High-capacity 3.3/3.8kW PDU with ATS provides remote power monitoring and enables redundant power for non-redundant hardware. Digital display and Ethernet interface monitor load levels to prevent overloads that cause downtime.

- Two single-phase L6-20P inputs with 10 ft. cords
- L6-20R outlet for connecting single device or 0U vertical PDU
- Automatic transfer switching within 1–5 ms
- Ethernet network interface for remote access
- Digital display for real-time status monitoring

The 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.

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.

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).

Primary and Secondary Inputs for Power Redundancy
- Provides remote power monitoring and enables redundant power for network devices with non-redundant power supply configurations
- Dual 10 ft. input cords with L6-20P plugs connect to separate primary and secondary single-phase power sources
- 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 L6-20R Outlet
Connects a single device or indirectly powers equipment through a 0U 208/240V PDU with L6-20P input (sold separately)

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

Multifunction Digital Display
- Reports source A and source B input power status and other information, including power availability, line voltage, frequency, amps, kilowatts and power factor

Advanced Network Monitoring
- Built-in Ethernet network interface allows full remote access for power monitoring, configuration, control and notifications via web browser, SSH, telnet or SNMP
- Real-time load/current data with billing-grade accuracy (+/- 1 percent)
- Automated alerts help prevent overloads, power loss and downtime
- Optional ENVIROSENSE module (sold separately) monitors temperature and humidity

Broad Communications Compatibility
- Supports HTTP, HTTPS, PowerAlert®, SMTP, SNMPv1, SNMPv2, SNMPv3, Telnet, SSH, FTP, DHCP, BOOTP and NTP
- 10/100 Mbps auto-sensing allows optimal communication with 10/100 Base-T networks

Mounts Horizontally in 1U of Rack Space
- Compatible with EIA-standard 19 in. 4-post racks and rack enclosures
- Optional PDU4PKIT rail kit (sold separately) adds rear mounting support
