Staco Energy Products Co. added SNMP communications capabilities to its FirstLine three-phase uninterruptible power supply (UPS). These models, which are available for 10, 15 and 20-kVA applications, allow users to network this UPS with their manufacturing and management systems.  With SNMP capabilities, FirstLine offers web browser based visual readings, alarm notification, a 48-hour system history, as well as client shutdown software for the most popular operating systems. FirstLine is a true on-line, double-conversion UPS that provides computer grade power quality. Despite its small footprint and low weight, the FirstLine has a standard internal battery run-time of up to 30 minutes (with optional batteries for virtually unlimited run time).
