The DM2000 Power Systems Digital Monitor is a rack-mounted, µP-based power management system that controls, tests and monitors critical operations of redundant power equipment. The unit allows automatic or manual battery testing with capacity and time-to-run predictions, offers user configurable alarm settings, and is fully password protected, building a history log that indicates the time, date and nature of the last 40 fault events. It also offers temperature-compensated float voltage control. The unit can export data in a common delimited file format for easy integration into a network management system. Access is accomplished by use of unit's LCD, by an RS-232 link to a local PC, or through a remote dedicated network connection.
