Prostar MPS100K-50K modular online ups 100kva for medium data center is a scalable three-phase power protection solution. With online double conversion technology, it provides stable pure sine wave output. Modular online UPS 100kVA protects critical loads from power failures, voltage fluctuations, and electrical noise. The modular design supports N+1 redundancy and hot-swappable power modules, ensuring high reliability and easy maintenance.
With a capacity of 100 kVA, this modular UPS solution ensures that your data center operations remain uninterrupted, even during power fluctuations.

Modular Online UPS 100kVA Key Features
Modular Design
The modular architecture allows for flexible scalability, adapting to your growing power needs. Users can easily add or remove modules without system downtime.
N+1 Redundancy
Provides high reliability by allowing multiple UPS units to operate in parallel; if one unit fails, others continue to function without interruption.
Hot-Swappable Power Modules
Facilitates maintenance and upgrades without interrupting the power supply to critical systems.
High Efficiency
Operating in ECO mode can achieve efficiency levels of up to 98.5%, significantly reducing energy costs and heat generation.
LCD Touch Screen
Offers an intuitive user interface for easy monitoring and configuration, along with remote access for convenience and management.
Multiple Protection Functions
Features protections such as Over Voltage Protection (OVP), Over Current Protection (OCP), Over Temperature Protection (OTP), and short circuit protection, ensuring comprehensive safety.
Supports Parallel Operation
Allows for increased capacity and redundancy by connecting multiple UPS units in parallel, suitable for growing data center needs.
Modular Design for Flexible Expansion
The modular architecture of this modular online UPS 100kVA makes it ideal for projects requiring scalable power solutions. Users do not need to install a large traditional UPS from the beginning. Instead, they can build the system based on real demand, and can expand capacity later.
This modular UPS is designed with 50kVA/50kW power modules, allowing fast installation and flexible upgrades. When a module needs maintenance, it can be replaced quickly. This is possible through a hot-swappable structure, which significantly reduces system downtime. It also helps lower maintenance costs.

N+1 Redundancy for High Reliability
For critical load protection, system reliability is the top priority. The modular online UPS 100kVA supports N+1 redundancy, meaning the UPS can continue operating normally even if one module fails.
This redundancy structure ensures:
-
Continuous stable operation for critical loads
-
Lower risk of unexpected downtime
-
Increased overall system availability
-
Better protection for data center and industrial environments
True Online Double Conversion Technology
Modular online UPS 100kVA adopts online double conversion technology, which continuously converts AC power into DC and then back to AC. This process isolates the load from utility disturbances and provides stable output voltage and frequency.
Compared with line-interactive UPS systems, online UPS provides stronger protection against:
-
Voltage fluctuation
-
Frequency instability
-
Power surges and spikes
-
Electrical noise and harmonic distortion
-
Blackouts and brownouts
With 0ms transfer time, sensitive equipment will not reboot or shut down during power failure.
