I've got an AC/DC Adapter that plugs into the wall that puts out 12v 3A and connects to a small DVR box. Well I wanted to know how much DC current the DVR box actually draws so I hooked up a multimeter on the DC side and the device was pulling about 1.5amps. I also have one of those "Kill A Watt EZ" meters that you plug into your wall and then plug your device into it and it will tell you how much current, voltage, watts etc that your device is pulling. When I used this device it gave me a 0.34amp reading while I was still getting 1.5amps from my multimeter.
So my question is, is there a way to convert the AC amps into DC amps so that way if I wanted to test another device, I could simply plug that device into the Kill A Watt EZ and then convert the amp value into the DC amp value, rather than having to measure on the DC side using a multimeter.
Here are the numbers I was getting...
Multimeter on the DC side
1.5amps
Kill A Watt EZ on the AC side
0.34amps
122.5v
20.5watts
0.49pf
Thanks in advance!
