My K3S does show the voltage and current on its display. In receive it
nominally is 13.8 volts and 1.05 amps. For transmit, CW mode key
closed 100 watts output the current is 18.5 amps. Both of these values
concur with my power supply metering.
I've experienced no shut down while operating JT-65 or more recently
FT-8. For JT-65 I normally set the PWR to 50 watts. For FT-8, being a
shorter transmit time, although duty cycle is the same as JT-65 or about
50%, I do sometimes run 100 watts. More often I find 25 to50 watts to be
most adequate.

Buddy/Mike, further to my earlier email the current on receive is
actually 1.05A as measured on a digital multimeter and not 5A as
indicated on the PSU analogue meter.
Of course this doesn't solve the immediate problem.
