1. Module design with reasonable structure and easy for installation and maintenance.
2. Computer monitoring system with the function of remote control and failure alarm.
3. Standby and redundancy design and can realize zero transmission stop.
4. Dual exciter and can be standby each other.
5. The power module has the protection function of over current, over voltage, balance, over VSWR, over exciting, over temperature etc.
6. Switch power module has various protection systems. Overall machine can monitor the operation of each power supply.
7. Cooling system uses low noise centrifugal blower that can effectively reduce the ambient noise.

We also manufacture TV solid state/FM stereo transmitter from 100W to 20KW, customer who has interest on our relevant product please don't be hesitated to contact for more information.
