Legrand KEOR SP UPS 10–40 kVA

The Legrand KEOR SP is a three-phase industrial-grade online double-conversion UPS targeting data centres, mission-critical industrial control systems, medical facilities, and large commercial IT infrastructure at power levels from 10 kVA to 40 kVA per module. The 310155 model (20 kVA) employs IGBT-based three-level neutral-point-clamped (NPC) inverter technology to deliver a true sinewave output with a Total Harmonic Distortion below 2% — a level of power quality that protects sensitive drives, PLCs, and medical imaging equipment from the waveform distortion that would otherwise cause premature failure or measurement errors. The input power factor is above 0.99, minimising reactive current draw on the building's distribution system and reducing transformer sizing requirements in new projects — a genuine life-cycle cost benefit on large UPS installations. The N+X parallel redundancy capability allows multiple KEOR SP modules to operate in a fault-tolerant parallel configuration without a centralised bypass cabinet, so a single unit failure in a parallel bank does not interrupt the protected load.

The KEOR SP's on-board intelligence is centred on its ARM processor-based DSP control platform, which executes predictive battery state-of-health algorithms based on temperature-corrected Peukert modelling to provide accurate remaining runtime estimates under actual load conditions — a significant improvement over the simple voltage-based estimates displayed by lesser UPS systems. The battery management system extends battery life by automatically adjusting float voltage as a function of ambient temperature, reducing sulfation damage on the VRLA battery strings that are inevitable in Saudi Arabia's high ambient temperature conditions. The comprehensive communication suite includes RS-232, USB, dry contacts, and an integrated SNMP/web interface that provides browser-based real-time monitoring and alarms without requiring a separate network management card.

In the Saudi Arabian market the KEOR SP serves as the standard UPS backbone for Tier II and Tier III data centre deployments at government ministries, Saudi Telecom Company (STC) edge nodes, and the growing co-location data centre sector in Riyadh's technology corridor. NEOM's data and cloud infrastructure specifications reference three-phase UPS products at this performance class, and the KEOR SP meets the NEOM technical authority's requirements for VFI SS 111 classification, SNMP integration, and N+1 redundancy without the complexity of an external bypass maintenance switch. At Saudi Aramco and SABIC facilities, the KEOR SP protects the DCS and safety instrumented system (SIS) control room power infrastructure, where a power interruption would trigger process shutdowns with significant production cost consequences. The KEOR SP's operating temperature range of 0 °C to +40 °C (derated to 35 kVA above 25 °C on the 40 kVA model) covers the air-conditioned equipment room environments found across the Kingdom.

Razz Middle East is an authorised Legrand UPS distributor in Saudi Arabia, stocking the KEOR SP range in 10, 20, and 40 kVA configurations with local engineering support for sizing, installation, and commissioning. We provide battery autonomy calculations, N+X parallel configuration design, SNMP integration support, and annual preventive maintenance contracts for KEOR SP installations across Riyadh, Jeddah, Dammam, Jubail, and Yanbu. Our team holds Legrand-certified KEOR SP installation training and can provide equipment qualification documentation for ARAMCO, SABIC, and NEOM technical authority submission packages.
