About American Power Conversion (APC)

The APC Back-UPS 500 6-Outlet Backup and Surge Protector (120V, Black) provides professional power protection and battery backup for computer systems. Safe system shutdown and advanced power management capabilities keep systems and data safe via serial or USB connection and built-in phone/fax/modem (DSL-compatible) connections protect systems from surges traveling on data lines. The UPS features 6 outlets, 3 of which provide battery backup and three more that are surge protected. The unit delivers battery-powered AC and its battery provides 15.4 minutes of run time at half-load capacity.

American Power Conversion (APC) Features

  • Data Line Protection: The surge protector features an RJ-11 surge protection connection that allows you to protect modem connections from power surges. This helps to preserve the life of your modem and further protect your computer from surges
  • Spaced Outlets: The UPS features two spaced outlets that are designed to accommodate devices with large "power brick" AC adapters. This lets you power and protect these devices without sacrificing another plug due to their large size
  • Audible Alarms: The surge protector features an audible alarm that lets you know when there is a problem with your power. This helps to make you aware of a power outage or surge
  • Serial Communication: This UPS features serial ports for computer communication. This communication allows your computer to automatically shut down safely in the event of a power outage
  • Battery Failure Notification: Provides early-warning fault analysis on batteries enabling timely preventive maintenance
  • LED Indicators: Provide easy-to-read status of the unit and utility power conditions
  • Battery-Protected and Surge-Only Outlets: Reserves power capacity and run time for connected equipment that require battery back-up while providing surge only protection for less critical equipment
  • Cold-Start / Hot Swap Batteries: Cold-start capable provides temporary battery power when the utility power is out. Hot-swappable batteries ensures clean, uninterrupted power to protected equipment while batteries are being replaced
  • Disconnected Battery Notification: Warns when a battery is not available to provide backup power
  • Automatic Self-Test: Periodic battery self-test ensures early detection of a battery that needs to be replaced
  • User-Replaceable Batteries: Increases availability by allowing a trained user to perform upgrades and replacements of the batteries reducing Mean Time to Repair (MTTR)
  • Intelligent Battery Management: Maximizes battery performance, life and reliability through intelligent, precision charging
  • 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
  • Battery Replacement Without Tools: Allows quick, easy battery replacement

Once Again!

Once again, this product is just what I need! Replacing the old one was simple, and the fact that I could recycle the old one so easily was wonderful! Thank you!

APC UPS units are very reliable, work 100% of the time for us. I prefer to buy the units with the outlets on the back. The UPS's that have the plugs on top have had debris including spent staples fall into the outlets. My only gripe is that APC no longer uses right angle plugs on the power cord. In a busy environment like ours it is common to find the plugs on the UPS hanging half out of the wall outlet resulting in a poor connection. The older style right angle plugs never came loose.

Excellent UPS


from Nebraska

This is a nice compact unit. I like having the outlets on the back of the unit. One of my UPS units has the outlets on the top and they get dusty. I will replace it with one of these when the battery fails.


Trust No Other


from Silicon Valley, CA

I have used APC Back-UPS for over 10 years with various home computers. The batteries do need to be changed at some point around 3-4 years. APC is up front about this. My current Back-UPS CS 500 sits next to my Dell Inspiron quad PC, filters line problems, self-tests, powers after commercial power is removed, and even shuts down my PC gracefully via supplied USP cable according to the params that I set. A PC application lets you initiate a test, review the test log, review power levels and more. It's well worth the price to protect an expensive PC like the one I use.


APC backs up their back ups!


from Florida

Had and issue with run time with the first unit I recieved. Called APC service and within 10 min I had a tracking # and p/u tag for the old one. Received the replacement in 4 days. What can I say...APC backs up their back ups! I have found that this product does what it specs out to do! Only issue I have is that the cooling fan is a bit noisy, but the good thing it doesn't stay on for long.


Latest in a long line


from Atlanta, GA

This is my 5th APC UPS. The last one stopped working after 10 years of dependable service. Nothing to do but replace it with something I know I can depend on.


great purchase


from Sarasota, FL

Easy to install, works without a problem. I always order from APC because I can depend on the quality.


Completely reliable, great product


from Dallas, TX

I've been working with this Back-up for a little while now, and my experience has been consistently excellent. As with other APC products I have owned, the craftsmanship is very high-quality and it gives me a high degree of confidence in the product.


Best equipment.


from West Middlesex, PA

I have been using APC products for 16 years. They have never let me down and even when they are outdated. Easy to in stall and manage. I wish more products where built with the same time, concern, and quality as APC.
