A power supply unit (PSU) is an essential component that converts electrical power from a source into the correct voltage, current, and frequency required by various devices. Unlike the alternating current (AC) supplied by power companies, PSUs convert this power into direct current (DC), suitable for electronics that demand stable and specific voltage levels.
PSUs are integral to both household and industrial settings, powering devices ranging from personal computers, where they supply energy to critical components like the motherboard and graphics board, to programmable logic controllers (PLCs) in manufacturing processes.
The functionality of a PSU is divided into four critical sections:
Diverse applications necessitate different types of PSUs, including:
Selecting the right PSU is crucial for ensuring the optimal performance, efficiency, and reliability of your devices.
*Including some distributors, etc.
