Cost Considerations

  • You can uncover any hidden costs by doing a detailed analysis of all your costs. Some of the things to consider include:
  • Prices for UPS's depend on what type you're purchasing. For example, a single-station UPS, which provides five to 10 minutes of backup power, can cost between $100 to $200. A UPS with extended run time can cost from $800 to $2,000. An online UPS can cost up to 20 percent more for comparable sizes.
  • Consider the cost advantages of buying a UPS that comes loaded with a lot of features versus the cost of adding features to a less expensive model.
  • Determine if purchase price includes the installation, as well as any management software.

What information should you be prepared to give vendors?
To bid for your business, vendors will want to know as much as possible about your network environment. Be prepared to provide them with the following information:

  • Specific application, installation location - office, data center, or industrial.
  • Input/output voltage requirements and KVA rating.
  • Battery time desired.
  • Look at your load requirements. What equipment will the UPS support and how much power will it need to draw? You can find this information on equipment labels. Also examine the mission critical load priorities.
  • Obtain the aggregate electrical load by taking ammeter readings of electrical distribution boxes at peak operating times, from listings on electrical distribution boxes, or as peak demand readings on your electrical bill.

What questions should you ask potential vendors?

  • What's the unit's time, and voltage range?
  • Does the unit include visual and audible alarms, and have battery capabilities?
  • Is noise filtering technology used?
  • Is the UPS compatible with power management software, as well as compatible with a UPS generator?
  • Do you have a battery and preventative maintenance program?
  • Do you employ factor-training field service engineers?
  • Do you offer dedicated service?
  • Has the unit met IEEE 587 or IEC 664 test requirements for surge suppression?
  • Does the unit include a modem, a fax, and some type of network protection to safeguard against surges coming through phone lines or network data lines?
  • Will you repair or replace equipment damaged due to a UPS malfunction?
  • What are the specifics of your warranty and or extended warranty?
