The PDU330AT6L2130 8.6kW 3-Phase 208V ATS/Monitored PDU provides remote power monitoring and enables redundant power for network devices with non-redundant power supply configurations. Working in tandem with a required 0U vertical outlet accessory (sold separately; choose from PDU3VD351, PDU3V20D354, PDU3V20D354A or PDU3V20D354B), the 1U PDU330AT6L2130 is ideal for data centers and server rooms. Dual 6-foot input cords with L21-30P plugs connect to separate primary and secondary 3-phase power sources. The PDU constantly evaluates the power quality of both input sources. Dynamic solid-state (TRIAC) automatic transfer switching allows the PDU to switch to the secondary source within 1 - 5 milliseconds should the primary source fail or become unstable to ensure your connected equipment operates without interruption. Built-in Ethernet network interface allows remote access to the PDU for power monitoring, configuration, control and notifications via web browser, SSH, telnet or SNMP. Provides real-time load/current data with billing-grade accuracy (+/- 1 percent). Tiered access privileges allow both an administrator and a guest to log in. Automated alerts help prevent accidental overloads, power loss and downtime. Digital LED display indicates power availability, voltage, source A/B input status, output load and power factor, as well as temperature and humidity conditions with the optional ENVIROSENSE module (sold separately).
