What is the devices to prevent overload?
The main device is the circuit-breaker, which is set to trip and cut off the supply if the current exceeds a preset amount. On low-power supplies up to about 100 amps thermal fuses can also be used, a piece of thin wire enclosed in a fireproof container. When the current exceeds the rated amount, the wire melts and this cuts of the supply. Obviously fuses are not as accurate as circuit breakers but they are cheaper.
How does an Uninterruptible Power Supply protect computer equipment against electrical power brownouts and blackouts?
Since you are constantly running from the enclosed battery (which is always being charged when plugged in) your computer is never exposed to power fluctuations coming from electrical source.
How do you replace a computer fuse?
The only fuse located in a computer is the one in the power supply. It can be very dangerous to open a power supply without proper training. If you do not have the requisite training to repair a power supply, please do not attempt to open it. Your life isn't worth losing over a $50 hunk of metal and wires.
What are the components of a power supply?
Sometimes when people buy a computer power supply unit (PSU), there are several components in the box: a AC power cable to connect the power supply to the wall mains outlet, the power supply itself (PSU) that converts mains power into more useful forms of power, and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer. (On a modular power supply unit, those cables can be detached from the PSU). A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component. Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.

What is the power of a power supply?
power supply is a device that supplies electric power to electrical load
Regulated power supply?
all about regulated power supply
What are advantages of power supply?
Advantage of regulated power supply.
What power supply should you replace a 175 watt power supply with?
any power supply with at least 175 watts
What are the components of an electromagnet?
Coil and core, and you'll need a power supply to activate it.
What is an ac adapter for a phone?
An AC Adapters are a type of external power supply which is often enclosed in a case. AC Adapters are used within electrical devices that require power but do not contain internal components to derive the required voltage and power from the mains.
What are the applications of variable DC power supply?
variable dc supply are used to get desired amount of dc supply
