Product resources


Designed for:
  • PCs
  • Telephone Systems
  • Data Communications


  • The built-in double-boost and single-buck AVR (Automatic Voltage Regulator) function compensates for broader range of low AC voltage situations like brownouts and sags as well as high AC voltage situations like surges and spikes saving internal battery power for blackouts and extending the life of the batteries
  • Independent Battery Bypass™ allows the UPS to provide voltage regulation with surge and spike protection on utility AC power even when batteries are weak or dead
  • Includes MINUTEMAN SentryII™ power management and diagnostic software to provide added control and allow unattended PC shutdown (for use on individual PCs or multiple workstations on networks)
  • Integrated USB and RS232 ports for software communications (USB and RS232 cables included)
  • 3-Year Parts and Labor Warranty
  • $50,000 MINUTEMAN Platinum Protection Plan® (U.S. and Canada)

High-quality protection with a compact design
The MINUTEMAN® PRO-E™ Series of Uninterruptible Power Supplies (UPS) delivers complete protection from electrical problems — spikes, surges, sags, brownouts, and blackouts. All PRO-E models are amazingly compact and take up little space on the desktop or under a console. The PRO500E and PRO700E units provide an ample power source for a computer, monitor, and other attached devices with four (4) battery backup outlets with surge protection and two (2) surge-only outlets. The PRO1100E and PRO1500E models are only slightly larger in physical size, yet each offers an expansive six (6) outlets with battery backup and surge protection and heavy power-handling capabilities found in much larger-sized models. This size-to-power ratio makes them ideal for high-power requirement devices installed in cramped quarters.

"E" for enhanced features
Each PRO-E model has enhanced features from its predecessors like built-in Automatic Voltage Regulation (AVR) technology to provide a double-boost to incoming AC during low voltage situations in addition to “bucking” or trimming the AC during a high voltage situation, preserving vital battery backup power for blackouts, and extending the life of the batteries. Unlike some competitive models, the PRO-E model includes Independent Battery Bypass™ which allows it to provide AVR and surge and spike protection with weak or even dead batteries without dropping the load from utility AC power. Other features include adjustable input and output voltage ranges for AC mode and on-battery voltage can also be set to a steady 120 or 127 volts via dip switches on the back of each PRO-E model. Each unit also includes protection for either a network or a phone line to keep damaging AC surges and spikes from entering through those pathways (network protection only on 230 volt models).

Reliability — Guaranteed
MINUTEMAN PRO-E™ units are backed by an unprecedented 3-year warranty that covers all parts and labor. The MINUTEMAN Platinum Protection Plan® insures properly connected equipment for up to $50,000.

SentryPlus Software

Powerful SentryPlus UPS Monitoring and Control Software Minuteman’s SentryPlus™ UPS monitoring and control software comes included with each Endeavor UPS unit at no extra charge. SentryPlus is compatible with Windows (XP, 2000, Server 2003, NT 4.0, ME and 98), Unix and Linux operating systems. With SentryPlus software users can monitor and control any new and previously sold or installed Minuteman UPS products on a connected network from one application session. The ease of installation, ease of use, and backward compatibility makes it the best software of its kind.
