FAQs 6
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?
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. Power supply design: A PSU's design significantly affects its max output rating. The quality of the components, cooling mechanisms and overall build all influence the power the PSU can reliably deliver.
What is a wattage rating on a power supply?
The "W" rating on a power supply indicates its wattage — the higher the number, the more power it can deliver. Some power supplies also have an amperage rating, indicating the maximum current the power supply can provide at a given voltage. You can calculate the max output rating by multiplying the amperage by the voltage.
How many volts can a 24 volt power supply run?
For example, if a 24 V DC power supply’s specifications state that its maximum output voltage range can extend up to 28 V DC, then it must be designed to limit the circuit’s current capacity to 3.57 A (100 VA/28) at that 28 V DC threshold to maintain its Class 2 circuit’s 100 VA power-limitation requirements.
How do I know if a power supply is rated or rated?
Some power supplies also have an amperage rating, indicating the maximum current the power supply can provide at a given voltage. You can calculate the max output rating by multiplying the amperage by the voltage. Rated power output is the continuous output power of the PSU under the rated output and current.
