Hello I have A Astron RS-70A power supply. The output Volts is currently 13.8Volts. Is there a pot somewhere inside the power supply to adjust the voltage output? I would like to get 15volts out.

Thanks

Check your manual. I have the 50 amp models so the adjustment might be the same. With the top off, near the front top is a small horizontal board, on the underside is a small notched half wheel that will allow you to make the adjustment. I'm not sure how much more voltage you will be able to get out of it.

Ok I will try that.

Thanks

I got home. Unplugged it, took the top off, found the board. I had to discharge the caps and remove the board from the cap. buy removing the two screws. I was able see the thumbwheel and adjust it to get 14.5 volts out. I am happy.

Thanks for the help.

KEWL!! Glad I was able to help.

Let me see.......

Increase of 7/10 of one volt @ 70 amps equals 49 more watts capability
Efficiency of your load, 50%; net difference is 24.5 watts more output.

Getting 25 more watts out of a 100 watt radio, useless!
Running 25 more watts into your previously saturated SS device, senseless.
Man with Golden Screwdriver knowledge, Priceless!

Try not to make unequivocal assumptions as to what he wanted the extra voltage for.

it would be nice if it was that simple,
about the only thing you can say is he would have 49w less power wasted as heat in the pass transistors @70amp,
we dont know the load impedance, current, voltage transformation ratio or the efficiency of the device been used so anything more is speculation.

if you're using such a power supply to run a class-C amplifier, you can just tap the DC straight off the big honkin blue capacitor, which bypasses the voltage regulator completely.
The voltage will be unregulated, meaning it could be up to 18volts under no load, and drop down to maybe 15volts under full load. You could never power a radio from that, but a class C amp would be fine with it. You also wouldn't have any loss from the pass transistors since no current is running thru them.

I found that this Astron runs on the warm to hot to the touch side. I have never seen the cooling fan turn on so I went ahead and jumped out the thermostat so the cooling fan runs all the time. Now the power supply stays cool as cucumber.
