ZHC518A-200W TV Transmitter
Features:
The whole machine is single-channel, image with audio together.
The management and monitoring are intelligent and on network, it has the external PC interface.
It has the technical data detection, monitoring systems and full-featured computer control software with auto-diagnostic function. All technical parameters can be read through the LCD display panel.
Comprehensive protection measures can reduce the damage of equipments. This machine has protection about no video; VSWR is too large, overheating, over-stimulus, missing phase protection and lightning protection. The switch has protection about overvoltage, over current, under voltage, over temperature, short circuit and lightning protection.
All power supplies are switching power supplies; high efficiency, excellent regulator range, strong adaptable from the change of the external voltage.
It adopts modular design concept.
Hot-pluggable design: Power amplifier and switching power are supporting the Hot-plug, it's easy to debug and maintenance; improve the reliability.
The fan is built-in the chassis, the transmitter has a compact structure and a beautiful shape.
