UPS Uninterruptible Power Supply — Battery Backup for Computer, Router & Electronics

Keep Working When the Power Goes Out.

A UPS (Uninterruptible Power Supply) is the device that stands between a power outage and a lost document, a corrupted file, or a crashed system. When the grid goes down, the UPS switches to battery power in milliseconds — fast enough that your computer, router, or NAS never even notices the interruption. It also conditions the power coming in, protecting your equipment from surges, spikes, and voltage fluctuations that cause silent damage over time.

Features

• Battery backup — switches to battery power automatically during outages; provides enough runtime to save work and shut down properly
• Automatic voltage regulation (AVR) — corrects under-voltage and over-voltage conditions without switching to battery, extending battery life
• Surge protection — protects connected equipment from power surges and spikes on all outlets
• Pure sine wave output — clean AC power safe for sensitive electronics including desktop computers, servers, and medical equipment (check variant for sine wave vs. simulated sine wave)
• Multiple outlets — battery-backed and surge-only outlets for connecting different device types
• LCD display — shows battery level, load percentage, input voltage, and estimated runtime
• USB communication port — connects to a computer for automatic shutdown software integration
• Audible alarms — alerts for power failure, low battery, and overload conditions
• Replaceable battery — internal battery can be replaced when it reaches end of life without replacing the entire unit

Who It’s For

• Home office workers who need to protect computers and work during power outages
• Gamers who want to avoid losing progress during unexpected power interruptions
• Network administrators who need routers, switches, and NAS devices to stay online during outages
• Anyone with sensitive electronics that need protection from power quality issues

How to Use

1. Connect the UPS to a wall outlet.
2. Connect your computer, monitor, router, and other critical devices to the battery-backed outlets.
3. Connect non-critical devices (printers, lamps) to the surge-only outlets.
4. Power on the UPS — it will begin charging the internal battery.
5. Install the USB communication software on your computer for automatic shutdown during extended outages.
6. Test the UPS by unplugging it from the wall — connected devices should continue running on battery.

Frequently Asked Questions

How long will it power my computer during an outage?
Runtime depends on the UPS battery capacity and the total load connected. A typical desktop computer (300–500W) on a mid-size UPS provides 5–15 minutes of runtime — enough to save work and shut down properly. Check the variant’s runtime chart for your specific load.

How often does the battery need to be replaced?
UPS batteries typically last 3–5 years depending on usage and temperature. The UPS will alert you when the battery needs replacement. Replacement batteries are available separately.

Does it protect against lightning strikes?
A UPS provides surge protection against typical power surges. A direct or nearby lightning strike can overwhelm any surge protector. For maximum lightning protection, unplug equipment during severe electrical storms.
