Uninterruptible power supply ONLINE USV-Systeme YUNTO 800 0,8 kVA

The ONLINE USV-Systeme YUNTO 800 0.8 kVA is a Line-Interactive uninterruptible power supply designed to protect small networks, workstations and electronic devices from power interruptions and voltage fluctuations. With a rated output of 0.8 kVA (480 W), three AC outlets with C13 couplers and an internal 9 Ah battery, the unit provides brief backup power to allow safe shutdown or ride-through during short outages. The compact black housing and IP20 rating make it suitable for indoor rack- or desk-mounted installations where space is limited.

Advantages

The UPS provides stable output and automatic voltage regulation to compensate for undervoltage and overvoltage without switching to battery when possible. A typical backup time at full load is approximately 2.5 minutes, enabling controlled shutdown of connected equipment. With an efficiency of 95% and a lightweight 3.5 kg enclosure, the device balances energy performance with portability. Conformity to EN62040-2:2006 and CE ensures compliance with relevant safety and electromagnetic compatibility standards.

Suitable for

• Home or small office desktop computers and peripherals
• Network devices such as routers, small switches and modems
• Point-of-sale terminals and small embedded systems
• Controlled shutdown of single workstations and external storage during short outages
