Core Technical Advantages Customized for Data Centers
1. N+X Distributed Redundancy to Eliminate Single Point of Failure
Each power module integrates independent rectifier, inverter, charger and static bypass circuit, adopting decentralized control + centralized management architecture. Faulty modules are isolated automatically without disrupting load sharing of remaining units.
- N+1 redundancy as standard for Tier III computer rooms to support live maintenance;
- N+2 high redundancy recommended for Tier IV carrier IDCs to reach 99.999% power availability and fully avoid service interruption caused by single component failure;
- Real-time alarm triggers when actual load exceeds set redundant capacity, while normal power supply is maintained within total cabinet capacity.
2. Full Hot-Swap Design for Minutes-Level Maintenance Without Shutdown
All power, monitoring and bypass modules support live hot plugging under full load:
- No power cut to servers, storage, switches and other IT equipment during capacity expansion or faulty module replacement;
- Conventional monolithic UPS requires over 4 hours full-unit power-off for maintenance, while CONSNAnt modular UPS limits MTTR within 15 minutes, drastically cutting outage risks and SLA compensation losses for multi-tenant IDCs;
- Universal interchangeable modules within the same series for unified spare parts inventory, reducing operators’ stocking costs.
3. Phased Elastic Capacity Expansion to Cut Upfront Investment & Optimize TCO
As cloud, AI and big-data businesses iterate gradually and computing power of data centers grows incrementally, CONSNAnt modular UPS delivers a “pay-as-you-grow” model:
- Deploy minimal modules matching current loads at initial construction to avoid one-time investment in idle capacity;
- Insert new power modules directly into existing cabinets during business expansion, with no cabinet replacement, massive cable reworking or machine room reconstruction;
- Take the 600kVA CNM330 cabinet as an example: start with 300kVA (6×50kW modules), then add modules to full 600kVA later. Upfront capital expenditure is reduced by nearly 40% compared with purchasing full-capacity UPS at one time.
4. High-Efficiency Topology for Green Low-Carbon Data Centers
- CNM331 3-level topology achieves peak efficiency of 97%; CNM330/CNME331 deliver system efficiency ≥96% under typical data center load rate of 50%–75%;
- Intelligent dormant rotation control: automatically hibernate redundant modules under light loads to concentrate loads on fewer operating units for high-efficiency operation, lowering UPS self-loss and matching air-condition cooling power consumption;
- Input power factor ≥0.99 with ultra-low harmonic distortion, reducing harmonic loss of power distribution cabinets and transformers, complying with domestic green data center PUE assessment and carbon reduction standards.
5. Ultra-Wide Grid Compatibility & Premium Clean Power Output
The full product line adapts to complex grid conditions of domestic and overseas data centers:
- CNME331 with ultra-wide 138–485Vac input suits unstable municipal power at suburban edge nodes and remote branch sites;
- CNM330/CNM331 tolerate ±20% nominal voltage fluctuation, maintaining stable operation under voltage sag, surge, flicker and harmonic interference;
- Pure sine wave output with crest factor of 3:1 fully protects high-density GPU servers, all-flash storage, core switches and optical transmission equipment from grid damage.
6. Intelligent Visual O&M & Proactive Fault Early Warning
- All cabinets are equipped with 7/10-inch touch LCD screens to real-time display input/output voltage, current, power, battery SOC, module operating status and historical fault logs;
- Diversified communication expansion cards support remote cloud monitoring and linkage with DCIM management platforms to realize unattended machine room operation;
- Early warnings for module overheating, battery aging, long-term overload and fan abnormalities convert passive emergency repair into predictive maintenance, reducing unplanned downtime frequency.
7. Flexible Mechanical & Wiring Design for Various Machine Room Layouts
- CNM330 vertical cabinets support top and bottom cable entry; standard version (maintenance bypass only) and full version (complete input/output switches) optional;
- CNME331 stacked compact units with casters for easy handling and layout in narrow small server rooms;
- Standardized cabinet size with neat wiring and centralized power distribution, greatly simplifying civil engineering and electrical integration construction of data centers.
