What Is the DAXIN 3H3 400K-T 400kVA Online UPS?<\/h2>\n
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.<\/p>\n
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%.<\/p>\n
The UPS provides 400kVA apparent power and 360kW active power, with static output voltage stability of \u00b11%, dynamic voltage stability of \u00b15% within 10ms and a 3:1 crest factor.<\/p>\n
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.<\/p>\n
Battery Configuration Options<\/h2>\n
The DAXIN 3H3 400K-T can be engineered with different energy-storage technologies according to project requirements.<\/p>\n
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.<\/p>\n

Que signifie \u00ab 3\/3 phases \u00bb dans un onduleur ?<\/h2>\n
Un onduleur triphas\u00e9 3\/3 utilise une alimentation triphas\u00e9e en courant alternatif en entr\u00e9e et fournit une alimentation triphas\u00e9e en courant alternatif en sortie.<\/p>\n
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.<\/p>\n
The DAXIN 3H3 400K-T provides a 400kVA\/360kW three-phase online UPS platform for these large critical-power applications.<\/p>\n
What Should Be Considered When Selecting a 400kVA UPS?<\/h2>\n
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.<\/p>\n
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.<\/p>\n
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.<\/p>\n
