An Online UPS is a type of power backup system that provides continuous, clean, and stable electricity to connected devices by converting incoming power through a double-conversion process.

⚙️ How It Works

An Online UPS uses a double-conversion method:

1. Incoming AC power is converted to DC.
2. That DC power charges the battery and is then converted back to AC.
3. The load (your devices) is always powered from this processed output—not directly from the mains.

👉 This means there is zero transfer time during power outages.
