Typical Output Voltages for Industrial Power Supplies

2024.07.26
Industrial power supplies are critical components in a wide range of applications, from manufacturing and automation to telecommunications and medical equipment. Understanding the typical output voltages for these power supplies is essential for selecting the right equipment for your specific needs. This article explores the common output voltages for industrial power supplies and their applications.
 

Common Output Voltages


Industrial power supplies typically offer a variety of output voltages to accommodate different devices and systems. The most common output voltages include:
5V DC: Widely used in low-power applications such as sensors, microcontrollers, and communication devices. The 5V output is essential for many digital circuits and is a standard voltage for USB-powered devices.
12V DC: Commonly used in automotive applications, security systems, and LED lighting. The 12V output is versatile and supports a wide range of industrial and consumer electronics.
24V DC: The standard voltage for industrial automation and control systems. It is used in programmable logic controllers (PLCs), relays, and various industrial sensors. The 24V output is preferred for its balance between power efficiency and safety.
48V DC: Often used in telecommunications and network equipment. The 48V output is ideal for powering servers, switches, and other high-power devices in data centers and communication hubs.
120V AC and 240V AC: These are standard alternating current (AC) output voltages for industrial power supplies that need to provide power to equipment designed for direct connection to the electrical grid. They are used in heavy machinery, HVAC systems, and large-scale industrial equipment.
