Energy Management System Upgrade Kit

Overview:

Millions of dollars a year are invested in power protection systems such as UPSs and generators, but problems can still occur at the branch circuit level due to improper loading or inadequate monitoring. You might not be able to see trouble coming until a circuit breaker trips, and that's too late. Systems go down. Valuable data is lost, and business comes to a standstill. It can take hours to recover.

The Energy Management System continuously measures the current on all breaker levels and warns you of impending trouble, so you can take proactive steps. Armed with these insights, data center and facility managers can more effectively balance loads, prevent overload conditions, plan for future capacity needs and, where applicable, allocate energy cost among internal departments.

Extending the reach of the EMS

The EMS has always integrated with Eaton's latest generation of power distribution racks, power distribution units and remote power panels. Now a new Eaton EMS Upgrade Kit is available to extend these branch circuit monitoring capabilities to existing equipment, from Eaton or other vendors.

With the EMS Upgrade Kit, you bring the entire power distribution system under the support of the EMS. Even if you have a mix of older equipment from other vendors, you get the insights to effectively manage the edge of the power distribution system. You will be able to track and analyze:

  • Time-stamped metering, alarm, event and statistical information
  • Peak loads, along with current, power and frequency minimums and maximums
  • Voltage and power, monitored all the way down to the branch breaker level
  • Power quality metrics, such as total harmonic distortion (THD) and power factor (PF)
  • Load profiling to make the best decisions for energy planning

This information is shown for individual circuits, each panelboard and at the equipment level—equipment such as a power distribution unit (PDU) or remote power panel (RPP)—to provide visibility at all levels in one system.

Feature list

  • Extends the branch circuit monitoring capabilities of the Eaton® Energy Management System (EMS) to legacy and third-party power distribution equipment
  • Monitors power conditions on individual breakers, panels or at the equipment level—three tiers of visibility within one unit
  • Provides remote monitoring via the Power Xpert® Gateway Card, which links Eaton and non-Eaton equipment to the local area network or the Internet
  • Tracks and records more energy parameters and provides more standard features than alternative branch circuit monitoring systems from other vendors
  • Delivers real-time and historical information for precision analysis, troubleshooting, power management, billing and energy planning
  • Streamlines and unifies the management of diverse, multi-vendor power distribution systems

Features:

A practical, affordable solution for precision power management

The EMS Upgrade Kit includes an enclosure that can be mounted on existing power distribution equipment or on a wall with the provided mounting kit. The enclosure supports one or two panels and an optional LCD. A single-panel unit monitors up to 42 circuits; a two-panel unit monitors up to 84 circuits in a standard, three-phase panelboard. Current transformers (CTs) monitor branch circuits in connected panelboards—measuring and storing energy parameters for each individual circuit—so you can manage power with greater precision.

Easy to deploy and use

The EMS Upgrade Kit is a packaged, pre-tested, standalone solution. It is designed for upgrade into existing Eaton and third party PDUs, RPPs, panelboards or other equipment. The unit comes with its own bracket for wall-mounting and can be installed without disconnecting the branch circuit wiring to the loads. An easy-to-use software tool is included to configure start-up settings and options. No preventive maintenance or annual calibration is required. You gain new insight into power distribution without adding complexity to the infrastructure.

Visibility and control from anywhere

A Power Xpert Gateway Card installed in an X-Slot® communication bay enables remote monitoring over an Ethernet network. You can view detailed power parameters using a Web browser, an SNMP-compatible network management system or a Modbus TCPcompatible building management system. The system can even be configured to e-mail event notifications when alarm conditions arise.

Important power information at a glance

A large, local LCD—eight lines by 40 characters (many times larger than competitors' offerings)—is a popular option. This display delivers a rich array of information about status, events and alarms at any level. Navigate easily through system functions using buttons and contextual menus that are organized into logical categories.

  • Temperature and humidity monitoring with the optional Eaton Environmental Monitoring Probe (EMP)

Cost-effective insurance against tripped circuits and unplanned shutdowns

Branch circuit monitoring technology has been field-proven for years. Recent advances in technology and design have made these capabilities more affordable than ever. When comparing features and technical specifications of different systems, you will quickly see that the EMS provides more all-in-one functionality than other vendors' offerings. It has the most standard features and the broadest list of measured and reported parameters.

With the EMS Upgrade Kit, now you can extend this extra layer of visibility and control to distribution equipment that was never designed to include those capabilities.
