Power disruptions are a daily reality in Bangladesh, particularly during load shedding seasons when outages can last hours. Whether you’re working from home, running a business, or maintaining security surveillance, an UPS (Uninterruptible Power Supply) has become essential rather than optional. Choosing the right UPS for your computer, router, or CCTV system requires understanding your specific power needs, backup time requirements, and the unique challenges of Bangladesh’s electrical infrastructure.
How to Choose UPS Capacity for Your Devices
Calculating required UPS capacity ensures adequate backup time without overspending. Use this simple approach:
For Computers: Add wattage of CPU (200-400W), monitor (20-50W), and peripherals. Multiply total by 1.25 for safety margin. Example: 400W total × 1.25 = 500W needed, requiring 600VA-650VA UPS.
For Routers & Modems: These devices consume 10-30W total. Mini DC UPS with 5000-10000mAh capacity provides 2-8 hours backup depending on load.
For CCTV Systems: Calculate per camera (5-15W each) plus NVR/DVR (30-50W). Four cameras with NVR = approximately 80-120W, requiring either high-capacity mini DC UPS (20000mAh+) or 650VA traditional UPS.
