Low-power Transmitter
La cuarta generación de la serie de transmisores de TV digital de baja potencia se basa en años de investigación y desarrollo de tecnologías acumuladas. Los productos soportan las normas DVB-T / H, DVB-T2, DTMB, CMMB, ISDB-T y ATSC-T, entre otras. Hasta el presente, tenemos varios casos comerciales exitosos con alta estabilidad. El Tiempo Medio Entre Fallas (MTBF) es superior a 13.800 horas.
Low-power transmitter family provides wide power range, from 350W up to 2kW. Support VHF and UHF bandwidth. Supports variety of terrestrial digital standards, such as DVB-T / H, DVB-T2, ATSC -T, ISDB-T, DTMB, CMMB and other standards. And we provide dual driver or single driver configurations.
Products adopt N+1 redundancy and dual exciters configuration, ensure the equipment stability, and the MTBF over 13,800 hours, MTTR is less than 15 minutes.
Support for high-efficiency liquid cooling system and air cooling system to ensure safe and effective. And the cooling mode can be configured according to user requirements, with flexible and varied.
Supports multiple power supply (208V/220V/240V/380V/400V/440V/480V), the equipments can be working in multiple situation.
The power amplifier module adopts the latest R&D 50VDC LDMOS devices, highly integrated, can save energy 15% than general transmitter.
Low-power transmitter family supports SNMP and Web Server monitoring, and remote software upgrades.
Support dual channel ASI interface, RJ45 interface, IP interface, GPS antenna input interface, etc.
The products provide over-heating, over-voltage, over-current, lightning and other protective measures. And we provide the system with comprehensive security, and the products meet the CE marking and RoHS environmental standards, etc.
