FMUSER CZH518A-3KW 3KW 3000W Analog TV Transmitter Professional VHF/UHF Analog TV Transmitter yezviteshi zveTV.

CZH518A-3KW 3000W transmitter is solid-state single-channel VHF/UHF analog TV transmitter. Inotora nyanzvi yeTV exciter uye yakaiswa mu 19-inch chassis, iyo inokodzera mazinga ese eTV. Uye zvakare, single/double actuator kumisikidzwa inogona kushandiswa otomatiki switching. Iyo ine mabasa eakawanda mutsara uye asina-mutsara pre-kururamisa, mutakuri frequency offset, uye chaiyo kutsauka (neyekunze chaiyo referensi sosi). Inogona kugadzira uye kutonga hafu-simba kubuda uye ine kure kure control uye telemetry interface. Iyo magetsi amplifier inoshandisa analog uye dijitari inoenderana LDMOS FET yekutepfenyura paTV. Panyaya yezvishandiso, yemhando yepamusoro switch parallel magetsi inoshandiswa. Iyo magetsi amplifier uye magetsi ekushandisa anoshandisa inopisa-chinja-chinja michina. Iyo huru yekubata skrini inoratidza inoshanda ma paramita emuchina wese uye iyo simba amplifier (PA) module mune chaiyo-nguva. Iyo simba amplifier module inogona kuratidza iyo inoshanda paramita mune chaiyo-nguva. Muchina wese une pamusoro-ikozvino, pamusoro-tembiricha, kuwandisa, uye kumira wave ratio kuchengetedza mabasa. Naizvozvo, kurasikirwa kwesimba uye kumira kwakamira kweimwe-nguva synthetic simba synthesizer idiki kwazvo, nekurasikirwa kwakaderera uye kugona kwakanyanya.

Advantages

CZH518F-3KW yakasimba-nyika imwe-chiteshi VHF / UHF analog TV transmitter, mufananidzo, uye odhiyo pamwechete.

Matatu matatu akadhinda dhizaini dhizaini: exciter redundancy dhizaini, simba amplifier redundancy dhizaini, magetsi ekupa redundancy dhizaini inogona kuderedza isingaite chiyero kusvika zero. Izvi zvinoreva kuti kana iyo huru exciter ikakundikana, inogona kushandura kune yakamira exciter nguva dzose; akawanda masimba amplifiers akabatanidzwa, uye iwo ma module emagetsi anopindirana zvakanyanya.

Iwo maviri exciters akamirira kune mumwe nemumwe uye ari nyore kutsiva; ivo vanopihwa neakawanda ekuchinja magetsi emagetsi akafanana, uye komputa inogona kutarisa uye kugadzirisa otomatiki mamiriro ekushanda emagetsi.

Hungwaru manejimendi uye yekutarisa sisitimu, yakashongedzerwa neyekunze network PC interface. Yakazara basa komputa inodzora software, ine otomatiki kuongororwa basa, tekinoroji data yekuona, yekutarisa system, uye mamwe mabasa.

Iwo akasanganiswa ekudzivirira matanho akashandurwa kubva kune modular dhizaini pfungwa anogona kuderedza kukuvara kwemidziyo. Muchina uyu hauna kudzivirira kwevhidhiyo; voltage stand wave ratio yakakura kwazvo, kupisa, kuwedzeredza, kushaikwa kwechikamu chekudzivirira, kudzivirira mheni.

Over-voltage, over-current, under-voltage, over-temperature, short-circuit, uye kudzivirira mheni. Panguva imwecheteyo, ese tekinoroji paramita anogona kuverengwa kuburikidza neLCD. Ese magetsi ekushandisa ari kushandura magetsi emagetsi ane hunyanzvi hwepamusoro, hupamhi hwekugadzirisa huwandu, uye kugona kwakasimba kuchinjika kune ekunze magetsi ekuchinja. Iyo inopisa-chinjana dhizaini inoita iyo magetsi amplifier uye kushandura magetsi ekutsigira kupisa-chinjana, iri nyore kugadzirisa uye kugadzirisa, uye inovandudza kuvimbika.

Chimiro chakasimba uye chitarisiko chakanaka, chine kutonhora kwakasimba kwakavakirwa-mukati fan.
