how do you power it all??

[Digger]

You might want to check out Altronix line. They could have something you like. They are also made in the USA (with parts from China I am sure).

Does it offer multiple outputs like the pd9?

regards

Just one big fat output.

You can then split and fuse as necessary.

50 amp capable? Do you weld with that thing also?

 

[Skibum]

I think it is 35 amps continuous and 45 peak.

Yes, It'll weld, and cook burgers... lol

Paul,
How much amp can each outlet of your Altronix outputs? Most of my stuffs require at least 1 amp (Cable modem, Switch, Router). And the ELK unit can only output 250ma.

Elk also has a ELK-PD9HC that outputs 400mA per output and multiple outputs can be combined for even higher output.

So what would I need for something that requires the following. Altronix should do. Any explanation to help figure this stuff out would be good.

12V, 7.0A Power Adapter

Altronix, Preferred Power, Napco, Elk (maybe) all have high current supplies with battery backup. They are not cheap though. Then you would use a distribution board (or boards) with fuses or PTC's on each line if you want.

7 A is a lot of current. What are you powering if you dont mind me asking?

 

[noshali]

I am thinking about getting the storage central from netgear. Don't have it yet...maby it does not have a adapter and uses something like a notebook adapter.

As usual I am lost. I just bought a HD book external USB drive. This is what the power supply says.

Ac Input 100-240 VAC 0.65A Max 47-63 HZ

DC output 12VDC 2A

I can bet my life it is not 2 amps as that is a lot of power. So what wattage do I need. Will it work with a elk pd9?

regards,

 

[WayneW]

If it says it can output 2 amps, I would tend to believe it. 12v X 2A = 24watts available. I just grabbed a random old small IDE drive off the shelf and it looks like it draws about 6 watts. If you know what hard drive is in your unit, you can go to the manufacturers web site and get the power specs for the drive. Then add a little bit for the assumed USB-IDE converter. The pd9 can certainly power this, but it may take multiple outputs ganged together to give the required power.

 

[noshali]

Thanks. That makes sense. So the rule of thumb for such conversion is voltage time amps.

So a 15amp load at 120volts whould be able to carry a load of approx 1800 watts?

It isn't just a rule of thumb, its THE LAW! Named after Mr Ohm, it is part of Ohm's Law.

W = V x A

But, this is only true for simple DC and/or resistive loads, such as incadenscent light bulbs. It gets a lot trickier with things like computer power supplies, which are also known as switching power supplies. These do not represent a uniform load so that have a thing called the "power factor" that breaks this rule. That is why computer UPS (battery backups) advertise 600 VA instead of 600W. they usually say 600 VA / 480W or something like that, with the VA number appropriate for sizing computers and the W number appropriate for incandescent lighting.

I converted the hard drive I looked at to Watts because the raw drive needed both 5V and 12V, while your supply was only 12V. Your USB enclosure would handle the USB-IDE conversion and the 12V-to-5V conversion
