Liebert MPH

Liebert MPH is a flexible rack power distribution unit (PDU); a perfect solution for growing IT operations. This PDU offers data center power control to the receptacle level, as well as monitoring of the strip and environmental input options, such as rack temperature and humidity. Liebert MPH offers the industry’s leading operating temperatures, ensuring availability even in the harsh environment at the back of the rack.  Liebert MPH offers multiple power input selection and output configurations. Liebert MPH offers 1-phase 120 or 208VAC and 3-phase 120/208VAC 20 or 30 amp input power; 1-phase output power including mixed receptacles; and modular card-based communications. Liebert MPX is deployed in a vertical (Zero U) or rackmount configuration. Up to four Liebert MPH PDUs may be interconnected as a rack PDU Array, consolidating user IP connections and device monitoring.
Liebert MPH Monitored (MPH-NB) – Monitoring only version – provides local and remote monitoring of individual PDU volts, amps, watts, and kilowatt-hours.
Liebert MPH Monitored and Controlled (MPH-NC) – Monitoring and controlled version – provides the same features and functionality as the MPH-NB series with the additional capability of remote on/off control of individual receptacles. Local receptacle power on-off status is provided through an LED display.

  • The display is easily located to suit a crowded and changing rack environment.
  • Provides a compatible monitoring platform for Liebert MPH and Liebert MPX, offering seamless common operation if deployed together.

Higher Availability

  • Industry’s highest standard operating temperature (131F, 55C)ensures operation under high heat density conditions.
  • Controls and manages individual receptacles
  • Predicts overcurrent conditions before they become critical.
  • Allows user to shut down non-essential equipment during power outages to maximize availability and back-up power.
  • Expanded branch overload protection minimizes threat of cascading PDU overload.
  • Provides metering accuracy to +/-1%, improving operational oversite and user management of connected loads.
  • Optional temperature and humidity sensors allow oversight of environmental conditions.

Lowest Total Cost of Ownership

  • Provides full featured monitoring and control in a cost effective package.
  • A Rack PDU Array shares a single IP address for up to four Rack PDUs, making deployment faster and easier.
  • Energy and power metering provides users the information to maximize the data center power and cooling infrastructure.
