Vision Dual uses line interactive topology with Automatic Voltage Regulation — correcting input voltage brownouts and over-voltages without drawing from battery. Preserves battery capacity for genuine power failure events and extends battery lifespan.
Front-accessible batteries can be replaced without shutting down the UPS — keeping connected equipment protected throughout battery maintenance. Tool-free replacement in minutes.
Vision Dual outputs pure sine wave on battery — compatible with all modern servers, storage, and network equipment with active PFC power supplies. Avoids damage risk from simulated sine wave output.
Riello MultiPower software provides graceful shutdown of Windows and Linux servers, and VMware vSphere VM shutdown and vMotion before host shutdown on power failure. Included via USB or RS-232.
Front-panel LED indicators show AC power present, UPS on battery, battery charge level, load level, and fault conditions — providing immediate visual status without software or network.
Vision Dual is available with optional 5-year warranty covering both UPS electronics and battery — aligning protection period with server hardware lifecycle.
The Riello Vision Dual (VSD) is Riello's line-interactive UPS in the 1.1–3kVA range, designed for office server rooms, network cabinets, and SME IT infrastructure. Available in 1100VA, 1500VA, 2000VA, and 3000VA in both tower and rackmount formats, the Vision Dual covers the most common single-phase UPS requirements without the additional cost of full online double-conversion.
Pure sine wave output on battery is a critical specification — the Vision Dual's AVR corrects voltage fluctuations without battery consumption, and when the UPS switches to battery the pure sine wave output ensures compatibility with all modern hardware. Hot-swap front-accessible batteries simplify maintenance, and Riello MultiPower software provides graceful shutdown integration for common server and virtualisation platforms.
The optional 5-year warranty covering both UPS and battery aligns protection with typical server refresh cycles — a single procurement decision covering the full equipment lifecycle. Riello's manufacturing quality and strong European support network make Vision Dual a reliable alternative to APC Smart-UPS in the 1–3kVA line interactive segment.
Vision Dual covers the 1–3kVA range most commonly needed by SME server rooms — providing line interactive protection for 1–4 rack servers, NAS, switches, and VoIP infrastructure.
Tower VSD models protect network cabinets housing Cisco, Fortinet, or Juniper switches and routers — AVR corrects brownouts without battery use and pure sine wave output protects on battery.
Vision Dual protects clinical workstations, nurse call systems, and ward-level networking where power continuity is patient safety critical.
NVR recorders, IP camera switches, and access control systems are protected by Vision Dual — tower form factor and hot-swap batteries suit CCTV room and security cabinet installations.
