Key factors for choosing a UPS – Recommended / Best-sellers
A concise technical checklist to select a UPS for critical tasks—prioritizing safety, continuity, and lifetime value.
Capacity (VA/W) & backup time
Assess actual load, add 20–30% headroom, and set backup time sufficient for safe save-and-shutdown procedures.
UPS architecture
Choose Offline / Line-Interactive / Online (Double-Conversion) based on sensitivity; sine-wave output is recommended for critical loads.
Ports & deployment
Specify outlet count (IEC/Universal), data-line protection, and Tower/Rack mounting to fit the space.
Voltage protection & power quality
Support for AVR/Surge Protection to mitigate sags/surges and maintain stable power.
Batteries & lifetime cost
Consider type/capacity/service life, hot-swap replacement, and total cost of ownership (TCO).
Management, software & services
USB/Network ports for auto-shutdown, monitoring/logging software, and clear warranty terms.
Tip Choose a model that supports the actual load of computers/servers/POS/CCTV and set backup time to match your shutdown process.
3 basic tips for choosing a UPS
2) Protection features
Select UPS with AVR for under/over-voltage and surge protection. For critical tasks, use Online UPS for higher stability.
3) Connectivity & popular picks
Ensure enough outlets. Prefer USB/Network support for auto-shutdown, and choose field-proven models.

FAQ
Frequently Asked Questions about UPS
Answers about sizing VA/Watt, UPS types, runtime, and warranties—so you can decide faster and more accurately.
What VA/Watt rating do I need for my devices?
Add up the total power of all devices and keep 20–30% headroom. Then choose a VA/Watt rating equal to or higher than that for stable operation and future expansion.
How is Line-Interactive different from Online UPS?
Line-Interactive units use AVR to regulate voltage—good for general use. Online UPS continuously converts power for very stable output—best for servers and critical systems.
How can I get longer backup time (runtime)?
Check the model’s runtime specs. To extend runtime, reduce connected load or choose models with higher-capacity batteries / external battery options.
What about warranty and after-sales service?
Genuine products include official warranty. Our team can help with checks, claims, firmware updates, installation/config advice, and full tax invoices.
