ADVANCED uninterruptible power supply (UPS) systems ensure maximum continuity of service of essential electrical equipment, by providing reliable performance in terms of power and back up time, particularly during electrical network disturbances like load-shedding.

That’s according to Legrand, which claims that its UPS systems incorporate high performance batteries and an efficient charging system which extend battery life by up to 50%. They encompass three ranges: Line Interactive, Conventional and Modular.

Line Interactive UPS systems comprise units from 600 VA up to 3 kVA single phase. This range is ideal for small office and home use.

Conventional UPS systems, for power from 0,8 kVA to 800 kVA, in single and three phase, offer the commercial sector safe, efficient and innovative solutions, including reliable electrical redundancy. The design of this range offers flexibility in semi-modularity, whereby the autonomy and power can be expanded as required.

Legrand’s compact and lightweight Modular series, from 1,25 kVA to 800 kVA, is a flexible three-phase system, comprising individual single-phase modules that can be added to existing configurations to increase the power supply or backup time.

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.

The modular functionality of the batteries enables the removal of faulty batteries, or to increase the autonomy by adding batteries as required.
A range of communications accessories has been designed for managing and configuring the UPS, as well as for remote control of the system. These include network interfaces for real time control of the UPS and for managing numerous events that include no power, over-loads and by-pass problems.

These network interfaces, with a 32-bit processor, do not require any external software. Other accessories include sensors for monitoring ambient temperature and humidity, smoke detectors and fire safety controls, as well as air conditioning fault and intrusion detectors.

Communication and supervision software for accessing the operating parameters of the UPS and for carrying out full diagnostics and the configuration of specific functions, is also available. Legrand’s online site configurator www.ups.legrand.com assists with the selection of the correct UPS, by providing easy power selection and calculation of the necessary back-up time required.

Legrand South Africa offers full a service centre providing full technical support, service level agreements as well as critical spares backup.
