[Elecraft] KPA 100 Power requirements

[Stephen W. Kercel]

I am considering the purchase of a K2 kit with the 100 watt amplifier. I 
have several questions about power requirements:

Is the Astron RS-35 series adequate to power the 100 watt version of the 
transceiver? (I'm sure it supplies enough current. I was wondering if the 
ripple and regulation are adequate.)

I would like to put a circuit breaker between the power supply and the 
transceiver. Does anyone have any recommendations as to current rating and 
operating speed? Preferably, is there a specific manufacturer and model 
that is considered best suited to the task? Is a circuit breaker actually 
necessary, or am I simply succumbing to the temptation to gild the lily? I 
am considering a Potter and Brumfield W31-X2M1G-25, but I wonder if it 
might be too slow.

I am also thinking to install an EMI filter between the power supply and 
the transceiver. The one I have in mind is the Spectrum Control 54-848-005, 
rated at 50 amps and with an insertion loss of 30 dB at 3 MHz. (The down 
side is that the filter costs a bit over $100.) Is this a good idea, or am 
I attempting to solve a problem that does not arise in the K-2/KPA100.

What kind of power connector do I need to make up the high power DC 
connection to the K-2?

Thanks and 73,
