When it comes to protecting your computer, servers, or other sensitive electronics from power issues, a Line Interactive UPS (Uninterruptible Power Supply) is one of the most effective and popular solutions. But what exactly is a Line Interactive UPS, and why should you consider using one? Let’s break it down in simple terms.
What is a Line Interactive UPS?
A Line Interactive UPS keeps your devices powered during outages and protects them from voltage changes like sags (dips) and surges (spikes). Unlike a basic standby UPS, it actively regulates voltage without switching to battery power every time there’s a minor fluctuation.
How It Works
- Normal Operation: When the power supply is stable, the UPS allows electricity to flow directly to your devices.
- Voltage Regulation: If voltage drops (a "sag") or spikes (a "surge"), the UPS automatically adjusts the voltage using an Automatic Voltage Regulator (AVR)—without switching to battery power.
- Battery Backup: During a power outage, the UPS switches
