I use Eltec server power supplies for my SSPAs and up until now I have not
had an issue. I recently acquired a Larcan Hi-Hi that is capable of 1500
watts output on 222 MHz. After making the necessary changes to use the
Larcan I connected for testing to my 50V 3000 watt Eltec power supply. On
initial key down the amplifier easily puts out 1200+ watts but the supply
voltage drops significantly as does the RF output power. When running my
other amplifiers I do not have voltage drop and everything works fine.
I have tried this with 3 different power supplies. My assumption is I am
reaching the current limit of the individual supplies.
If each Eltec is set to the same voltage and current limiting, can I
parallel them? If so, is it any more complicated than connecting the
outputs together?
