What is an Uninterruptible Power Supply (UPS)?
APC, a flagship brand of Schneider Electric, offers UPS options for Computers & Peripherals, Networks & Servers, as well as Data Centres & Facilities.
Home: The electronic devices you rely on every day for communication, security and entertainment are at risk of damage and failure due to unexpected blackouts, voltage fluctuations or other power disruptions. A UPS provides battery backup power and protection for electronic devices, including:
- Wireless networking equipment (routers, modems)
- Security systems
- Gaming consoles
- Mobile devices
Business: Downtime caused by power outages is frustrating for anyone, but can be financially crippling for a business or organisation. Every year, billions of dollars are lost due to downtime caused by power disruptions that could have been prevented by a UPS. For Fortune 1000 companies:
- Average annual cost of unplanned downtime, $1.25—$2.5 billion
- Average hourly cost of infrastructure failure: $100,000
- Average hourly cost of critical application failure: $500,000—$1 million
Small to medium-sized businesses may be at most financial risk due to a limited ability to generate revenue during downtime.

What are some key features to understand when choosing a UPS system?
- User-Replaceable Batteries - Increases availability by allowing trained users to perform battery upgrades and replacements.
- Surge-Only Outlets - Protect secondary electronics from surges and spikes without reducing battery power used to run primary electronics during outages.
- Building Wiring Fault Indicator - LED indicator that informs users of potentially dangerous wiring problems in wall circuits.
- Transformer-Block Spaced Outlets - Protect equipment without blocking access to other receptacles.
- Automatic Self-Test - Periodic battery check that ensures early detection of batteries needing replacement.
- Automatic Voltage Regulation (AVR) - Gives high application availability by correcting low and high voltage conditions without using the battery.
- Pure Sine-Wave Output on Battery - Simulates utility power to provide the highest degree of compatibility for active PFC (power factor corrected) servers and sensitive electronics.
- SmartSlot - Customises UPS capabilities with network management cards.
- Scalable Runtime - Allows additional runtime as needed via external battery packs.
- Power Conditioning - Protects connected loads from surges, spikes, lightning and other power disturbances.
- Adjustable Voltage Transfer Points - Maximise useful battery life by widening the input voltage window or tightening the output voltage regulation.
- Temperature-Compensated Battery Charging - Prolongs battery life by regulating the charge voltage according to battery temperature.
- Intelligent Battery Management - Maximises battery performance, life, and reliability through intelligent, precision charging.
- Predictive Failure Notifications - Provide early-warning fault analysis, ensuring proactive component replacement.
- Plug-and-Play External Batteries - Ensure clean, uninterrupted power when adding extra runtime to a UPS.
What power conditions will a UPS battery backup protect against?
Many power problems originate in the commercial power grid, which, with its thousands of miles of transmission lines, is subject to damage from weather variations such as hurricanes, lightning storms, snow, ice, and flooding, as well as equipment failure and traffic accidents.
