What defines a power-limited power supply and how is it different from
a non-power-limited power supply?



Answer :

A power-limited power supply is one that has a maximum power output it can deliver. This limit is set to protect the connected devices from receiving too much power and getting damaged. When the connected devices draw more power than the power supply can safely provide, the power-limited feature kicks in to prevent potential harm.

On the other hand, a non-power-limited power supply does not have this restriction on the amount of power it can deliver. It can continuously provide power as long as it is within its operating limits without an automatic shut-off mechanism due to power limitations.

Differences between a power-limited and non-power-limited power supply:
1. Protection Mechanism: A power-limited power supply has a protection mechanism that limits the amount of power it can deliver to prevent overloading and damage to connected devices. In contrast, a non-power-limited power supply does not have this protective feature.

2. Usage: Power-limited power supplies are commonly used in devices where power regulation and protection are crucial, such as in medical equipment or electronic devices that require precise power control. Non-power-limited power supplies are often used in applications where constant and unlimited power supply is needed, like in some industrial equipment.

3. Safety: Power-limited power supplies enhance safety by preventing excessive power flow that could lead to overheating or damage. Non-power-limited power supplies, while not having this automatic protection, are designed to operate within safe limits under normal conditions.

In summary, the key distinction between a power-limited power supply and a non-power-limited power supply lies in the presence or absence of a built-in power restriction mechanism that safeguards connected devices from receiving too much power.
