Typical alternators were 50-70A at 12V, or about 720W (roughly 1HP.) Bigger ones are more common now as power demand for electronics and other vehicle systems increases. A quick look yields 90-120A for cars, and 200A or more for trucks …
Web28 de jun. de 2016 · They also use very small <75A max alternators to reduce size, weight and cost. Heavy duty police, contractor & RV grade vehicles, with very high 12V loads, take the opposite approach using oversized >150A alternators and ECU that increase engine idle speed up to a "high idle" to provide >70% of their rated output at idle when needed. Web25 de set. de 2024 · The voltage regulation of an alternator or synchronous generator is defined as the rise in the terminal voltage when the load is decreased from full-load rated value to zero. The speed and field current of the alternator remain constant. In other words, the voltage regulation of the alternator can be defined as the change in terminal voltage …
