CyberPower UT800EG‑UK - 800 VA / 400 W Line Interactive UPS (Tower, 3 × UK outlets)

The UT800EG‑UK delivers reliable power backup and surge protection for PCs, network gear, POS systems, and home routers. With 800 VA / 400 W capacity, line‑interactive topology, and simulated sine wave output, it offers voltage stabilization and energy‑efficient standby operation in a compact tower form factor.

Key Features

• Automatic Voltage Regulation (AVR): Single‑boost/single‑buck AVR corrects under‑ and over‑voltage spikes (165–290 VAC) without draining the battery.

• Simulated Sine Wave Output: Suitable for general office electronics, though may have compatibility issues with Active PFC PSU systems.

• GreenPower UPS™ Bypass: Patented bypass design reduces idle power consumption and lowers heat generation, extending battery life.

• Surge & EMI/RFI Protection: Protects connected equipment from spikes and interference, including data line protection on selected models.

• Generator Compatibility: Tolerant of generator voltage fluctuations for backup scenarios.

• LED Indicators & Alarms: Displays status (Line, Battery, Bypass, Fault), and includes configurable audible alerts for battery low, overload, and faults.

Battery & Runtime

• Battery: Sealed lead-acid (non-user replaceable) with approx. 6-hour recharge time.

• Runtime Examples:

  • ~30 min at 60 W

  • ~18 min at 90 W

  • ~5 min at 200 W

  • ~2.5 min at full load (~400 W)
