Get ultimate control over your power with SentryHD

(not available for the EN450G model)

In today’s complex world of data, networks, and software, control and management of applications is vital, especially when it comes to the power that is supplied to these devices.

SentryHD, included free with all current Minuteman UPS systems, is the latest update to Minuteman’s popular Sentry monitoring and management software. This powerful tool provides users and network managers with a range of monitoring & management tools for their power, allowing total control before, during, and after power problems.

With a simple connection to the UPS via USB or RS-232, SentryHD provides the capability to configure UPSs, monitor power, and diagnose issues, all from secure connections on the network. This eliminates wasteful runs around the facility, saving time and money.


5 Full Years of Trouble-free Service – Guaranteed

Minuteman UPSs already ship with the best warranty in the business at 3 years, including non-prorated battery coverage on most products.

Two levels of Extended Warranty Plans are also available on most UPS product lines to provide an additional 2 years of coverage. These plans ensure a full 5 years of trouble-free ownership.
