This article clarifies the differences between a UPS (Uninterruptible Power Supply) and an Inverter, explaining their functionalities and applications.

Introduction

UPS stands for Uninterruptible Power Supply. It’s a device that provides emergency power to a load when the main power source fails. The switching time is incredibly fast, ensuring continuous power to sensitive hardware like computers and telecom equipment.

UPS vs Inverter

A power inverter, on the other hand, converts DC (Direct Current) to AC (Alternating Current). When AC power is available, the inverter charges the battery from the mains. When the AC power is unavailable, the inverter supplies power to connected equipment from the battery.

Key Specifications: UPS vs. Inverter

Here’s a table summarizing the key differences between UPS and Inverter:
