Product Description

30KW UHF analog TV broadcasting equipment liquid-cooling

Characteristics:

l Standby redundancy design,eliminate single critical malfunction,high reliability and stability

l All solid state power amplifiers, modular design, tight structure, each function unit has clear boundary,

convenient maintenance and networking design.

l Various advanced precalibration function. DG, DP, group time delay, intermodulation etc. precalibration

circuits ensure better transmitter indicators than specified.

l Various function protections: high efficiency of power supply, wide range of voltage stabilizing, strong

ability of adjusting to grid change, protections are overvoltage, overcurrent, undervoltage, over temperature,

over heat, short circuit, anti-lighting, over exciting, overload, high SWR, lack-of-phase, non-video,

water pump malfunction, water pressure/water temperature alarm etc.

l High reliable control method: manual or automatic on/off system; automatic on/off system has remote

control and local touchscreen control.
