Tehran UPS Uninterruptible Power Supply Capacity Calculation A Practical Guide

Why Proper UPS Sizing Matters in Tehran?

In a city like Tehran where power fluctuations and unplanned outages occur frequently, calculating UPS capacity correctly becomes critical for businesses. Whether you're protecting sensitive medical equipment or ensuring continuous operations in a data center, undersized systems risk equipment damage while oversized units waste energy and budget.

Key Factors Affecting UPS Capacity

• Total connected load (in watts or VA)
• Required battery backup time
• Voltage requirements (single/three-phase)
• Future expansion plans
• Local power quality issues

Step-by-Step Calculation Method

1. Load Assessment

Create an equipment inventory table:

Device	Power (W)	Runtime Needed
Server Rack	3000	30 mins
Security System	500	4 hours

2. Battery Sizing Formula

Use this industry-standard equation:

 (Battery Capacity) = (Total Load × Backup Time) / (Battery Voltage × Efficiency) 

Real-world example: For a 5kW load needing 2-hour backup:

• 5000W × 2h = 10,000Wh
• 48V system with 90% efficiency
• 10,000 / (48 × 0.9) ≈ 232Ah

Common Mistakes to Avoid

• Ignoring power factor (VA vs Watts)
• Forgetting temperature impacts on batteries
• Overlooking harmonic distortions
