Description
What Is the DAXIN 3H3 80kVA 3/3 Phase Online UPS?
The DAXIN 3H3 80kVA is an 80kVA/64kW low-frequency online UPS designed for 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
- 80kVA / 64kW 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 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 configuration is commonly used for medium- and high-capacity critical loads in data centers, industrial facilities, telecom infrastructure, healthcare systems and other facilities operating three-phase electrical equipment.
The DAXIN 3H3 80kVA uses this three-phase input and three-phase output architecture for critical-power applications requiring 80kVA-class UPS capacity.
What Loads Can an 80kVA UPS Support?
The DAXIN 3H3 80kVA reference model is rated at 80kVA / 64kW. The actual equipment that can be supported depends on the combined active power, power factor, startup or peak demand and required operating margin of the connected loads.
UPS sizing should be based on measured or calculated load data rather than equipment quantity alone. Future expansion and required battery runtime should also be considered during system design.

How to Select an 80kVA Three-Phase UPS
Select the UPS according to the actual connected load in kW and kVA, input and output voltage, power factor, startup or peak demand, 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, communication interfaces and installation conditions for project configuration.
Selection and Project Planning
Confirm the exact power rating, input/output phase, voltage, frequency, power factor, battery voltage, runtime, bypass, communications, dimensions, environmental limits and installation method against the selected model and project drawings before ordering.
Frequently Asked Questions
Can this product be configured for a specific project?
