## Long description

The Riello VST 1100 is an uninterruptible power supply (UPS) with a capacity of 1.1 kVA (880 W) designed to provide continuous, sinusoidal backup power for critical equipment. Using Line Interactive technology and an automatic voltage regulator (AVR), the unit corrects overvoltages and undervoltages without using the battery, while EMI filtering and surge protection reduce the impact of mains disturbances. The UPS includes four AC outlets, a backlit LCD for status and measurements, user-replaceable hot-swap batteries and an EnergyShare socket to prioritise runtime for essential loads.
Advantages
The VST 1100 delivers high efficiency (up to 98%) to minimise energy consumption and preserve battery capacity for actual outages. AVR and EMI filters protect connected equipment from voltage fluctuations and transients. Hot-swap batteries, an internal battery test and deep-discharge protection increase availability and simplify maintenance. The LCD display and multi-platform communications (USB or RS232, optional interface cards and PowerShield3 software) provide clear monitoring and controlled shutdown across major operating systems.
Suitable for
Small office servers and NAS devices
Workstations and desktop PCs requiring clean sinusoidal output
Network equipment (switches, routers) and modems
Point-of-sale terminals and small medical/industrial devices

How to use
Connect the UPS to mains power and plug critical devices into the provided AC outlets. Configure the EnergyShare socket to allow non-critical loads to be shed to extend runtime for essential equipment. Use the backlit LCD to monitor load, battery status and alarms. For automated shutdowns, install the PowerShield3 software on supported systems and connect via USB or RS232. To replace batteries, perform a hot-swap via the front panel following the safety instructions in the Riello user manual.
Usage recommendations
For optimal performance, place the UPS in a ventilated, temperature-controlled environment, avoid connecting high inrush loads (such as large motors or pumps) and schedule periodic battery tests. Use the EnergyShare function to prioritise critical equipment during extended outages and replace batteries according to the manufacturer’s maintenance intervals.
