What Is the DAXIN 3H3 400K-T 400kVA Online UPS?
The DAXIN 3H3 400K-T is a 400kVA/360kW low-frequency 3/3 phase double-conversion online UPS designed for large industrial, data center, infrastructure and mission-critical power applications.
Its three-phase input and three-phase output architecture supports facilities operating large three-phase critical loads. The reference configuration supports 380/400/415VAC operation, an input power factor greater than 0.99 and input current THDi below 3%.
The UPS provides 400kVA apparent power and 360kW active power, with static output voltage stability of ±1%, dynamic voltage stability of ±5% within 10ms and a 3:1 crest factor.
Battery technology, bypass configuration, communication interfaces and other project options should be confirmed according to the required backup time, site electrical system and approved DAXIN technical proposal.
Battery Configuration Options
The DAXIN 3H3 400K-T can be engineered with different energy-storage technologies according to project requirements.
- Valve-regulated sealed lead-acid batteries
- Nickel-cadmium batteries
- Supercapacitor systems
- Lithium battery systems
- Flywheel energy-storage systems
The final battery technology, capacity and autonomy should be selected according to the connected load, required backup duration, operating environment, lifecycle requirements and project design.

¿Qué significa «3/3 fases» en un SAI?
Un SAI trifásico de 3/3 utiliza corriente alterna trifásica en la entrada y suministra corriente alterna trifásica en la salida.
This architecture is commonly used for high-capacity critical loads in data centers, industrial plants, power infrastructure, transportation systems and other facilities operating large three-phase electrical equipment.
The DAXIN 3H3 400K-T provides a 400kVA/360kW three-phase online UPS platform for these large critical-power applications.
What Should Be Considered When Selecting a 400kVA UPS?
A 400kVA UPS should be selected from the actual critical-load profile rather than nominal capacity alone. Review the connected load in both kW and kVA, power factor, peak demand, future expansion and required operating margin.
For large projects, also evaluate battery autonomy, bypass architecture, upstream and downstream protection coordination, generator compatibility, communication requirements, installation space, ventilation, floor loading and maintenance access.
The DAXIN 3H3 400K-T provides 400kVA apparent power and 360kW active power. DAXIN ENERGY can review the load list, single-line diagram and site conditions before final system configuration.
