  • Details Introduction

ALL-SOLID-STATE 25KW AM DAM TRANSMITTER       

AM-250000

1. Improved cycle modulation techniques. Computer auxiliary design.

2. Power uses voltage combined technology. Same power amplifier modules are  used . It makes structure very simple and maintenance easy. Full redundancy in the modulation principle

3. Reliable design of lightning protection. Finishing you to damage the machine to the thunder stroke worrying.

4. Convenient power setting. Modulation capacity can be 140%.

5. Microcomputer controlling system and LED displays to realize automatically open, close down, data record, memory, graduation monitoring functions etc.

6. Computer and remote ports are available for monitoring and controlling.

7. Sync. Radio exciter space and external exciter signal input are reserved for future purpose.

8. The essential primary device uses import, selects strictly component pass

9. Whole efficiency: > 85%

10. Reliable specifications, saves power and electricity.
