The Tripp Lite PDUMNH20HVAT 3.3/3.8kW Single-Phase 208/240V ATS/Monitored PDU provides remote power monitoring and enables redundant power for network devices with non-redundant power supply configurations. Ideal for data centers and server rooms, it mounts in 1U of space in EIA-standard 19-inch racks and features one L6-20R outlet—perfect for connecting a single device or a 0U 208/240V PDU with an L6-20P plug.

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 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).

Dual 10-foot input cords with L6-20P plugs connect to separate primary and secondary single-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.

Tripp Lite PDUMNH20HVAT 7.4kW Single-Phase 230V ATS/Monitored PDU Features,

Primary and Secondary Inputs for Power Redundancy

• Dual 10 ft. input cords with L6-20P plugs connect to separate primary and secondary single-phase power sources
• Provides remote power monitoring and enables redundant power for network devices with non-redundant power supply configurations
• Fault-tolerant, hot-swappable UPS protection when used with single UPS; fully redundant UPS protection when each cord is connected to separate UPS systems

Built-In IEC 309 32A Blue Outlet

• Connects a single device or indirectly powers equipment through a 0U 208/240V PDU with L6-20P input (sold separately)

Automatic Transfer Switching

• Built-in processor prevents switching if secondary source is unavailable or of lower quality than primary source
• 1–5 ms transfer time ensures uninterrupted operation of connected equipment
• Switches to secondary power source if primary source fails or becomes unstable
• Dynamic solid-state (TRIAC) automatic transfer switching

Multifunction Digital Display with LEDs
