Scalable Online Double Conversion UPS Systems With Lithium Ion Batteries

Salicru introduced 6 kVA and 10 kVA models to its SLC TWIN RT3 LION series, expanding the existing line of lithium-ion uninterruptible power supply systems. This integration of higher power ratings provides a single technological architecture for deployment across a broad spectrum of critical systems. The expanded range satisfies the rigorous availability requirements of data centers, high-density server racks, virtualization systems, and small communication hubs.

Technical Architecture and Power Factor Optimization
The upgraded series utilizes continuous online double-conversion technology to isolate connected loads from electrical grid disturbances. This architecture ensures complete protection against complete power outages, micro-cuts, voltage fluctuations, and harmonic distortions. Every unit in the series operates with a unitary power factor (PF=1). This specification guarantees that the apparent power in volt-amperes equals the active power in watts, allowing the system to deliver maximum active power to the connected loads without energy losses due to reactive components.

Battery Chemistry Performance and Infrastructure Integration
The transition from traditional valve-regulated lead-acid batteries to latest-generation lithium-ion chemistry alters the operational lifecycle of the equipment. Lithium-ion batteries yield a significantly longer service life, reduced routine maintenance overheads, accelerated recharge cycles, and superior energy density. These chemical attributes directly lower the total cost of ownership and minimize the physical footprint required within server rooms.

To maintain compatibility with diverse structural layouts, the units retain a versatile convertible rack and tower mechanical design. This enables secure mounting inside standard nineteen-inch rack cabinets or standalone floor placement. Remote supervision and preventive diagnostics are executed via integrated connectivity interfaces that continuously report system status. Furthermore, the 6 kVA and 10 kVA models include an adaptable power distribution unit designed for either rack integration or vertical mounting, which streamlines cable management and load connections in dense IT environments.

Additional Context
This section details technical specifications and competitive benchmarking not included in the original product announcement.

The expansion of the SLC TWIN RT3 LION series positions it alongside established industry solutions like the APC Smart-UPS Ultra and the Eaton 9PX Lithium-Ion series. In high-density IT environments, volumetric efficiency and weight are primary benchmarking criteria. Lithium-ion systems typically offer up to a 50 percent reduction in weight and a 40 percent reduction in physical space compared to traditional lead-acid alternatives.

While competitive standard double-conversion systems often operate at power factors between 0.8 and 0.9, the unitary power factor (PF=1) utilized by Salicru matches the highest modern efficiency standards, ensuring that a 10 kVA system delivers a full 10 kW of active power. Additionally, lithium-ion cells maintain an operational lifespan of 8 to 10 years under standard operating conditions, compared to the 3 to 5 years typical of lead-acid cells, effectively minimizing battery replacement intervals and associated operational disruptions in data center environments.
