Legrand VARING UPS 3 kVA Online

The Legrand VARING UPS is a compact single-phase online double-conversion uninterruptible power supply designed for protecting critical IT loads, networking equipment, and sensitive laboratory instruments in environments where power quality is as important as backup autonomy. The 310092 model provides 3 kVA / 2700 W of continuous output power with a true double-conversion online topology — meaning the connected load is always powered from a clean regulated inverter output that is completely galvanically isolated from the utility supply, eliminating the voltage spikes, sags, harmonics, and frequency deviations that are present on Saudi grid supplies serving industrial estates and commercial zones. The input power factor correction (PFC) stage accepts a wide input voltage range of 110–300 V AC without switching to battery, providing immunity to the voltage fluctuations that occur on SEC distribution feeders during peak summer demand periods in Riyadh and the Eastern Province.

The VARING 3 kVA includes a built-in SNMP card slot that accepts Legrand's NETMAN 204 or NETMAN 208 network management cards, converting the UPS into an SNMP-accessible network device that reports alarms, battery state of health, input/output measurements, and estimated runtime to the facility's network management system without additional hardware. The UPS supports automatic graceful shutdown of connected servers when battery runtime drops below a configurable threshold, protecting data integrity during extended power outages. The front panel LCD shows real-time input voltage, output voltage, load percentage, battery state of charge, estimated runtime, and fault codes — information that maintenance technicians require for rapid diagnosis without connecting a laptop. Two ECO operating modes reduce energy losses during periods of stable utility power, improving efficiency to over 98% by bypassing the inverter under controlled conditions while maintaining the ability to switch to full online protection in under 4 ms when the supply quality degrades.

Saudi Arabia's telecommunications infrastructure, banking sector, and healthcare IT systems rely heavily on UPS protection to maintain service continuity through the frequent power quality events on the SEC grid, including the brownouts that typically occur between June and September when ambient temperatures exceed 45 °C and cooling loads on the network are at their peak. The VARING UPS is deployed across server rooms in Saudi Aramco's upstream operations centres, Riyad Bank and Al Rajhi Bank branch IT rooms, King Fahd Medical City networking equipment rooms, and NEOM's construction-phase temporary communications infrastructure. The product's compliance with IEC 62040-1 and IEC 62040-3 (VFI SS 111) — the highest performance class for online UPS — satisfies the supply quality protection specification required by CITC-licensed operators and SEC grid-code-compliant independent power producers.

Razz Middle East supplies the full Legrand VARING range from 1 kVA to 10 kVA, including external battery packs for extended runtime applications. We stock common configurations including the 3 kVA and 6 kVA models and offer SAR-denominated pricing with delivery throughout Saudi Arabia. Our engineers provide site load surveys, battery autonomy calculations, and post-installation battery commissioning tests, and we maintain a stock of NETMAN SNMP management cards for immediate deployment on critical infrastructure projects.
