Power supply question

[KM3F]

For those who 'have done it', you lucky.
No regular supplies are designed to just connect togather unless one is designated as the control and a control line is connected to each.
Here are some reasons why;
They must load share equally or one tries to provide the larger current it was not designed to do.
Each supply has it's own regulation control circuit and cannot regulate to a load that includes other supplies trying to do the same.
If the output voltages are not the same under varying load conditions there is a dynamic missmatch in output regulation by each supply.
Don't kid yourself., what you think is the same supply does not always work exactly the same under load due to tolerences, like anything else.
Not a good idea to do.
Good luck.

kenwood's ts480hx @ 200 watts uses either 1-41 amp ps or 2-20 amp ps's. they divided the amplifier section of the radio into 2 halves to power each half individually. they tell you to use 2 matching ps's & measure the voltage to be sure it's the same, and use the same guage and length of power cable.
that said, if you use 2 ps's of the same size and type, same length and guage power cable, and be sure you have a solid connection at the amplifier, you will be fine. make sure all fuses are the same size, rating and type, don't use unregulated supplies, turn them on at the same time with the amplifier off.
have used, and set up for others, using this method for many years. have done it with ameritron 4 transistor mobile, dx 1000, 1200, 1600, 1600v, 21 transistor messenger, and a few comp-type amps. be sure you have sufficient current available for what you plan to run before you crank things wide open.

If its not good for the PS...why does Astron put that parallel connection on their power supplies?

Sales pitch ? Hihi

Sales pitch ? Hihi
Both of mine have it don't use. Looks like it supplys a seperate 10a ? Atleast that's what I think it said on the back of my rm40
