Product information

Description

The Ever DUO 550 AVR USB is a line-interactive uninterruptible power supply (UPS) designed to protect home and office equipment from power drops, surges and outages. With 0.55 kVA (330 W) output capacity, four C13 AC outlets and a USB Type-B port, it safeguards computers, monitors, telecom devices such as switches and routers, and fiscal equipment. The unit uses a sealed 12 V, 5 Ah lead‑acid battery in a compact tower housing with IP20 protection.

Advantages

The UPS integrates AVR (automatic voltage regulation) to correct low or high mains voltage without using battery power, reducing unnecessary battery discharge. A built-in HID USB interface allows basic communication with a computer without additional drivers, while the optional PowerSoft software provides monitoring and configuration of operating mode, load, battery charge and estimated runtime. The device supports cold start and automatic restart when mains power is restored after deep discharge.

Suitable for

  • Home desktop computers and monitors
  • Small office workstations and POS/fiscal devices
  • Telecom equipment: routers, switches and small network devices
  • Peripherals requiring short-term power backup during outages

Key specifications

  • Output power capacity: 0.55 kVA (330 W)
  • Outlets: 4 × C13 (AC outlets)
  • Battery: sealed lead‑acid, 12 V, 5 Ah
  • Communication: USB Type‑B (HID), PowerSoft software supported
  • Form factor and protection: compact tower, IP20
  • Weight: 3.8 kg
  • Colour: Black
  • Brand / Model: EVER / DUO 550 AVR USB (MPN: T/DAVRTO-000K55/00, EAN: 5907683605124)

How to use

Place the UPS on a stable, ventilated surface and connect the critical devices to the C13 outlets. Charge the internal battery by connecting the UPS to the mains before first use. Use the USB Type‑B connection to attach the unit to a computer for status monitoring; no driver installation is required for basic HID communication. For extended monitoring and configuration, install the PowerSoft software and follow the on‑screen instructions to view load, battery charge and runtime estimates. In case of extended mains failure the UPS will supply connected equipment from the internal battery until the battery is depleted; when mains power returns the unit will automatically restart the connected equipment. To perform a cold start, press the power button while the UPS is disconnected from mains.

Usage recommendations

Place the UPS away from heat sources and liquids, perform periodic battery self‑tests and replace the battery according to manufacturer guidelines. Avoid overloading the UPS beyond its rated 330 W output to ensure reliable backup and battery longevity.
