Do you guys think that a GZV-4000 40amp power supply is enough amps to operate a RM-Italy KL-503 amplifier? This GZV-4000 is supposed to be a great power supply for operating two way radio "no hash & scratch etc." Thanks for your input guys...Jeff

40 amp supply to run KL-503?

Hmmmm . . .
I have one of these Diamond PS. Starting to make noise on certain freq's. Owned it over 2 yrs now. Have you thought about getting a Tripp-Lite PS? They are a transformer-type supply and not a switching-type supply like the Diamond and not prone to noise. True; the Diamond supply is cheaper. However, how cheap is it if you end up buying a transformer-type supply after you buy the Diamond and it starts making hash?

So true I am still in the middle of doing this if you can believe. I thought that this supply was upgrading to a good one.
There are a lot of considerations when you look for a power supply. The biggies are the voltage and the amount of current it can supply continuously. That means you have to know those things first, how much is needed, and that's not so simple sometimes.
One way of determining how much current is required is by adding up the sizes of the fuses to each device to be connected to that supply. Those devices may not draw that current all the time, but they -can-. Then you get to find out about how power supplis are rated! There are two common ratings, ICS, and CCS. Those are intermittent current supply, and continuous current supply. Or, surges, and all the time. The one to pay attention to is that 'all the time', or CCS rating. That is not what you commonly see in the advertising, that's usually the ICS, or surge rating. Continuous current is also a way of saying 100% of the time, if that helps. Not quite as simple as you thought, huh? Oh well.
It's aslo nice to get a bit 'more' than you think you'll need. The bigger that 'fudge factor' the better off you'll be.
Another thing to keep in mind is that the output power of a device is a terrible way of trying to figure how much input power is required fo the thing to work. That gets into the efficiency of that device, and nothing is ever 100% efficient! You'll be lucky to get 50% efficiency.
Have fun.
