XA500 – 500W
The XA500 is a very high specification FM power amplifier that uses the latest design and construction techniques, to provide high performance, excellent control/monitoring and maintenance free use in only 3U and 22kg. The XA500 is a wideband design requiring no tuning and offers very easy installation. In common with EBL’s entire power amplifier range the XA500 uses EBL’s world renowned heat dissipating “fresh-air-tunnel” concept with dual fans. The fans provide cooling to the specially designed heat sink with a stream of air that needs no filtering saving on routine filter replacements. Minimal active components are in the air flow thus keeping sensitive areas free from dust and contaminants. For the harshest of environments that demand additional air filtering, clip on filter kits are available that attach to the exterior of the PSU and RF sections of the XA500.
System Overview
The XA500 employs 2 hot pluggable front panel high specification switching type power supplies. These telecoms grade units with a proven track record of high reliability in harsh and hostile areas. The XA500 front panel LCD display shows forward and reflected power together with internal voltages, and temperature’s. Quick view LED’s show advanced status information including CPU ok, system normal and external mute. The rear panel includes a remote control/monitoring socket that allows carrier muting and status signalling to an external system, additionally data sockets are provided for use with systems that have the ability to control exciters via RS232 or TCP/IP. Very conservatively rated components with switch mode power supplies are used to ensure extremely high reliability and to give good efficiency.
