| I know this is an old post but it's a simple question with a simple answer so it should be unneccessary to leave it unanswered.
Wether the secret device is an amplifier or a dc/ac converter doesn't matter, they behave in the same way. They only draw what you command them to, up to a maximum of 70 Amps. Granted, they also draw a base current, something like an Amp or two at most. So unless you turn the volume to full, or hook up a microwave to the dc/ac converter or whatever, you should be fine on your 20 Amp fused circuit. Like torbjorn says: you can draw up to 240 Watts of power. |

| Ok.........curve ball..........Isn't the keyword here "draw"....?
Doesn't a device hooked to any proper voltage source, only draw what [ current ] it needs to operate at peak efficiency ? hooking up a source that is overvoltage would be the reason something would fry...? Or do I need to go back to my textbooks ? |

| Well, what for kind of a device is it? What determines its current consumption? Now, when it draws 70 A at 12 V, this means a power consumption of 840 W, can the device fulfill its duty when it is not allowed to consume more than 240 W ? | |

|
| I have some electronics knowledge, but not dealing with large amounts of current.
I have a device I want to put into a car that runs on the battery (12V 70ish amps) But i olny want to give the device 20 amps at 12V So what do i need to reduce the amps from 70 to 20? Thanks in advance. -RonX |
