tuaj yeem saib xyuas thiab hloov kho lub sijhawm ua haujlwm ntawm lub zog hluav taws xob.

Kev tswj hwm ntse thiab kev saib xyuas, nruab nrog lub network sab nraud PC interface. Kev ua haujlwm puv computer tswj software, nrog kev kuaj mob tsis siv neeg, kev tshawb nrhiav cov ntaub ntawv, kev saib xyuas, thiab lwm yam haujlwm.

Cov kev tiv thaiv kev tiv thaiv kev hloov pauv los ntawm lub tswv yim tsim qauv tuaj yeem txo cov khoom puas tsuaj. Lub tshuab no tsis muaj kev tiv thaiv video; voltage sawv yoj piv yog loj heev, overheating, tshaj excitation, tsis muaj theem tiv thaiv, xob laim tiv thaiv.

Tshaj-voltage, tshaj-tam sim no, under-voltage, tshaj-kub, luv-circuit, thiab xob laim tiv thaiv. Nyob rau tib lub sijhawm, tag nrho cov kev ntsuas tsis tuaj yeem nyeem los ntawm LCD. Tag nrho cov khoom siv hluav taws xob hloov pauv cov khoom siv hluav taws xob nrog kev ua haujlwm siab, kev hloov kho dav dav, thiab muaj peev xwm hloov tau rau cov kev hloov pauv sab nraud. Qhov kub-swap tsim ua rau lub zog amplifier thiab hloov hluav taws xob hloov pauv hloov pauv, uas yooj yim rau kev debugging thiab txij nkawm, thiab txhim kho kev ntseeg tau.

Compact qauv thiab zoo nkauj tsos, nrog ib tug muaj zog cua txias built-in kiv cua.
