Oscar,
I don't know the specifics of your particular amplifier - BUT -
The K3 KEYOUT can handle up to 200 volts DC (positive only) at 5 Amperes.
You can easily measure the requirements of any amplifier
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

You can easily measure the requirements of any amplifier with a DMM.
First set it to read voltage and measure the open circuit voltage (to

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
Tom,
You are correct, peak currents are difficult for the average amateur to
measure. So perhaps a rule of thumb might be that the steady-state
current should be no higher than 500 ma. would be good for the K3 - I
doubt that peak currents would exceed 5 A if there is only 500 ma
