Modular Online UPS Key Features
True Double Conversion Online Technology
Provides continuous, clean, and stable power by isolating critical loads from all utility power anomalies, including sags, surges, harmonics, and outages. Zero transfer time to battery mode ensures uninterrupted power supply during grid failures.
Modular Scalability
Built with 50kVA hot-swappable power modules, allowing seamless capacity expansion from initial deployment up to 600kVA (12 modules in parallel).
High Efficiency (Online Mode)
-
Peak Efficiency: Up to 95.5% in double-conversion mode.
- Eco-Mode Efficiency: Up to 98.5%.
The high efficiency reduces heat dissipation. It lowers cooling requirements and operational costs. As a result, there is a lower TCO (Total Cost of Ownership) and PUE (Power Usage Effectiveness) for your facility.
Advanced Redundancy (N+X)
The modular architecture allows for configurable redundancy. Users can configure the system for N+1 or N+X redundancy. This setup ensures that if one module fails, the remaining modules instantly take over the full load. There is no interruption, guaranteeing 100% load availability.
Hot-Swappable Design
Power modules, control units, and fan assemblies can be replaced without shutting down the system or interrupting protected loads.
Remote Management
The system is equipped with multiple communication slots for SNMP, Modbus, and TCP/IP protocols. This allows seamless integration with data center infrastructure management (DCIM) platforms and remote monitoring tools.
Compact Footprint & Flexible Installation
Space-saving rack-mount or floor-standing design fits seamlessly into existing infrastructure. Top or bottom cable entry options simplify installation in diverse facility layouts.
Modular Online UPS 600kVA Diagram
The system is constructed using hot-swappable 50kVA power modules. A standard cabinet can house up to 10 modules to achieve the full 600kVA capacity. These modules are “Plug-and-Play.” If a module fails, it can be removed and a new one inserted while the UPS remains online. This reduces the Mean Time to Repair (MTTR) to minutes. It also eliminates the need to switch the critical load to unprotected bypass power. More details: MPS50K 3 phase modular ups hot-swappable power module 50kW
Modular UPS System in Parallel: Up to 1.2MVA
For enterprise environments that need more power capacity than a single unit, modular online ups 600kva supports seamless system-level parallelization. It is also suitable for environments requiring the highest levels of fault tolerance. By connecting two 600kVA Modular Online UPS systems in parallel, organizations can achieve a massive 1.2 MVA (1200 kVA) power protection solution. This configuration offers the inherent benefits of internal module redundancy. The modular online ups also provides system-level redundancy. Together, these create an ultra-resilient power infrastructure. This is ideal for hyperscale data centers, large industrial plants, and critical national infrastructure.
The parallel architecture minimizes risks associated with power failure, as multiple modules provide backup support. Users can start with a smaller capacity and expand the system as required, making it a scalable investment. A centralized control system can monitor multiple modules, simplifying management and maintenance tasks.
