WebInternal protection circuits automatically protect the ALS-600 from improper operation, high SWR, or high heat-sink temperature. The ALC interface can be customized for any transceiver through a rear-panel adjustment control. Finally, accurate cross-needle meters read SWR/Peak Power on the amplifier, and voltage/current on the power supply. WebThis brings up another point: By the time the SWR protect circuit detects high reflected power, there has been - for a brief instant- much higher power - It takes a finite amount of …
WebThe High SWR (RFP) alarm is telling. There are two independent, directional coupler circuits in the PGXL. One, serviced by the primary microprocessor, monitors power and return loss between the antenna and the amplifier. The second, by an (RF Protection) RFP microprocessor, monitors from the PA MOSFET perspective. http://www.ka7oei.com/ft817_vswr.html
