With a power capacity of 650VA and 400W, this tower-style unit provides a stable energy backup for home and office devices, ensuring that your work remains uninterrupted and your hardware stays safe during electrical instability.

Advantages

This UPS offers robust protection for sensitive electronics by providing battery-backed power during blackouts and filtering harmful voltage fluctuations. The integrated USB connectivity allows for seamless communication with your computer or NAS, enabling automatic and safe system shutdowns to prevent data loss when the battery level is low.

  • Modems, routers, and media boxes
  • Small office communication equipment

This unit may not be suitable for high-power equipment such as laser printers, space heaters, or large server racks that exceed the 400W power limit. It is designed for low-to-medium power consumption devices and should not be used to power appliances with high startup current requirements.

To use the APC Back-UPS, place the unit in a well-ventilated area near your equipment. Connect your devices to the C13 outlets on the back of the unit.

Once connected to a wall outlet, turn the device on using the power button. The UPS will automatically begin charging its internal battery and monitoring the power supply to your connected hardware.

What to consider before purchase

  • Verify that the total power consumption of your connected devices does not exceed 400W.
