I can get my normal brand of UPS shipped very quickly. How quickly can Liebert deliver?

Liebert maintains a warehouse of products for quick distribution. Ingram Micro and Tech Data also stock many standard Liebert UPS products for next day shipment.

I’ve been using APC SmartUPS lineinteractive technology for years, so why use Liebert’s PowerSure PSI systems now?

The Liebert PowerSure PSI offers significant advantages over the SmartUPS system and other line-interactive systems. Advantages include:

  • Lower price when ordered network-enabled.
  • Network enabled on delivery, with the Liebert IntelliSlotWeb Card factory installed.
  • Extended battery option on same unit, so you don’t have to upgrade to another UPS to add battery cabinets as you do with the APC SmartUPS.
  • Delivered fully assembled — batteries connected and activated at the factory.
  • Two-year, no hassle replacement warranty, in which we replace the unit usually in 24 hours — and pay shipping both ways.

Why don’t your units come out best in our specification for this product?

Make sure the specification is an apples-to-apples comparison. If it is, the sale may be a long shot. If it’s not, determine whether the specification is accidental or deliberate (that is, a specification written to allow only one product to survive a competitive process). Offer to prepare a true apples-to-apples comparison to include the level of power protection required; maintenance, service and warranty considerations; and price.
