# Quick Answer: How Many Volts Does A 200 Amp Alternator Put Out?

## What is the minimum RPM of a 12v car alternator?

The minimum RPM is highly dependent on the specification of alternator.

But a basic alternator will produce charging current anything above 2000 rpm.

We can safely say, an economy car will idle around 750 rpm, a sports car around 1250 rpm and a race car around 2000 rpm..

## How much power does a car alternator put out?

But nowadays, a single alternator can produce power up to 2500 Watt, depending on the power demand. The power that can be produced by an alternator is determined by the alternator rating. The output of the alternator ranges from 40 Amp up to 120 Amp. For high-amp alternator, it can generate up to 300 Amp.

## Is 200 amp alternator enough?

But, with a 200 amp alt you should be able to supply enough power for most systems.

## How many amps does an alternator put out at idle?

50 ampsAt idle speeds of about 650 RPM it can only produce 50 amps or so. This is why when you have a loose alternator belt or a defective belt tensioner, you only hear the squeal when you hit the gas initially after you start the engine, not with the engine idling.

## How much voltage does a alternator produce?

Normal Output An alternator should put out between 13.5 and 15 volts of power. The alternator should be tested with the engine idling and electrical accessories, such as the radio and headlights, turned off.

## How much power does it take to produce 100 amps from an alternator?

about 4 HPAn alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output.
