The PRO1500RT is a value-priced, yet feature-rich UPS incorporating line-interactive technology that preserves battery power by providing Automatic Voltage Regulation (AVR) during brownouts or voltage sags. The PRO1500RT can be used to support servers, telecom or VoIP systems, security systems, plus many other applications. An LCD display provides visual notification of power status, including input voltage, frequency, percent of battery charge, estimated runtime, plus many other conditions. Each PRO-RT model includes Minuteman's SentryPlus(tm) power management and diagnostic software. When installed on a workstation or server, the user gains complete control over monitoring and managing the UPS using a convenient web browser interface. The SentryPlus software communicates via a built-in USB port or through a RS-232 connector on the UPS. In addition, managing the UPS within a Network Management System (NMS) is easy with the installation of an optional SNMP card. Designed for versatility, the PRO1500RT can be mounted in a standard rack using the included rackmount ears. These ears can also be attached to the unit to allow it to stand as a tower. An optional kit is available for mounting the unit to a wall.
