Distributed Power Supply Recommendation

[jdog 0]

I'm looking for an 8 camera 12VDC 5 amp distributed power supply that is not mounted in an enclosure. I already have two structured media enclosures where all my siamese coax is routed. I want to locate the power supply in an enclosure and convert to two CAT5 cables w/baluns that run to my computer/dvr location. Looked at Altronix and didn't find anything.

Altronix will have it if anyone has it ... but most likely you will have to buy the power supply itself then build the rest from other parts such as buying radio shack barrier strips or terminal blocks.

If you want 24VAC to 12VDC distributed power, I think you can get those without an enclosure, but if you want line voltage to 12VDC distributed power, I think it will likely include an enclosure.

 

Best,

Altronix makes all of the parts for AC and DC power supplies.

 

For the voltage converter/regulator part, you can use the SMP7; which will convert 28VAC to 24VDC or 12VDC @ 6A (http://www.altronix.com/index.php?pid=2&model_num=SMP7).

 

You would also need a power transformer. Look at the Altronix T2428175 for in-enclosure (open transformer) mounting or the T24175WP or T2428175WP for transformers in enclosures (http://www.altronix.com/index.php?pid=2&category=17).

 

You may also need a fuse block (Power Distribution Module). The PD8 has 8 fuses (http://www.altronix.com/index.php?pid=2&category=13).

 

They even have the nylon spacers and other accessories (http://www.altronix.com/index.php?pid=2&category=20).

Thanks to those who replied. Based on the piece parts cost, it looks it will be cheaper to purchase a power supply in an enclosure and remove the contents and place them in my structured media enclosures.

The biggest potential problems with installing the parts into your existing enclosures would be the proximity of the power transformer to cables and other devices and the potential shock hazard from open 110VAC connections. Transformers throw out a lot of EMF that can leak into audio, video and other circuits. The higher the voltage, the more likely it is to cause interference. That's why I might recommend locating the transformer outside and running the lower voltage into the enclosure.
