The SG-500 500W linear amplifier is ideal for high power operation in your base station or mobile installation.
The SG-500 is microprocessor controlled. It automatically monitors your power needs and selects the right broadband filter.
It also has the most advanced self-protection on the market, providing maximum reliability and unattended operation.
For maximum power, under the most demanding conditions, the SmartPowerCube is the professional's choice.

Continuous Operation Fan Kit
Remote Control ON/OFF Unit
The optional continuous operation fan kit for the SG-500 allows the user to operate at 500W PEP or CW under high stress conditions. The assembly is a 12VDC low profile fan attachment outside the amplifier. It is brushless and is activated automatically when heatsink or ambient temperature exceed 50 degrees C. The fan also extends the unit's operation from +70 to +85 degrees C ambient temperature under normal 500W PEP setting and allows continuous(24 hour) operation at 375W CW with a maximum room temperature of 35 degrees C.
This compact box permits convenient remote-control operation of the SG-500 amplifier and includes an ON/OFF switch with LED for visual indication of DC power. Supplied with the unit are 15 feet of control cable and required plugs for the panel connection to the amplifier. The detailed instructions included simplify installation and operation
