UPS vs UPS with Surge Protection: Which One Should You Choose?

This article explains the difference between a standard UPS and a UPS with surge protection, helping users understand their roles in power continuity and surge suppression. While a UPS guarantees backup power during outages, built-in surge protection is often limited. For complete safety—especially against lightning and high-energy transients—external SPDs are essential. The guide explores technical comparisons, IEC-standard parameters, and best practices for integrating Type 1, Type 2, and Type 3 SPDs with UPS systems, ensuring reliable protection for IT, industrial, and medical applications.
