Entrust Series Overview

Big features, small price

The Minuteman Entrust Series UPS provides users all the features usually available in higher-priced UPS products to protect your valuable equipment: automatic voltage regulation, spike and surge protection, and battery backup.

Each unit has four outlets that provide battery support along with spike and surge protection. There are an additional four spike and surge protected outlets for accessory devices that dont require battery support. There are even two outlets that are specifically spaced to support transformer block items.

The ultra-slim footprint of the Entrust UPS is ideal for placement on, or under, a desk. Slim profile allows for installation vertically in tight spaces, including cabinets and rack shelves.

Additionally, Entrust products come with all the award-winning service and support capabilities offered by Para Systems, Inc. including a three-year warranty, (two-years on the battery), and a $75,000 Platinum Protection Plan.
