  • Details Introduction

ALL-SOLID-STATE 3KW/5KW AM TRANSMITTER

AM-3000/AM-5000


 
 
Features:

l       It adapts linear pulse width modulation. Computer auxiliary design.

l       Power uses voltage combined technology. Each amplifier module outputs > 600W.

l       Audio input port has audio processor. It improves listening result and guarantees the broadcast safety.

l       Display digital frequency , amplitude , input level etc.

l       Intelligent connector----- liquid crystal LED . Transmitter can test, control, diagnose , remember with this interface. It makes stability high and maintenance easy.  

l       Perfect protection functions: over-Pr, over-heat, three time over-load.

l       Good tank circuit design and anti-thunder.

l       Computer connector for monitor and control.

l       Rack use double aluminous shielding structure with radiation-proof function and corrosion protective device.

l       Simple structure, easy maintenance, reliable specifications, saves power and electricity.
