FMUSER CZH518A-3KW 3KW 3000W Analogi TV Transmitter Professional VHF/UHF Analogi TV Transmitter yama TV

CZH518A-3KW 3000W transmitter ndi njira yolimba ya VHF/UHF ya analogi TV transmitter. Imatengera akatswiri osangalatsa a TV ndipo imayikidwa mu 19-inch chassis, yomwe ili yoyenera pamagulu onse a TV. Kuphatikiza apo, kasinthidwe ka single/double actuator itha kugwiritsidwa ntchito posintha zokha. Imakhala ndi ntchito zowongolera mizere yambiri komanso yosagwirizana ndi mzere, kuwongolera pafupipafupi, komanso kupotoza kolondola (ndi gwero lazakunja). Ikhoza kupangiratu ndikuwongolera mphamvu ya theka la mphamvu ndipo imakhala ndi mawonekedwe akutali ndi mawonekedwe a telemetry. Chokulitsa mphamvu chimagwiritsa ntchito LDMOS FET ya analogi ndi digito yowulutsa pa TV. Pankhani ya zowonjezera, chosinthira chapamwamba chamagetsi chofananira chimagwiritsidwa ntchito. Magetsi amplifier ndi magetsi amagwiritsa ntchito zida zosinthira kutentha. Chophimba chachikulu chokhudza chimawonetsa magawo ogwirira ntchito a makina onse ndi gawo la amplifier mphamvu (PA) munthawi yeniyeni. Magetsi amplifier module amatha kuwonetsa magawo ogwirira ntchito munthawi yeniyeni. Makina onsewa ali ndi ntchito zachitetezo chanthawi yayitali, kutentha kwambiri, kupitilira mphamvu, komanso chitetezo choyimirira. Choncho, kutayika kwa mphamvu ndi kuyimirira kwa nthawi imodzi ya synthetic power synthesizer ndi yaying'ono kwambiri, ndi kutayika kochepa komanso kuchita bwino kwambiri.

ubwino

CZH518F-3KW ndi njira yolimba ya VHF / UHF ya analogi ya TV, chithunzi, ndi mawu pamodzi.

Mapangidwe atatu osasinthika: kapangidwe ka exciter redundancy, kamangidwe ka amplifier redundancy, kapangidwe kamagetsi kamagetsi kumatha kuchepetsa kuchuluka kwa ziro. Izi zikutanthauza kuti pamene exciter yaikulu ikulephera, imatha kusinthira ku standby exciter mosalekeza; ma amplifiers angapo amaphatikizidwa, ndipo ma module amplifier amphamvu amafanana kwambiri.

The exciters awiri ndi standby kwa wina ndi mzake ndi zosavuta m'malo; amaperekedwa ndi magetsi osinthika kangapo mofananira, ndipo kompyuta imatha kuyang'anira ndikusinthiratu momwe magetsi amagwirira ntchito.

Dongosolo lanzeru loyang'anira ndi kuwunika, lomwe lili ndi mawonekedwe akunja a PC network. Pulogalamu yathunthu yoyang'anira makompyuta, yokhala ndi ntchito yodziwikiratu, kuzindikira zaukadaulo, makina owunikira, ndi ntchito zina.

Njira zotetezera zophatikizika zomwe zimasinthidwa kuchokera ku lingaliro lopanga modular zimatha kuchepetsa kuwonongeka kwa zida. Makinawa alibe chitetezo chamavidiyo; Voltage stand wave ratio ndi yayikulu kwambiri, kutenthedwa, kutenthedwa, kusowa kwa chitetezo chagawo, chitetezo cha mphezi.

Kuchuluka kwamagetsi, kupitirira-panopa, kutsika kwamagetsi, kutentha kwambiri, kufupikitsa, ndi chitetezo cha mphezi. Nthawi yomweyo, magawo onse aukadaulo amatha kuwerengedwa kudzera pa LCD. Mphamvu zonse zimasinthira magetsi pogwiritsa ntchito mphamvu zambiri, kusintha kwakukulu, komanso kuthekera kolimba kuti agwirizane ndi kusintha kwamagetsi akunja. Kapangidwe kakusinthana kotentha kumapangitsa chokulitsa mphamvu ndi kusintha kwamagetsi kuthandizira kusinthana kwamagetsi, komwe kumakhala kosavuta kuwongolera ndi kukonza, komanso kumapangitsa kudalirika.

Kapangidwe kakang'ono komanso kawonekedwe kokongola, kokhala ndi chotenthetsera chozizira chokhazikika.
