DTV-100W/200W300W/400W

DTV Transmitter

Features:

• This transmitter family supports China Standard DTMB (GB20600-2006), CMMB and DVB-T, as well as UHF whole wave-band. And it is compatible with various exciters
• New wind channel design applied in forced air cooling system makes it easy to install and maintain, and achieve a best cooling result.
• Both Manual Level Control (MLC) and Automatic Level Control (ALC) are available
• Perfect protection against over-heat, over-current, over & under voltage, input & output over-power, reflection over range, phase failure, lightning and etc. Ultra-speed RF protection circuit ensures the reliability and safety of the amplifier;
• Modularization design in power amplifier unit: 100 W amplifier unit includes one final-stage power amplifier module (2 amplifying tubes, ID: MRF6VP3450), 200 W amplifier unit includes one final-stage power amplifier module (2 amplifying tubes, ID: BLF888A), 300 W/400 W amplifier unit includes three final-stage power amplifier modules (6 amplifying tubes, ID: MRF6VP3450). Inside is integrated imported hot-swappable power supply with auto-speed-regulating fans.
• Main detecting parameters are displayed on LCD screen of the amplifier unit and alert information is showed by LED status lights;
• Remote monitoring function can be applied to set, control and monitor the transmitter’s working status in remote or local mode.
• Specialized digital TV output filter is available per order.
