Introducing the 5th Generation TriMOD UPS: 20 Years of Innovation

For two decades, Legrand has been at the forefront of power protection technology. With the launch of the 5th generation TriMOD UPS, the evolution of modular uninterruptible power supply systems reaches a new level combining flexibility, efficiency, and intelligent design to meet the demands of modern infrastructure. 

It is now 20 years since the first TriMOD UPS was developed. During that time, the requirements for reliable power have evolved significantly. The growth of digital systems, the expansion of data-driven operations, and the critical importance of uptime in sectors such as healthcare have all shaped the need for more adaptable solutions. The latest TriMOD reflects these changes, offering improved efficiency, enhanced scalability, and a level of flexibility that earlier generations could not achieve.

Power Range, Scalability and Performance

The TriMOD UPS is available in a wide power range from 10kVA to 80kVA within a single system. This allows it to support everything from smaller installations through to more demanding critical applications. For sites requiring additional capacity or redundancy, the system can be paralleled, enabling configurations of up to 160kW.

This scalability ensures that the UPS can grow alongside the application, avoiding the need for premature replacement and supporting long term infrastructure planning. Its modular design, based on self-configuring single phase power modules, also enables N+X redundancy, increasing system resilience and uptime.

High Efficiency and Unity Power Factor

Efficiency is a key consideration in modern UPS design, and the TriMOD delivers significant improvements in this area. With efficiency levels of up to 96.5%, it reduces energy losses and lowers operational costs compared to previous generations.

In addition, the system operates with a unity power factor (power factor = 1), meaning it can deliver its full rated power as usable output. This is particularly important in environments such as data centres, where maximising real power availability is critical.

Suitable Applications for the TriMOD UPS

The TriMOD UPS is designed to operate across a broad range of environments where power continuity is essential. In IT and data centre settings, it provides reliable protection for servers, networks, and storage infrastructure, ensuring operational continuity. In healthcare environments, it supports critical equipment where power interruption is not an option. Industrial applications benefit from stable backup for control systems and automation processes, while commercial buildings can maintain essential services without disruption.

Its modular design makes it particularly well suited to installations where future expansion or changing requirements are expected. Rather than committing to a fixed solution, organisations can deploy a system that evolves alongside their needs.

Independent Output Phases and Space Saving Design

One of the most compelling features of the TriMOD UPS is its ability to deliver three independent output phases from a single system. Within a 30kVA chassis, it is possible to configure up to three separate 10kW outputs. This effectively allows one unit to perform the role of three individual single-phase UPS systems.

This approach offers a clear advantage in terms of space efficiency and system simplicity. Instead of installing multiple units, a single TriMOD can support separate loads independently. This is particularly beneficial in applications where multiple isolated power supplies are required, such as separate IPS systems, as it reduces both physical footprint and installation complexity while maintaining full operational performance.

Configurable Phases and System Flexibility

The TriMOD UPS stands apart due to its configurable phase architecture. Built using single-phase modules, it can be arranged in a variety of configurations within the same chassis, including single phase input and output, three phase input with single phase output, full three phase operation, or single phase input with three phase output.

This versatility provides a significant advantage in real world installations. If site conditions change or infrastructure is upgraded, the UPS can be reconfigured rather than replaced. This avoids the cost and disruption associated with removing and reinstalling new equipment. In three-phase applications, the modular design also enhances redundancy, as the system does not rely on a single three phase block but instead distributes functionality across independent modules.

The Importance of 1:3 Phase Conversion Capability

A particularly unique capability of the TriMOD UPS is its ability to provide three phase output from a single phase input. This 1:3 configuration is rarely available in the UPS market and addresses a specific but important challenge.

Many facilities, especially smaller sites or older buildings, are limited to a single phase electrical supply while still requiring three phase power for certain types of equipment. Traditionally, this would necessitate costly infrastructure upgrades or the addition of external phase conversion equipment. The TriMOD simplifies this by integrating both functions into a single system.

As a result, it effectively acts as both a phase converter and a UPS with built-in battery backup. This makes it an ideal solution for environments where upgrading the incoming supply is impractical or too expensive. It enables organisations to run three phase loads from a compact footprint while maintaining full power protection.

Efficiency Improvements and Scalability

The 5th generation TriMOD UPS also delivers improved efficiency compared to previous models, helping to reduce energy consumption and operational costs. Alongside this, its ability to operate in parallel allows multiple units to be combined, either to increase overall capacity or to provide additional redundancy.

This scalability ensures that the system can grow with the needs of the application, making it a future proof investment for organisations that expect their power requirements to evolve over time.

Advanced Modular Design and Maintainability

The TriMOD’s modular architecture is built around hot-swappable single-phase power modules, allowing maintenance or upgrades to be carried out without shutting down the system. This helps to maximise uptime in critical environments.

Additional features such as plug-and-play functionality, automatic module recognition, and advanced monitoring via an intuitive touchscreen interface further enhance usability and operational control.

The system also supports flexible battery configurations, with VRLA batteries that can be installed internally or within external cabinets to extend runtime as required.

Conclusion: A Future-Proof UPS Solution

The 5th generation TriMOD UPS represents a significant step forward in modular power protection. Combining 20 years of development with modern engineering, it delivers a solution that is both highly adaptable and highly efficient.

With a power range from 10kVA to 80kVA, scalability up to 160kW, efficiency up to 96.5%, and a unity power factor, it meets the demands of today’s critical environments while remaining flexible for the future. Alongside features such as independent output phases, configurable architecture, and unique 1:3 capability, the TriMOD sets a strong benchmark for what a modern UPS system should deliver.
