Watch out using a steady-state meter to measure amplifier currents! The 2100Z is a good example of a very odd circuit.
The FL2100Z has positive relay voltage. It has a peak relay closure current surge of about 500-600 mA (that settles lower) and about 16-18 volts open circuit without much backpulse. It should be good for direct keying with the Elecraft K3 if the K3 will take 5 amps. The regular FL2100 has negative relay voltage. No good on the FL2100. > oscarv...@speedy.com.ar wrote: >> I need to connect my amplifier fl2100z with K3, direct >> connect to key out to RY the amp FL2100Z or I have to >> put a relay, please i need help and thank you very much.- >> >> LU1XS, Oscar >> >> > ______________________________________________________________ > Elecraft mailing list > Home: http://mailman.qth.net/mailman/listinfo/elecraft > Help: http://mailman.qth.net/mmfaq.htm > Post: mailto:Elecraft@mailman.qth.net > > This list hosted by: http://www.qsl.net > Please help support this email list: > http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
