Electrical systems supplier Legrand South Africa says that its new range of service sector solutions, the uninterruptible power supply (UPS) system, enhances products such as structured cabling systems for data networks and control and management of installation equipment, including trunking and distribution systems.

Company GM Luk Ivens says that Legrand’s environment-friendly approach to constantly changing global markets encompasses ongoing technological developments of the company’s extensive product portfolio.

“Energy efficiency, quality power supply, optimum safety and enhanced aesthetics are critical to the advancement of all Legrand systems. The Legrand UPS system ensures continuity of service for installations in diverse industries and provides reliable performance in terms of power and backup time,” he explains.

In addition, the system’s optimum sizing of power stages, the latest electronic components and thorough testing of each unit ensure dependability and safety. Its batteries and efficient charging system have extended battery life by up to 50%.

This UPS system encompasses three ranges – the Modular series for a reliable power supply up to 120 kVA, the Conventional series up to 10 kVA and the Line Interactive series, which is a UPS system up to 3 kVA.

The compact and lightweight Modular series, which is easy to transport, install and maintain, is designed for applications requiring easy expansion. This flexible system is made up of standard modules that can be added to existing configurations to increase the power supply or backup time.

When necessary, power is easily expanded inside the cabinet, without having to reconfigure the installation. The backup time can be extended either by adding battery trays in the same cabinet, or by adding another cabinet, depending on the power of the UPS and the backup time required.

This modular three-phase system consists of individual single-phase modules which are redundant and self-configuring to enable power to be increased quickly and safely. Different levels of redundancy are easily obtained to ensure maximum continuity of service at all times.

“An advantage of a three-phase power supply system with single-phase loads is that, in the event of a failure of one of the modules, there is no loss of power. Power continues to be distributed over the other modules, which are still operational. With this system, it is also possible to create redundancy on each individual phase.

“If one power module fails, the other modules for this phase take over. In a failure of a UPS that includes several control modules, continuity of service is assured by the automatic distribution of lost power over the other modules,” Ivens concludes.
