- The whole machine is single-channel, image with audio together.
The redundant configuration design can reduce the rate of inactive to zero.
- The exciter redundancy design: the main exciter and its spare exciter can switch automatically (the spare exciter is optional). When the main exciter broke down, it can switch to the spare exciter uninterrupted.
- The power amplifier redundancy design: multiple amplifiers integrated; the modules of PA are high-consistency. These two exciters are the spare one with each other and can exchange easily.
The power supply redundancy design: parallel current sharing power from multiple switching power supply; the computer can monitor power supply’s working condition and adjust its working condition automatically.
- 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.
