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 is a power supply max power rating?
The components it can power depend on its maximum rating, typically measured in watts. It indicates how much energy a PSU can deliver to its connected parts. Power supply max power ratings determine the amount of energy the power supply can safely deliver to the connected devices, making them essential for several reasons.
What if a 12V 5A power supply is not regulated?
There are chances that if you select a 12 V 5A unregulated power supply, it will give some 20V DC open circuit (no load / very low load) voltage. If a low current consuming circuit is connected, it may see some 18-20 V DC. If the components in the circuit (which is rated at 12V) have 16V rating may malfunction or fail in long run.
What does amps mean on a power supply?
In a nutshell, the Amps rating on a power supply, charger or adapter explains the maximum amount of current that it can safely provide in an hour. Any amperage of charger rated above what's required for your device is safe to use with your device, providing the PSU voltage is the same as the input voltage or within a tolerance of 1 volt.
What does a power supply rating mean?
it indicate the maximum current the product will draws from it's power supply. Usually the current drawn is lesser. of the product. The specification will tell us that it will not draw more current beyond what is indicated. power supply rating of 12V 2A, with 1A safety margin.
What if one power supply is heavier than the other?
A tip: if one power supply is heavier than the other, it is probably the 550mA supply. mA is how much current the device is drawing from the PSU. The first power supply is capable of supplying enough current for a 250*15=3750milliwatt load and the second one for a 550*15=8250milliwatt load (for devices rated at 15v).
