3Phase / 3Phase UPS

3 phase online ups

3Phase / 3Phase UPS (10kVA to 120KVA)

Input and Output: Both input and output are three-phase, meaning they involve three alternating currents (AC) that are out of phase with each other by 120 degrees. This configuration is typical for applications requiring higher power capacity and stability.

Available in capacities ranging from 10 kVA to 200 kVA. The specific capacity determines how much power the UPS can supply to connected equipment during a power outage.

Double-Conversion Online: This is the most common topology for high-end UPS systems. It continuously converts incoming AC power to DC and then back to AC power, ensuring a clean and stable output to connected devices.
