Power Supplies

Power supply units: The key component for supplying power to electronic devices

A power supply is used to supply electricity and typically consists of an input side, which is connected to the power source, and an output side, which supplies the converted energy to the device to be powered. The conversion is usually from alternating current (AC) to direct current (DC), as most electronic devices require direct current to function.

Types and specifications

Power supplies are available in a variety of designs, from compact models for smaller devices to powerful units for servers and data centers. There are internal and external power supplies, depending on the type of device and application.

Power and efficiency of power supply units

Another important criterion for power supply units is efficiency. High-quality power supply units have a high efficiency class, which ensures that the majority of the energy is used and losses due to heat dissipation are minimized. This is particularly relevant in large IT infrastructures in order to save energy and extend the service life of the hardware.

Efficient protection mechanisms

Modern power supply units also offer protective functions such as overvoltage, overheating and short-circuit protection to protect both the power supply unit and the connected devices from damage. These functions contribute to a safe and stable power supply.
