Product information

Description

The Eaton 3S550I is a standby (offline) uninterruptible power supply designed to provide short-term backup power for home and small office equipment. With an output power capacity of 0.55 kVA (330 W) and eight AC outlets, this compact UPS uses sealed lead acid (VRLA) battery technology to maintain basic operation of connected devices during power interruptions. The unit is available in white and black finishes and comes with a 1.5 m power cable; it carries CE/EAC/Ukr/Cm/CB report certifications for compliance with relevant safety and performance standards.

Advantages

The Eaton 3S550I delivers immediate transfer to battery power in the event of mains failure, protecting equipment from data loss and abrupt shutdowns. Its eight AC outlets allow multiple devices to be connected simultaneously while the built-in USB 2.0 port supports basic communication and monitoring. The sealed lead acid (VRLA) battery technology provides reliable backup power with simple maintenance requirements, and the unit’s compact form factor and modest weight of 3.2 kg make it suitable for placement on or under a desk.

Suitable for

  • PCs, monitors and home office workstations
  • Network devices such as routers and small switches
  • Peripherals like external drives, printers and VoIP phones
  • Point-of-sale terminals and small retail systems

  • Topology: Standby (Offline) UPS
  • Battery type: Sealed Lead Acid (VRLA)
  • AC outlets: 8
  • USB: 1 × USB 2.0 port

How to use

Place the Eaton 3S550I on a stable, ventilated surface away from direct heat sources and liquids. Connect the UPS to mains power using the supplied cable and plug your devices into the AC outlets. For basic monitoring, connect the USB 2.0 port to a computer if software is available; otherwise the UPS will automatically switch to battery when mains power fails. Periodically check the battery condition according to the manufacturer’s maintenance guidance and replace the sealed lead acid battery when end-of-life indications appear or runtime degrades significantly.

Usage recommendations

Use the UPS to protect critical equipment from short-term outages and to allow orderly shutdown of systems. Avoid connecting equipment that exceeds the 330 W output rating and refrain from placing heavy objects on the unit. Maintain ambient temperature within the manufacturer’s recommended range, perform occasional battery self-tests if supported, and replace the VRLA battery at the end of its service life to ensure continued backup availability.
