  • Considered various application environment and conditions, and the device is designed with high reliability to realize all-weathers and unattended and nobody monitor.
  • With high-power broad frequency band synthesis technology, adopted LDMOS high-power FET of power amplifier module, the devices redundancy is high. Nonlinear feed correction technology, make the device extremely high linear and reliable.
  • ALC circuit guarantees power output stable, which ensures the stability, reliability and excellent performance of device.
  • Intelligentized controlling and remote monitoring functions, could configure and monitor equipment parameters through RS-232 interface support SNMP protocol optional. With GSM message autoalarm module, and fixed timing starting up and shutdown functions.
  • Casting aluminum alloy body, with outdoor style, windproof, rainproof and lightning proof functions.
  • Alarming and monitoring functions, which could be displayed by LED in front panel.
  • Wide voltage stability range and high efficiency of power supply.
  • With over-voltage, over-current, over-heat, over-excitation, low-voltage, absent-phase, short-circuit and over-VSWR auto-protective functions; with multiple-measure of thunder-proof, it could run securely.
