Marketing features
Peace of mind that comes with full equipment compatibility and reliability of a leader
Provides pure sine wave output which is recommended by server manufacturers using active power factor corrected (PFC) power supplies. Safety agency tested and approved means that you can deploy Smart-UPS with confidence that they meet or exceed the industry’s most rigorous standards.

Save time with easy and convenient remote/network accessibility.
Network manageable via serial, USB or Ethernet. Includes Powerchute® Software for convenient monitoring and control, safe operating system shutdown, and innovative energy management capabilities.

Avoids costly power problems by keeping your IT equipment and data protected and available.
Network grade power conditioning protects from damaging surges and disruptive noise. The double conversion architecture provides tight voltage regulation, frequency regulation , and zero transfer time to battery during power events.

Low operating and maintenance costs with proven reliability and intelligent battery management.
Intelligent battery management, pioneered by APC, maximizes battery performance and life through intelligent, precision temperature compensated charging. Automatic self tests insure battery reliability and warn customers in advance of battery replacement. Convenient, easy to connect, hot-swappable battery modules provide battery replacement without powering down.

Adaptability
Flash upgradeable firmware
Install maintenance releases of firmware remotely using FTP.

Plug-and-Play external batteries
Ensures clean, uninterrupted power to the loads when adding extra runtime to the UPS.

Rack/Tower convertible
Protects the initial investment in the UPS when migrating from tower to rack-mount environment.

Protection
Cold-start capable
Provides temporary battery power when the utility power is out.

Resettable circuit breaker
Easy recovery from overloads; no need to replace a fuse. (Not available on Wall Tap SKUs)

Safety-agency approved
Ensures the product has been tested and approved to work safely with the connected service provider equipment and within the specified environment.

Input Power Factor Correction
Minimizes installation costs by enabling the use of smaller generators and cabling.

Power conditioning
