Product Description

KFS-Ⅱ Broadcast Equipment 2KW Digital TV Transmitter UHF Wireless TV Coverage, is the fourth generation of terrestrial digital broadcasting TV transmitting equipment.

Main Features:

1. Supports MFN and SFN modes, SFN mode compliant with GY/T 229.1-2008.

2. All-solid-state with modularization structure;

3. Dual exciter systems, the active and reserve exciter can be switched manually or automatically. Keep consistent work state when switching.

4. Adopts advanced adaptive pre-distortion correction technique, big correction value, improved transmitter parameters and efficiency;

5. Adopts advanced LDMOS as power amplify tube, better index, higher efficiency and smaller bulk.

6. Independent designed cross coupling 6-cavity filter, the output spectrum meets China standard;

7. Transmitter has multiple protection measures against losing lock, overheating, standing wave, inter lock and overloading to ensure stable work status.

8. Local/Remote monitoring and On/Off schedule for unattended operation.

9. Embedded microcomputer monitor system, large color LCD touch screen, to ensure real-time monitoring of the transmitter.

10. RS485 interface for remote metering and remote control.

11. Optional air cooling or water-cooling, for different station requirements.
