Bypass Power Limit

James Eastham Jr

Is there a power limit that you should not exceed through the PGXL power input and output when the Amp is in bypass mode or the amp is turned off (also bypass mode?

@James Eastham I'd be most concerned with the RF input since it designed for 100W exciter. With that said, I would not put more than 100W into the amp in bypass mode.

Depends on SWR. Generally when we ask what is the power limit, what really matters is the peak voltage or current. Many devices (especially passive ones like a tuner) fail by arcing over if there's too much voltage. Or, more rarely, they will overheat (melt, smoke) if they have to carry too much current.

If you're feeding anything other than 50 ohms, possibly an open circuit or short circuit, you're likely to run into a voltage or current limit, even at moderate power levels.

So I expect the amp or tuner bypass circuit is limited to "power" well below 2 KW when feeding a high-SWR load.
