  1. PowerLogic EM4800multi-circuit energy meter Simple, accurate tenant sub-metering

  2. The PowerLogic EM4800 series meters provide simple, reliable, revenue-grade electricity metering. • High density multi-circuit meter: connections for 24 CTs • Billing-grade accuracy: ANSI C12.20 Class 0.5 & IEC 62053-22 Class 0.5S • Wide-range voltage-sensing inputs: 100 to 300 V ac • Direct connect to: 120/240 V, 120/208 V, 230/240 V, 220/380 V, 240/415 V, 277/480 V • Low cost per meter point • Flexible installation options: ideal for both new construction and retrofit projects • Multiple communication options: Ethernet, modem, onboard web server • Onboard memory with industry standard protocols – Modbus TCP, FTP – providing easy integration into monitoring software • Rugged enclosure and maintenance-free design Optional Remote Display PowerLogic EM4800

  3. Applications Ideal for multi-tenant and departmental metering applications in commercial buildings: • Office towers • Condominiums • Apartment buildings • Shopping centers • University dormitories and apartments • Other multi-user environments

  4. Benefits • Bill tenants accurately for energy use • Encourage tenants to manage energy consumption • Manage energy use to reduce operational costs and offer more competitive lease rates • Establish “green” image and qualify for LEED ratings • Allocate costs to departments or processes to expose wasteful energy practices • Identify the source of peak demand charges • Identify saving opportunities within your facilities • Verify utility charges using accurate meters

  5. Measurement parameters The PowerLogic EM4800 meter provides the information that building owners need to bill tenants, manage energy use and reduce their overall costs. • Real energy, delivered and received (kWh)* • Reactive energy, delivered and received (KVARh)* • Apparent energy (kVAh)* • Real power (kW) • Reactive power (kVAR) • Apparent power (kVA) • Voltage* and current (per phase) • Power factor • Pulse counts* • Measurements available for data logging

  6. High accuracy, multi-tenant metering Use the EM4800 to meter every tenant, as well as shared-use loads, within a commercial building. A single EM4800 can meter 24 single phase circuits or 8 three-phase circuits. EM4800 The PowerLogic EM4800 provides highly accurate energy information so that building owners can bill tenants for their actual energy use.

  7. Installation options PowerLogic EM4800 meters are ideal for both retrofit and new installations. • Flexible installation options allow the product to be effectively used in virtually any commercial building that requires highly accurate and cost effective energy metering • The rugged enclosure allows the meter to be either wall mounted, or embedded within a power distribution panel Wall Mount application Embedded application PowerLogic EM4800

  8. Physical characteristics LCD backlit display, with optional remote display Voltage sense inputs allow a wide input range: 100 Vac to 300 Vac L-N Standard Ethernet port and onboard modem enable fast and easy integration into existing networks • Connection points for 24 current transformers (CTs). • Configure each EM4800 to match your needs: • 24 single CT meter points • 12 two CT meter points • 8 three CT meter points Two digital pulse inputs to accumulate information from WAGES meters Onboard memory collects up to two years of energy use data, while the clock ensures accurate time-stamping Rugged enclosure for either wall mount or installation within a power distribution panel. Suitable for both indoor and enclosed outdoor applications. Web server allows connection through your browser

  9. Flexible configuration PowerLogic EM4800 multi-circuit meters can be configured to match the power distribution panel that you are monitoring: configuration is user-selected andcan change as often as required. Option 2: Configure as 12 single-phase, two-CT meters Option 3: Configure as 8 three-phase, three-CT meters Option 1: Configure as 24 single-phase, one-CT meters Each meter point can be assigned to a tenant or department

  10. Low cost per meter point Power distribution panel #1 Power distribution panel #2 A single PowerLogic EM4800 multi-circuit meter can replace up to 8 three-phase power meters, resulting in significant cost savings.

  11. PowerLogic EM4800 series meter overview The meters are available in three models. Measured values, communication options, features and software support are consistent for all three models. Select the model that you need for your specific project: EM4880 - Uses 80 mA output CTs Used for new installations • Solid core, 200 A primary CT available • Extra long leads supported – up to 100 m (325 feet) • Shorting blocks recommended • Enclosure size: 33.5 cm x 30.5 cm x 5.5 cm 13.125 in x 12 in x 2.125 in EM4805 - Uses 5 A output CTs Used for retrofits and new installations • Industry standard CTs - available in a wide range of sizes • Solid core and split core CTs available • Shorting blocks required • Enclosure size: 33.5 cm x 44 cm x 5.5 cm 13.125 in x 17 in x 2.125 in EM4833 - Uses 1/3 V output CTs The best solution for retrofit projects • Solid core and split core CTs available • Extra long leads supported – up to 100 m (325 feet) • Shorting blocks not required • Enclosure size: 33.5 cm x 30.5 cm x 5.5 cm 13.125 in x 12 in x 2.125 in EM4833 or EM4880 Lead lengths up to 100 m (325 feet) for 1/3 V and 80 mA CTs!

  12. Installation example: EM4880 or EM4833 Commercial building floor plan Previously, building owners with dispersed loads would need to install energy meters throughout their facility – but the EM4800 provides a simpler solution: 80 mA and 1/3 V CTs support extra long lead lengths of up to 100 m (325 feet) – you can monitor loads throughout your facility with a single EM4800 meter! Electrical Room #1 EM4880 or EM4833 meter, installed outside of Electrical Room, allowing easy access Three-phase meter point with 80 mA or 1/3 V CTs. A total of 8 three phase meter points are shown. Electrical Room #2 The EM4800 can even monitor panels on different floors within the building Note: the panels must share a common voltage reference Conduit used to connect CT leads to EM4800 meter. All CT leads are up to 100 m (325 feet) in total length

  13. Flexible communications The EM4800 comes standard with both an Ethernet port and a modem so that you can quickly connect to the meter over your existing communication network Industry standard protocols ensure that you can easily integrate the energy data from the EM4800 into your tenant billing or energy management software • Ethernet port • Modbus TCP • FTP • HTTP (Webserver) • SNTP (time sych) EM4800 • Modem • FTP • SNTP (time sych) The EM4800 is fully supported in Schneider Electric software: ION Enterprise* and Remote Energy Monitoring (REM) *Available: September, 2011

  14. Pulse inputs for WAGES metering Two digital pulse inputs accumulate readings from WAGES meters to give you a complete view of your overall energy use.
