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. WebFeb 2, 2024 · It's either dissipated in the transmitter circuit or directed back to the power supply through protection diodes. VSWR is not practical thing to be measured directly as the voltage ratio Vmax/Vmin at 10 MHz because one needs a half wavelength piece of open cable where the voltage amplitude between the wires is possible to measure at every point.

WebProtection is provided for both high SWR (preset to 2:1) and high temperature. The fans only run during transmit unless the heat sink gets above 110F, then the fans run continuously until the temp drops to about 105F. If the temp gets to 135F, the amp goes in to bypass. The fans are 50V units but we have wired them in series to reduce the noise. WebPRS provides detailed protection and control electrical designs for both new and retrofit installations.
