Description
What Is the DAXIN 3H3 20kVA 3/3 Phase Online UPS?
The DAXIN 3H3 20kVA is a 20kVA/16kW 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
- 20kVA / 16kW Capacity: Designed for medium-capacity critical three-phase loads in industrial and infrastructure applications.
- 3/3 Phase Architecture: Three-phase input and three-phase output support critical three-phase electrical systems.
- Low-Frequency UPS Design: Intended for demanding industrial and infrastructure power-protection 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 connected load and required backup duration.
- 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 critical three-phase loads in industrial facilities, server rooms, telecom infrastructure, healthcare systems and transportation applications.
The DAXIN 3H3 20kVA uses this three-phase input and three-phase output architecture for applications requiring reliable 20kVA-class power protection.
20kVA vs 30kVA UPS: Which Capacity Should You Choose?
The DAXIN 3H3 20kVA reference model is rated at 20kVA/16kW, while the 30kVA model provides additional capacity for larger connected loads and future expansion.
The correct UPS capacity should be selected according to actual load in kW and kVA, power factor, startup or peak demand, required operating margin, future expansion and battery runtime.
DAXIN ENERGY can review the load list and project requirements before final model selection.
