im looking at buying this power supply, but im not sure how many things i can run on it

You can run 32amps worth of things on it. Depending on the current rating of your things, It might be 1 or could be 32. I personally would go above 25 amps worth of things on this supply.

It gets mixed reviews on Eham and can be had for about $120 on Amazon with no tax and free shipping.

You are thinking backwards.

Decide how many of what THINGS you want to run, THEN pick the supply.

(You are not in government purchasing, are you?):lol::lol::lol:

sorry im kinda new to radio's, what would be a nice way to hook up radios in my room with out have a whole bunch of tiny little converter boxes???

What radios?

A good rule of thumb is to put as much time and thought into your question as you hope someone will put into the answer.

 

[jeep_in_deep]

right now im just playing with cb's and scanners, but im wondering how, if there is a way to set it all up to one power supply?

 

[petey_racer]

For that kind of money I'd stay away from that Pyramid stuff.
I'd go this route: http://www.universal-radio.com/catalog/hamps/4082.html

Yes, there is.

You supply should provide about 120% of the total power needed by all the equipment you intend to run at the same time.

Your CB probably needs 2A.

I think at this point jeep_in_deep is now asking about power distribution - see below:

You can actually spend about as much or more on power distribution as in the actual power supply
depending on your personal preferences.

For the shack I prefer the West Mountain RIGrunner solutions:

There is also the powerwerx less costly solutions:
CAUTION: You must individually fuse each leg connected to these since there is
no provisions for fuses within these device's.

Then there are the MFJ product line below but beware of the poor workmanship
and I have provided eham review links to back up that tidbit of info.

Then there is this LDG Electronics panel but it is only for very low current devices.

Why are you always such a d!*k?? Do you get off on being such an a$$h0!e?



To answer the OP's questions, you can run all of you 12v equipment off of a power supply that is capable of handling your total load plus 20%

I already answered his question without taking the tread off topic just to bash another person.:wink:

To answer your second questions, maybe you need a mirror!:roll:

By the way, did you read my previous response in this thread prior to the one you chose to criticize??

 

[prcguy]

Where does that formula come from? It totally depends on the power supply, some cheap supplies will burn up operating continuously at half their rating and some will go forever at over 100% of their rating. I have a feeling you would not want to run the Pyramid supply at more than 50% of its rating continuously based on some owner feedback I read. It can probably run a bunch of scanners and transceivers on receive with occasional transmitting but don't load to anywhere near its "rated" current if you want it or your radios to survive long.

[N_Jay]

Rules of thumb are nothing more then rules of thumb.

You have to assume the ratings are accurate.

Would you design a system to which has ZERO margin, either for errors or expansion?

Well for PS systems the RULE OF THUMB is 50% to 100% margin.
For hobby systems you are probably safe at 20%.
Business systems fall in between.

Maybe I overreacted and should have just kicked the dog for me being in a cranky mood when I came on here..... sorry....

In most cases you shouldn't load something past 80% of its rating. There should always be a buffer.

Maybe.

What is the margin you use?

NEC is 80% full for a breaker box, and 80% load on a circuit.

Add up all your amp requirements from the devices you plan on putting on the treadmill....

Don't forget the surge.. :lol:

I run two 65 watt ham radios, one 5 watt HT, and a 4 watt CB on an 18 amp Astron PS. Which one you get all depends on how many radios you are planning on talking on at the same time. If you are like me, and can only talk on one radio at a time, then make sure you get a power supply capable of handling what that radio will put out, and then add a few amps for your other radios. In receive mode, these radios use very little amperage. This 32 amp ps you are thinking about buying would be like putting a 460 cubic inch engine in a Ford Escort. LOL!

Your 18amps is barely enough to power one 65watt radio at full transmit power. All 4 items and your at your rated supply. Better to have to big a supply than to small.
