Liebert MPX provides for scalable global power distribution by means of compatibility with a wide variety of North/Central American, European, and International power supply cords, connectors, and receptacles/sockets. Liebert MPX Adaptive Rack PDU system delivers break-through flexibility, availability and total cost of ownership. Liebert MPX enables users to respond to and manage changing rack power and management environments. Liebert MPX provides users the ability to size their Rack PDU system to support initial requirements and then adapt as connectivity, capacity and/or functionality needs change. Liebert MPX is based on a patent pending design built on a power / communication bus and input/output power module strategy.
Liebert MPX is provided as separate ship-loose modules for user on-site configuration. Liebert MPX is designed for simple and quick configuration and reconfiguration. Pre-configured systems are available as an SFA when ordered as factory installed in Knurr rack enclosure systems. Liebert MPX design is modular in that the input power service and distribution means are segmented into functionally discrete components that are operatively fastened onto a common MPX Power Rail Chassis (PRC).
Liebert MPX monitors electrical attributes of an individual Rack PDU, including real-time remote and (optional) local display of monitoring of aggregate and branch electrical parameters (status, thresholds, alarms) including voltage, amps, kW, and kW-hr. Liebert MPX features include: Rack PDU and Branch load monitoring and control for continuous uptime and minimum disruptions; Expandable monitoring interface providing simplified growth management; rugged construction; offered factory installed in the Knurr rack enclosure system. Liebert MPX provides power-related metering of inputs and outputs. This information can be conveyed to other public network devices via a Rack PDU communications Card (RPC-1000) plug-in card inserted into the MPX PEM to gain direct access to the private, inter-module communication bus to which all modules are operably connected. Additionally, the RPC provides support for local environmental sensing and control, and RPC Basic Display Module (BDM), operatively coupled and intended for viewing to facilitate installation configuration and system troubleshooting.
The Liebert MPX is intended for use with light industrial, telecommunication, and network infrastructure and is designed for safety in accordance with the harmonized IEC 60950-1 1st Edition Information Technology Equipment Safety standards. The Liebert MPX is designed as Class I stationary equipment and will protect against electric shock by basic insulation with a bonded connection to the ground in the building installation wiring.
1.4. System Components
Liebert MPX Adaptive Rack PDU is composed of several key building blocks and support modules. Liebert MPX is built on the MPX Power Rail Chassis (MPX PRC) that distributes power and communications to all support modules, acts as a backplane to mount support modules, and offers provisions to physically mount the Liebert MPX in a network rack. Input power is connected and delivered to the Liebert MPX system via the MPX Power Entry Module (MPX PEM). Output power connectivity and communications management level is defined by the MPX Branch Receptacle Modules (MPX BRM). MPX BRM power connectivity includes NEMA, IEC and Schuko receptacles. MPX BRM capabilities include Branch Monitoring and Receptacle Management versions. Network communications, sensor and/or local display interface is provided by the Liebert Rack PDU Card (Liebert RPC) that mounts in the MPX PEM. The Liebert RPC provides connection to an optional RPC Basic Display Module (RPC BDM) for local status / alarm viewing. Two different module versions are available for North American and European applications. The following sections identify and describe the electrical performance requirements and their implementation strategies for each Liebert MPX component.
1.4.1 MPX Power Rail Chassis (PRC)
The MPX PRC distributes power and communications to the installed MPX modules. The MPX PRC supports single and three phase power input from 20 to 60amp (North America), 16 to 63 amps (European). It includes provisions to mount and secure input power (MPX PEM) and output receptacle (MPX BRM) modules. It is available in lengths to accommodate typical 23 or 42U network racks; 1035mm (40.75in) or 1880mm (74.0in). The MPX PRC includes zero-U mounting provisions that accommodate most rack designs. The MPX PRC is provided with cover / spacers to assist users with positioning for future MPX module.
1.4.2. MPX POWER ENTRY MODULE (PEM)
The MPX PEM provides input power to the MPX system and includes provisions for addition of the RPC (Rack PDU Card) to support remote and local communications. The MPX PEM is available in two versions: Variable Capacity and Fixed Capacity. The MPX PEM Variable Capacity version allows the user to select and change power input via different MPX IPC’s. The MPX IPC includes cord, MPX PEM connector, and input plug (NEMA or IEC). The MPX PEM Fixed Capacity version supports rated input capacities from 40 up to 63 amps with fixed cord and plug connections. All MPX PEMs include an audible overcurrent alarm with local reset. One MPX PEM is required per MPX Rack PDU.
The MPX PEM can be installed onto either end of the MPX PRC to energize it via a safe, secure, and reliable mating connection.
The MPX PEM does not support hot-swap capability and it must be first disconnected from the AC mains supply and the device loads must be disconnected from the MPX BRMs before it can be safely removed from the MPX PRC.
MPXPEM-NVAXXAXX: 120 or 208VAC single phase &/or 208-240VAC three phase input up to 30Amp.
The MPX PEM Variable Capacity version allows the user to select and change power input via different MPX IPC’s. The MPX IPC includes cord, MPX PEM connector, and input plug (NEMA or IEC). The MPX IPC is available in multiple versions supporting up to 30 amps including single phase North American 120VAC and 208VAC and three phase North American 120/208VAC connections.
