Uninterruptible Power Supplies (UPS) - Three Phase

Monitored Distribution Units

MDU Series: Model MDU-CL

 

Providing Critical Power Distribution within the Datacenter
The MDU-CL Monitored Distribution Unit provides a flexible design to provide power distribution to critical loads. Each unit can be configured to provide isolation, voltage transformation, harmonic reduction and voltage regulation. Up to 252 poles of distribution can be incorporated within the MDU.Each unit internally uses GE Panelboards and Circuit Breakers.

The MDU-CL can also provide needed branch circuit monitoring to assist users in determining load balancing over the three phases, plus provide alarm set points to insure the load on all circuits does not increase to a point that could trip the unit's main circuit breaker.

Features:

  • Top or Bottom Cable Entry ; Front Access only needed
  • Side-Facing and Front-Facing Sidecars for extra branch circuits
  • Datacenter Raised Floor or Concrete Floor mounting
  • Copper Wound
  • K20 Rating Standard
  • TP1 High Efficiency design
  • Patented design to monitor all poles of distribution
  • Local and/or Remote Monitoring of circuits
  • Available as Retrofit Kit on existing PDUs
  • Transient Surge Network
  • Lightning Arrestor
  • Subfeed CBs in lieu of or in addition to Panelboards
  • Datacenter Floor Support Stands

MDU Series: Model MDU-HP

 

Providing Critical Power Distribution to the Datacenter
The GE Series MDU-HP Monitored Distribution Unit provides a flexible design to provide three phase power to other distribution units and/or overhead busway. Each unit can be configured to provide isolation, voltage transformation, & voltage regulation. Up to (14) Subfeed CBs can be incorporated within the MDU-HP. Each unit internally uses GE Panelboards and Circuit Breakers.

The MDU-HP can also provide subfeed CB monitoring to assist end users in determining branch circuit and total load to prevent overloading of the MDU Main CB.

Features:

  • Top or Bottom Cable Entry ; Front Access only needed
  • High Power Density in small footprint
  • Typically Concrete Floor mounting
  • Copper Wound
  • K20 Rating Standard
  • TP1 High Efficiency design
  • Patented design to monitor Subfeed CBs
  • Local and/or Remote Monitoring of circuits
  • Remote monitoring via RS485 Modbus or optional SNMP
  • Transient Surge Network
  • Dual Input
  • Low Inrush Transformer
  • IR Scan Windows

Remote Distribution Units

RDU Series: Model RDU-CL, RDU-MC, RDU-SC, RDU-WM

 

Providing Critical Power Distribution to the Datacenter
The GE Series RDU Remote Distribution Unit provides a flexible design to provide an extension of power distribution circuits to critical loads. Each unit internally uses GE Panelboards and Circuit Breakers.

The RDU can also provide needed branch circuit monitoring to assist users in determining load balancing over the three phases, using alarm set points to insure the load on all circuits does not increase to a point that could trip the RDU's main circuit breaker.

Distributed Power Busway

DPB Series: Distributed Power Busway

 

Providing Critical Power Overhead Distribution to the Datacenter
The GE Series DPB Busway is a flexible design specific to datacenter applications, that provides overhead power distribution via three phase Bus Rails and Tap-Off Boxes to critical loads. The Tap-Off Boxes utilize GE Circuit Breakers.

The DPB Busway design is estimated to save 60% in time and labor than traditional conduit and wire installations. This product also aligns with an industry trend whereby many datacenters are now concrete floor construction, thus making overhead power distribution cost effective.

Features include:

  • Compact, safe construction
  • Class H Insulation
  • Nickel-Plated Copper Bus Bars
  • 3, 5, 6, 10, 12ft Bus Rail Sections available
  • Integral Ground Path
  • 22 − 42 KAIC rated
  • Simple Tap-Off Box installation ; no 90 degr turn req'd
  • Branch Circuit Monitoring (BCMS) available
  • BCMS Hub to monitor all branch circuits
