The Legend 10,000C is built utilizing a “building block approach”. The
basic building block is a conservatively rated 1kW PA drawer. These
PA’s are then combined together to achieve the rated transmitter power
Internally each PA contains four mosfets
mounted on copper plates, which in turn are mounted on a massive heat
sink. This system of heat dissipation along with our exhaust fans
ensure cool operating temperatures for extended life.
16-18 watts of RF drive is required to achieve the 1kW PA output with each device output being combined by a 4:1 combiner.
Cooling is achieved by having filtered air enter the cabinet through
the front filtered door. This air is forced by independent muffin fans
to pass through the fins of the heat sinks upon which the mosfets are
mounted. This air is then forced out of the rear and exhausted out of
the cabinet by a number of 4” fans located on the rear doors.
The Legend 10,000C has a straight forward, easy to use control system.
It can be started by local or remote control. Simply initiate the start
button and within seconds you will be on the air.
Remote Control: No special interface is required. Simply apply a momentary ground to start, stop and reset the equipment.
Circuit Breaker & Fuse Protection:
Each PA contains a circuit breaker for the incoming DC power. Front
panel indicator lights describe the status of all circuit breakers.
Power Supply: The Legend 10,000C is powered by a brute force power supply located in a vault.
