Description
What Is the DAXIN RM33 300kVA Modular Online UPS?
The DAXIN RM33 300kVA is a three-phase modular online UPS system designed for large data centers, telecom facilities, industrial plants and other mission-critical power applications.
Its modular architecture integrates scalable power modules, centralized control, protection and service access within a common UPS platform, allowing installed capacity and redundancy to be planned according to the critical load and future expansion requirements.
The RM33-300kVA reference configuration provides 300kW cabinet capacity and supports 3 × 380/400/415VAC three-phase input and output, an input power factor of at least 0.99 at full load and external battery configurations.
Final power-module configuration, battery autonomy, redundancy architecture, bypass, communications and project accessories should be confirmed according to the connected load and approved DAXIN technical proposal.

What Is a Modular UPS System?
A modular UPS system uses multiple power modules within a common UPS platform instead of relying on a single fixed-capacity power stage.
This architecture allows installed capacity, redundancy and future expansion to be planned according to the critical load and required system availability.
The DAXIN RM33 series combines modular power architecture, centralized control, external battery configurations and optional network management for scalable critical-power applications.
How Should a 300kVA Modular UPS Be Sized?
A 300kVA modular UPS should be sized according to the actual critical load in both kW and kVA, load power factor, required redundancy, operating margin, expected future expansion and battery autonomy.
For large data center and industrial projects, system design should also consider power-module configuration, bypass architecture, upstream and downstream protection, generator compatibility, battery capacity, communications and maintenance requirements.
DAXIN ENERGY can review the load list, single-line diagram, required backup time and redundancy target before confirming the final RM33 modular UPS configuration.
Why Use a Modular UPS for Large Data Centers?
Modular UPS architecture allows data center operators to align installed power capacity with the actual critical load while preserving flexibility for redundancy and future expansion.
For growing facilities, additional capacity can be planned within the supported system architecture instead of treating every future load increase as a completely separate UPS project.
The DAXIN RM33 modular UPS platform is designed for scalable three-phase critical-power applications with external battery systems and network-management options.
