Description
What Is the DAXIN 3H3 300K-T 300kVA Online UPS?
The DAXIN 3H3 300K-T is a 300kVA/270kW 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 specification supports 380/400/415VAC input, an input power factor greater than 0.99 and input current THDi below 3%.
The UPS provides 300kVA apparent power and 270kW 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 selected according to the required backup time, site electrical system and approved DAXIN technical proposal.

Battery and Energy Storage Options
The DAXIN 3H3 300K-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 energy-storage technology, capacity and backup autonomy should be selected according to the connected load, required runtime, operating environment, lifecycle requirements and approved project design.
How Much Load Can a 300kVA UPS Support?
The DAXIN 3H3 300K-T is rated at 300kVA apparent power and 270kW active power. The actual connected load should remain within the approved operating limits and should include an appropriate design margin.
UPS sizing should consider the actual load in both kW and kVA, load power factor, startup or peak demand, future expansion, redundancy requirements and required battery autonomy.
For large critical-power projects, DAXIN ENERGY can review the load list and single-line diagram before confirming the final UPS and battery configuration.
Que signifie « 3/3 phases » dans un onduleur ?
Un onduleur triphasé 3/3 utilise une alimentation triphasée en courant alternatif en entrée et fournit une alimentation triphasée en courant alternatif en sortie.
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 300K-T provides a 300kVA/270kW three-phase online UPS platform for these large critical-power applications.

How to Select a 300kVA Three-Phase UPS
Select the UPS according to the measured critical load in kW and kVA, power factor, peak demand, input and output voltage, required operating margin, future expansion, battery autonomy, bypass architecture, redundancy target, communication requirements and installation environment.
For a 3/3 phase UPS, confirm that both the facility electrical supply and protected critical loads require three-phase power.
Large-capacity UPS projects should also evaluate upstream and downstream protection coordination, generator compatibility, battery-system architecture, maintenance access, ventilation, floor loading and system redundancy before final equipment selection.
Provide DAXIN ENERGY with the load list, single-line diagram and site requirements for project-specific UPS and battery configuration.
