Continuous power availability has become increasingly important as organisations depend on digital infrastructure to keep operations running. In critical facilities, from data centres and healthcare sites to financial institutions and industrial environments, systems demand uninterrupted power, simple maintenance and the flexibility to grow as requirements evolve.
Legrand South Africa has launched its TriMOD three-phase modular uninterruptible power supply (UPS), a fifth-generation platform with a highly adaptable architecture combining resilience, scalability and ease of service. Available in ratings from 10 to 80 kW, the system features a modular design based on independent single-phase power modules.
Unlike conventional modular UPS systems, this design enables multiple input and output configurations within a single cabinet, allowing installers and specifiers to configure systems for a wide variety of applications while simplifying installation and allowing for future expansion.
One of TriMOD’s key advantages is modular scalability. Customers can increase capacity incrementally by adding lightweight power modules as demand grows, rather than replacing the complete UPS. The compact and lightweight power modules are designed for easy transportation, installation and servicing. Maintenance is further simplified through hot-swappable power modules and battery drawers, enabling servicing or replacement without interrupting power to critical loads. This minimises downtime and reduces maintenance costs while helping organisations maintain business continuity.
The design also enables multiple input and output configurations, including three-phase and single-phase combinations, allowing the same platform to accommodate different installation requirements. This flexibility is particularly valuable where facilities have mixed power distribution systems or where future infrastructure changes are anticipated.
TriMOD’s modular design strengthens system reliability through multiple levels of redundancy. Individual power modules operate independently, ensuring that if a module requires replacement or experiences a fault, the remaining modules continue supplying power to the protected load. Additional control board redundancy eliminates single points of failure, enhancing overall system availability in critical applications.
Legrand has focused on simplifying operation through an intuitive 5-inch touchscreen human-machine interface. The display provides real-time system monitoring, historical alarm logs and predictive diagnostic capabilities that assist maintenance teams in identifying potential issues before they affect operations.
The system delivers online double-conversion protection with efficiency of up to 96,5%, rising to 99% in Eco Mode, enabling organisations to reduce operating costs while maintaining high levels of power protection. Compatibility with generator systems and configurable battery backup options further enhance its suitability for demanding commercial and industrial environments.
TriMOD has been designed with sustainability in mind. Legrand incorporates circular economy principles into product development, focusing on repairability, component separation and extended product life. Digital documentation and monitoring tools further reduce paper usage while supporting preventative maintenance and lifecycle optimisation.
Legrand’s technical support capability includes project design assistance, installation supervision, commissioning, preventative maintenance programmes, operator training and emergency service support, providing customers with expert assistance throughout the lifecycle of their power protection systems.
