[Amps] High Voltage Switching Supply (Bob D.)

[Steve Harrison]

What you may have missed is that we're talking about industrial-strength
Panasonic high voltage inverters... i.e., switching power supplies used
with microwave ovens. Like in the 1500-watt range. Like in 2200V at
something like 700 mils. Not zactly chicken feed  8-)
