What Is the DAXIN RM33 180kVA Modular Online UPS?
The DAXIN RM33 180kVA is a three-phase modular online UPS system designed for scalable critical-power protection in data centers, telecom facilities, industrial plants and other mission-critical applications.
Its modular cabinet architecture integrates power modules, centralized control, protection and service access within a scalable UPS platform, allowing installed capacity and redundancy to be configured according to project requirements.
The RM33 series supports 3 × 380/400/415VAC three-phase input and output, an input power factor of at least 0.99 at full load, input current THDi below 2% and system efficiency up to 96.5%.
Battery configuration, backup runtime, redundancy architecture, 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 cabinet instead of relying on a single fixed-capacity power stage.
This architecture allows capacity, redundancy and maintenance strategy to be planned according to the critical load, required availability and future expansion.
The DAXIN RM33 series combines modular power architecture, centralized control, external battery configurations and network-management options for scalable critical-power applications.
How Should an 180kVA Modular UPS Be Sized?
An 180kVA modular UPS should be sized according to the actual critical load in kW and kVA, load power factor, required redundancy, expected future expansion and battery autonomy.
Modular system design should also consider the number and rating of installed power modules, bypass architecture, upstream and downstream protection, communication requirements and maintenance strategy.
DAXIN ENERGY can review the load list, single-line diagram, required backup time and redundancy target before confirming the final RM33 system configuration.
