Description
What Is the DAXIN 3H3 120kVA 3/3 Phase Online UPS?
The DAXIN 3H3 120kVA is a 120kVA/96kW low-frequency online UPS designed for high-capacity critical applications requiring three-phase input and three-phase output power protection.
Its 3/3 phase architecture is intended for facilities where both the incoming electrical supply and protected critical loads operate on three-phase power.
The reference configuration supports 380/400/415VAC three-phase input and output, 0ms mains-to-battery transfer and greater than 90% efficiency.
Battery configuration, bypass, communications, redundancy requirements and other project parameters should be confirmed according to the connected load, required backup time and approved DAXIN technical proposal.
Key Benefits
- 120kVA / 96kW Capacity: Designed for high-capacity critical three-phase loads in industrial and infrastructure applications.
- 3/3 Phase Architecture: Three-phase input and three-phase output support large three-phase electrical systems.
- Low-Frequency UPS Design: Intended for demanding industrial and infrastructure critical-power applications.
- Online Power Protection: Provides continuous conditioned power for sensitive and mission-critical loads.
- 0ms Mains-to-Battery Transfer: Maintains output during utility-to-battery transition according to the reference specification.
- Configurable Battery System: Battery configuration and runtime can be engineered according to load and backup-time requirements.
- Monitoring and Protection: Display, alarm, protection and communication functions support system operation and maintenance.
- Project-Based Configuration: Parallel, redundancy, bypass and communication capabilities must be confirmed for the selected configuration.
What Does 3/3 Phase Mean in a UPS?
A 3/3 phase UPS uses three-phase AC power at the input and supplies three-phase AC power at the output.
This architecture is commonly used for high-capacity critical loads in data centers, industrial facilities, power infrastructure, healthcare systems and transportation applications.
The DAXIN 3H3 120kVA uses this three-phase input and three-phase output configuration for large critical-power applications.

How to Select a 120kVA Three-Phase UPS
Select the UPS according to the actual connected load in kW and kVA, input and output voltage, power factor, required backup time, battery configuration, bypass requirements, redundancy architecture, communication interfaces and installation environment.
For a 3/3 phase UPS, confirm that both the site electrical supply and protected critical loads require three-phase power.
Provide DAXIN ENERGY with the load list, single-line diagram, site voltage, required runtime, redundancy requirements, communications and installation conditions for project configuration.
