Product Description

10KW VHF analog TV broadcasting equipment Liquid-cooling

Characteristics:

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

l All solid state power amplifier, 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: protections are overvoltage, overcurrent, undervoltage, over temperature, over heat, short circuit, anti-lighting, over exciting, overload, high SWR, lack-of-phase, non-video, waterpump 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.
