Characteristics of FM Transmitter
- Apr 02, 2018 -

• Full solid state circuit design, good stability, high reliability.

• The actuator adopts imported, excellent quality, good performance, and has SCA, RDS interface.

• Power amplifier modules are imported high-power field effect tube, high efficiency, large redundancy, interchangeability strong.

• High-stability, efficient power supply system, all current power supply.

• With Overvoltage, over-current, overheating and standing wave than large protection function, safe and reliable work.

• Multiple lightning avoidance systems.

• Embedded computer monitoring system, good Man-machine interface, intuitive large-screen LCD display,

With RS485 parallel communication interface, remote telemetry and remote control can be realized.

• According to the need, can be configured with dual-actuator, and automatic switching.

• Forced air-cooled, small power consumption, low noise.

• The whole machine adopts general standard cabinet, component type structure, beautiful and elegant shape.

• The indicators are superior to the ministerial Class A standard.
