What happens if a power supply exceeds a maximum output rating?Overload protection: Surpassing a power supply's maximum output rating can lead to overheating, voltage fluctuations and even complete power supply failure. Understanding maximum output ratings ensures you only support loads the power supply can handle and prevents damage to the power supply and connected devices.
What does max output rating mean on a power supply?Increased efficiency: Operating a power supply close to its max output rating can limit its efficiency and shorten its useful life. When you understand the max output rating, you can operate between the actual power draw and maximum output for optimal performance and power supply life span. What Do Ratings Mean on Power Supplies?.
Can I use a 400 mA power adapter on a 500 mA power supply?Yes, as the others say – using a 400mA device on a 500mA power supply is OK. Even a power supply that was rated for 2000mA or 2 Amps or more would work. Using the wrong voltage is often not OK. Which is better a 16 V or 12 V power adapter? The answer depends completely on the amp’s circuitry.
Can a 500mA power supply draw 300mA?If a camera draws 300ma on a 500ma supply, it will draw exactly the same 300ma from a 1a supply, or a 2a supply. A power supply that can provide more amperage will just have extra unused spare capacity compared to a equal one with a lower amperage. Can you plug in a 12V 500mA adapter?.
What factors affect a power supply's maximum output rating?Depending on your needs and application, several factors can affect a power supply's maximum output rating.
