Information Technology Equipment (ITE) power supplies play a vital role in powering a wide range of electronic devices and systems. As the backbone of modern electronics, these power supplies are designed to meet strict standards for safety, efficiency, and reliability.

An AC DC power supply is an electronic device that converts alternating current (AC) from a wall outlet or another AC source to direct current (DC), which is the form of electricity needed to power most electronic devices. Since AC power is the standard in homes and industries, but many electronics operate on DC, an AC DC power supply serves as the essential interface to ensure devices receive the correct type of power.

5V and 12V power supplies differ significantly in terms of voltage level, application areas, design requirements, efficiency, safety, and compatibility. Choosing the right power supply depends on specific application needs and device specifications.
