Legrand’s Keor SPE RT UPS solutions ensure dependable performance in homes, small offices and guest houses
Eco-friendly UPS solutions where they matter
Legrand’s Uninterruptible Power Supply (UPS) solutions encompass the Keor SPE RT rack series, designed to deliver intelligent and efficient network power protection in homes, small businesses, shops and guest houses.
Uninterruptible Power Supply (UPS) systems are critical for transitioning and emergency backup power for a short period, until an alternative power source can be established, or the initial power source is restored.
In residential and small-scale commercial installations, this compact, easy to operate system is perfect for dependable backup power for lighting, electrical devices and for small IT cabinets, as well as home office equipment. A UPS system allows computers, the internet server and other home office equipment to continue operating, even when the power goes off. A UPS system is also designed to protect computers and other electronic equipment from surges in electricity, as the power goes off and back on, by maintaining a steady flow of power to machines.
Security is another important factor during power outages, especially in residential and guest house environments. Keor SPE RT units are compatible with home generators and provide the backup necessary before the generator kicks in, ensuring ongoing performance from a CCTV system, until power is restored.
The single-phase Keor SPE RT range, with power ratings from 750 VA to 3000 VA, is an uninterruptible power source with line-interactive technology and pure sinewave output, that delivers enhanced flexibility, energy efficiency and serviceability for critical systems.
Keor SPE RT units – equipped with a reversable LCD display with intuitive navigation and a three-colour LED bar for real-time status indication – have been developed by Legrand to integrate seamlessly within 19″ rack and tower configurations. Other features of this user-friendly UPS include hot-swappable VRLA batteries, accessible from the front panel, as well as programmable outlets for load prioritisation. An electronic stabiliser (AVR) inside the UPS provides the connected loads with effective protection against any interference in the electrical mains.
This system, with a configurable power factor ranging from 0.7 to 0.9 depending on the model, and output voltage options adjustable between 200 V and 240 V, supports a wide input voltage range of 175 V to 288 V at full load, ensuring robust performance in fluctuating mains conditions. The cold-start capability and comprehensive self-diagnostic features enhance system uptime, while USB, RS232 and SNMP ports allow simultaneous communication and system monitoring. An emergency power-off (EPO) function and two dry contacts are provided for integration with site-wide safety protocols.
The Keor SPE RT operates with minimal acoustic emissions, ranging from under 40 dBA to a maximum of 55 dBA, depending on model. Operating temperatures range from 0°C to 40°C with a relative humidity tolerance up to 95% non-condensing.
This system is available from Legrand in 1U, 2U and 3U variants. Backup autonomy varies, reaching up to 12 minutes, depending on load characteristics of the model. Extended runtime options are enabled through compatible external battery cabinets on 2U and 3U models.
As part of Legrand’s ongoing strategy to reducing environmental impact, the company advances research and development efforts to improve the sustainability of UPS products. The integration of circular economy principles, efficiency-driven design and rigorous environmental impact assessments, positions the company as leaders in promoting eco-conscious energy solutions. High efficiency in UPS operation results in lower energy consumption and reduced cooling requirements, lowering the environmental impact of the product over its operational lifetime.
The Legrand team offers a complete range of UPS solutions and services throughout Southern Africa, including technical pre-sales support at the project design stage, supervision of the installation, testing and commissioning, site acceptance tests and audits, as well as operator training. Legrand technicians perform comprehensive checks of every UPS installation to ensure safety and fault-free operation.
