Management Interface
The management interface for this PDU model is transitioning to a new technology platform. The new interface can be distinguished by a USB-A port (for EnviroSense2 modules) in place of the round ENVIROSENSE port. For managing the units containing the round port, Tripp Lite recommends using the PowerAlert Console Launcher rather than a web browser. This application enables local access of the PDU using a self-contained, compatible Java Runtime Environment version. The Console Launcher can be downloaded for free; click the above link or go to the Management Solutions / Utilities page. Units with the new interface work will with most current web browsers.
Overview
The PDUMNH20HVAT 3.3/3.8kW Single-Phase 208/240V Monitored Automatic Transfer Switch / ATS 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.
The built-in Java-free HTML5-based LX Platform network interface enables full remote access for PDU status monitoring and email notifications via secure web browser, SNMP, telnet or SSH. It supports 10/100 Mbps auto-sensing for optimum communication with an Ethernet network. Optional EnviroSense2 modules (sold separate) provide a variety of environmental monitoring capabilities, including temperature and humidity conditions. Protocols supported include IPv4, IPv6, HTTP, HTTPS, SMTP, SNMPv1, SNMPv2, SNMPv3, telnet, SSH, FTP, DHCP and NTP. DHCP/Manual configuration lets you assign network settings to the card automatically, reducing the need for manual configuration. Automated alerts help prevent accidental overloads, power loss and downtime.
Features
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
- LX Platform interface allows full remote access for power monitoring with email notifications via secure web browser, SNMP, telnet or SSH
- Real-time load/current data with billing-grade accuracy (+/- 1 percent)
- Automated alerts help prevent overloads, power loss and downtime
- Optional EnviroSense2 modules (sold separately) provide a variety of environmental monitoring capabilities
Broad Communications Compatibility
- 10/100 Mbps auto-sensing allows optimal communication with 10/100 Base-T networks
Mounts Horizontally in 1U of Rack Space
