## Long description

The Riello VST 800 is a line-interactive UPS with 0.8 kVA (640 W) capacity designed to protect peripheral network devices, servers and small network backup systems. The unit delivers a sinusoidal output, includes an LCD display for status, and offers advanced communications options with USB or RS232 and an expansion slot for additional interface cards. The compact black tower design has four AC outlets and a sealed lead-acid battery with a typical recharge time of 6 hours.
Advantages
The VST 800 uses LINE INTERACTIVE technology with an automatic voltage regulator (AVR) to correct surges, overvoltages and undervoltages without using the battery, improving battery availability for genuine power failures. Efficiency reaches high levels, reducing energy consumption, and EMI filters add protection against voltage transients. An EnergyShare socket supports load shedding to extend runtime for critical equipment, and Hot Swap front-accessible batteries simplify maintenance. The unit also features Cold Start capability and a shut-off button to reduce consumption to zero during prolonged inactivity.
Suitable for
Protecting small servers and network appliances
Workstations and office PCs
