Maximizing Reliability:
Power Supplies for Industrial Switches

What is an industrial switch?

An industrial switch is a networking device used to connect multiple devices, such as computers, sensors, and controllers, within a Local Area Network (LAN). It is designed to handle the demands of industrial environments such as extreme temperatures, humidity, dust, vibrations, and electromagnetic interference (EMI). Unlike standard commercial network switches, industrial switches are built to offer higher durability, reliability, and operational safety.

Features of an industrial switch

Industrial switches are generally constructed with metal enclosures for physical protection. Reliability is prioritized with features like redundant power supplies and network protocols. Enhanced security measures safeguard against unauthorized access and cyber threats. Additionally, industrial switches are well-equipped to handle electrical noise and surges through superior shielding and protection, ensuring reliable communication. Finally, certifications for industrial standards, like IP ratings for dust and water resistance or ATEX for explosive environments, guarantee their suitability for specific applications.

Selecting power supplies for your industrial switch

By selecting the correct power supplies, industrial switch applications can benefit from both efficiency improvements and reliability enhancements. 

As an example, the following three MicroPower Direct products —the MLSR120K, MPB3048RWS16, and MPM-90SVLD— can be integrated into industrial switch applications
