What is a Three Phase Online UPS?
A three phase online UPS is an uninterruptible power supply that uses double conversion technology to continuously convert incoming AC power to DC and back to AC, isolating connected equipment from all mains power quality issues including voltage fluctuations, frequency variations, harmonics, and complete power outages.
Key characteristics of three phase online UPS systems:
– Zero transfer time — Equipment is always running from the UPS inverter; there is no switching delay during a power failure
– True double conversion — Complete electrical isolation from mains supply ensures the cleanest possible power output
– Three phase input and output — Suitable for large electrical loads requiring balanced three phase power
– Scalable capacity — Available from 10kVA to several MVA for the largest data centers and industrial installations
– High efficiency — Modern three phase online UPS systems achieve efficiency ratings of 95% to 99% in eco mode

Three Phase UPS Sizing — What Capacity Do You Need?
Selecting the correct three phase UPS capacity requires a detailed load assessment:
– Calculate total connected load in kVA or kW — include all equipment to be protected
– Add 20 to 25% growth margin — allow for future equipment additions
– Determine required battery runtime — how long must the UPS support the load during an outage?
– Confirm input supply — is your facility supplied with three phase 380V/400V as expected by the UPS?
– Consider redundancy — N+1 or parallel redundant UPS configurations for the highest availability
