Hot Rods Universal voltage drop 12v 6v

Hello , has anyone here ever seen a voltage drop like this and if so how does it work ? thanx Chance

 

Could be a couple of resistors, could be an integrated circuit. Have to open it up to tell.

 

It looks like it might be ceramic, and have a couple resistors inside?

according to this description, that's what it is. You only get the 6v dop if you have a load that draws 6 amps.

 

The brand name on that unit was Vol.Ta.drop we used to carry them . They were very low amperage, would work for maybe 1 or 2 gauges not much more.
They did have resistors inside like Squirrel said.

now we know what it's a chinese copy of....

thanks

 

a little more googling....

 

Resistors are HORRIBLE for reducing voltage with any consistency, if the load they feed doesn't draw exactly the same current all the time. Sometimes you don't need any precision, sometimes you really do.

 

Works OK for heaters, not so well for sensitive electronics

So is it for use in a 6 volt car to run a 12 volt radio or fog light or ? and what bolts to what ?

 

The other way around, it reduces voltage from 12V to about 6V, if you draw the right amount of current from it. The 2, 3 and 4A outputs should allow you to use it for something that needs 12, 18 or 24 watts. You will lose the same amount of power as heat in the reducer, so if you don't have electrical power to spare there's another reason why resistors aren't the best option.

Increasing voltage is a much harder operation than reducing it. Generally expensive until relatively recently (chinese electronics).
