IIRC the APS-20 was about 2.4 MW Peak Pulse Power.
Might have been ERP, but I don't think so.

Maybe the last of the line, but the "classic" AN/APS-20 is 1 MW. I
don't have data on the -G version, and it very well could have
received a new transmitter and modulator.

Antenna rotation speed effects beam dwell time on target, and thus power
delivered to the target. Obviously in the extreme only one pulse would
hit the target before the beam moved on and thus probability of
detection would be minimized.

That is true, but as far as the power supplies are concerned, they
just see more juice going to the antenna drive.

Yes, I suppose so but the total of 160 kilowatts of primary
alternating current power available (and the 800 amperes at 28
VDC which was derived from that) likely wouldn't be much
concerned with the little bit of power required to drive the
antenna rotator I'd think...
