30kVA-300kVA Modular UPS
30–300kVA High-Capacity Modular UPS with Scalable Architecture and N+X Redundancy for Large Data Centers, Industrial Systems and Mission-Critical Infrastructure
ShanPu 30kVA-300kVA modular UPS is a three-phase online double-conversion UPS built on a 30kVA hot-swappable power module, designed for larger commercial, industrial and critical power applications. Cabinets accept 3, 5 or 10 modules, covering 30-90kVA, 30-150kVA and 30-300kVA. Output is regulated 380/400/415Vac pure sine wave at power factor 1.0 with 0ms transfer between mains, bypass and battery modes, system efficiency reaches 95.5% and input power factor stays ≥0.99, while cabinet charging current of up to 100A and ±180V to ±300Vdc battery banks support demanding backup requirements.
How the Modular UPS Works
The 30-300kVA modular UPS uses an online double-conversion power architecture to continuously regulate the power delivered to critical loads.
When utility power is normal, the rectifier converts incoming AC power into DC power. The inverter then converts the DC power into regulated AC power for the connected equipment. This continuous conversion process helps protect sensitive loads from utility voltage fluctuations, electrical noise and other power-quality problems.
The battery system is maintained in a ready-to-use condition during normal operation. When the utility supply is interrupted, the battery immediately supplies energy to the inverter, allowing the inverter to maintain AC output to the connected load.
The UPS achieves its overall capacity through multiple power modules operating together. The modular architecture allows the system to balance active capacity and redundant capacity according to project requirements. As the facility's load grows, additional modules can be incorporated to increase available UPS capacity without replacing the entire system.
Key Features
High-Capacity 30-300kVA Platform
Covering up to 300kVA, this modular UPS provides a higher-capacity solution for facilities with larger power requirements. It is suitable for projects that need substantial UPS capacity while retaining the flexibility of a modular architecture.
Scalable Power for Growing Infrastructure
The modular design allows capacity to be planned in stages. Facilities can deploy the required capacity initially and expand the system as electrical demand increases, making the UPS suitable for long-term infrastructure development.
N+X Redundancy for Mission-Critical Applications
Multiple power modules can work together to provide the required load capacity while additional modules can be reserved for redundancy. This architecture helps improve system availability and provides greater operational flexibility.
Reduced Maintenance Complexity
Each power module operates as part of the larger UPS system, making system diagnosis and maintenance more structured. Modular servicing can help reduce the disruption associated with maintaining a large UPS installation.
Intelligent Digital Control & Remote Monitoring
DSP digital control provides precise management of UPS operation. RS485 communication and optional SNMP connectivity can be used to integrate the UPS into centralized monitoring and management systems.
Applications
Large Data Centers
The 30-300kVA modular UPS is designed for larger data center environments with substantial and continuously growing power requirements. Its scalable architecture provides a practical way to increase UPS capacity as computing, storage and network loads expand.
Telecom & Network Facilities
Telecommunication and network facilities require dependable power for communication infrastructure and supporting equipment. The UPS provides continuous online power protection and can be configured to meet the availability requirements of critical network loads.
Industrial Automation & Manufacturing
Manufacturing plants can use the UPS to protect automation systems, industrial controllers, monitoring equipment and other critical loads. Stable power helps minimize disruptions that could affect production processes and control operations.
Financial & Mission-Critical Infrastructure
Financial institutions and other mission-critical facilities require high power availability for IT infrastructure and essential systems. The modular UPS supports redundant configurations to provide additional protection against power module failures.
Large Commercial & Public Facilities
Large commercial complexes, government facilities and infrastructure projects can use the UPS to provide centralized power protection for IT systems, communication equipment and other important electrical loads.
Typical Configurations
Step 1 - Size the load. Add up the connected critical load in kW and convert at power factor 1.0; select the cabinet whose module count covers both the load and the required redundancy level.
Step 2 - Choose the cabinet by module count. ECOplus 90-30 (3 modules, 30-90kVA), 150-30 (5 modules, 30-150kVA) or 300-30 (10 modules, 30-300kVA).
Step 3 - Set the redundancy level. Define N+X by installing modules beyond the minimum required by the load, and decide between multi-unit parallel redundant deployment and high-reliability standalone operation.
Step 4 - Match the battery and environment. Select the battery string voltage from ±180V to ±300Vdc (30-50 cells optional); module charging current is 10A and cabinet charging current is 30A / 50A / 100A. Install within 0-40°C, 0-95% RH (non-condensing) and below 1500m altitude (derate 1% per 100m above 1000m).
