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.
● The fan is built-in the chassis, the transmitter has a compact structure and a
beautiful shape.
