camera power

[ZK 0]

The cameras I'm trying to install are rated 4.5 watts at 24VAC. They also will run on DC but the Watts @ 12VDC are not listed. My power panel is an Altronix ALTV615DC416UL. I was hoping to hook all the cameras up to it but am unsure as to what the camera current pull will be at 12VDC.

 

How do I figure how much amperage a camera takes at 12VDC when all I have is 4.5 Watts rating at 24VAC?

 

Thanks

Post the actual camera specifications, or post a link where we can review it. I would be more concerned on knowing what cameras these are exactly (IR, etc). That is a good power supply unit by the way, very stable.

4.0 watts is the specification using 12VDC. Figure roughly .330A current.

no problem, you should have a nice looking system using those components.

What size fuses should I use? The Altronix comes with 3.5 amp fuses on each output. So if the cameras only need .330 amps, should I use a .500 amp fast blow fuse?

i've never had to change the fuses with 330ma cameras on altronix power supplies.

Keep in mind that you'll need to run some voltage drop calculations based on an allowable -10% voltage drop and the 12VDC source. -10% of 12VDC is a good deal less than -10% of 24VAC !

 

Here is a link to the Altronix Voltage Drop Chart; here is the VD calc by Panasonic
