What is a True Online UPS?
A True Online UPS, also known as a Double Conversion UPS, is an advanced backup power system that ensures your devices get clean and stable electricity at all times. It works differently from basic UPS systems:
- Double Conversion: Converts AC power from the wall into DC to charge its battery and then back into AC to power your devices. This ensures consistent and clean electricity, free from fluctuations like surges or drops.
- No Power Interruption: Unlike standard UPS systems, which take a few milliseconds to switch to battery power during an outage, a True Online UPS has zero transfer time. It’s always running through its inverter, ensuring continuous power.
- Pure Sinewave Output: The power it delivers is smooth and stable, which is ideal for sensitive electronics.
What is a Regular UPS (UPS Battery)?
A regular UPS, or what most people call a "UPS battery," is a simpler device that provides power backup during outages. However, it has its limitations:
- It switches to battery mode with a slight delay (~2-10 milliseconds).
- It might not handle power surges or fluctuations as effectively.
- Often produces a less stable "modified sinewave" output, which may not be ideal for advanced or sensitive equipment.
What Makes a True Online UPS Better?
| Feature | Regular UPS (UPS Battery) | True Online UPS |
|---|---|---|
| Power Delivery | Slight delay (2-10 ms) | Instant, no delay (0 ms) |
| Power Output | Modified sinewave | Pure sinewave |
| Voltage Stability | Limited | Highly stable (±1%) |
| Best For | Basic devices like PCs | Critical systems, servers |
| Cost | Lower | Higher |
Who Should Use a True Online UPS?
A True Online UPS is designed for mission-critical applications where power interruptions are not acceptable. Here are the most common scenarios:
1.Businesses with Critical Systems:
