⚡ Online UPS Systems: Pure Power, Always
Scalable, Reliable, and Smart Power Protection.
Power disruptions can cost you data, time, and revenue. Siri Technofabs offers a comprehensive range of Online UPS and Line-Interactive UPS systems (1kVA to 40kVA) designed for homes, data centers, and critical industrial applications. Experience zero transfer time and pure sine wave performance.
Why Choose Online UPS?
Online UPS provides the highest level of protection by completely isolating your equipment from raw mains power.
Continuous Power
Uses a "double conversion" method (AC-DC / DC-AC). The load is always powered by the inverter, ensuring zero transfer time during power failures.
Pure Protection
Delivers a fixed, stable output free from voltage fluctuations, spikes, and frequency distortion. Ideal for sensitive electronics like servers and medical equipment.
Scalability
Designed for uptime and data integrity. Our Online UPS tech is scalable from small office setups to massive industrial requirements (up to 1000kVA).
Wide Range
From 1kVA High Frequency units for IT loads to robust Galvanic Isolation UPS for manufacturing, we cover every industrial need.
Online vs. Offline UPS: Key Differences
Understand which system is right for your application based on operation, distortion, and cost:
| Feature | Online UPS (Double Conversion) | Offline UPS (Standby) |
|---|---|---|
| Operation | Battery powers load via inverter continuously. | Mains power load directly; switches to battery on failure. |
| Transfer Time | Zero (0 ms) - Seamless switch. | Visible delay (milliseconds) during switch. |
| Voltage Distortion | Eliminates all distortion; pure output. | Passes mains fluctuations to load. |
| Output Waveform | Pure Sine Wave (Fixed & Stable). | Square / Pseudo Sine Wave (On battery). |
| Cost | Higher (Precision components). | Cheaper (Basic backup). |
| Best Use Case | Servers, Medical, Industrial, Critical IT. | Home PCs, Routers, Basic Electronics. |
