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


Benefits

●Establish “green” image and qualify for LEED ratings

●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

●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


Measurement parameters

● 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

The PowerLogic EM4800 meter provides the information that building owners need to bill tenants, manage energy use and reduce their overall costs.


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.

The PowerLogic EM4800 provides highly accurate energy information so that building owners can bill tenants for their actual energy use.

Installation options

Embedded applicationWall Mount application

PowerLogic EM4800 meters are ideal for both retrofit and new installations.

PowerLogic EM4800

● 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


Physical characteristics

Rugged enclosure for either wall mount or installation within a power distribution panel. Suitable for both indoor and enclosed outdoor applications.

LCD backlit display, with optional remote display

Standard Ethernet port and onboard modem enable fast and easy integration into existing networks

Two digital pulse inputs to accumulate information from WAGES meters

Voltage sense inputs allow a wide input range: 100 Vac to 300 Vac L-N

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

Onboard memory collects up to two years of energy use data, while the clock ensures accurate time-stamping

Web server allows connection through your browser


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 1: Configure as 24 single-phase, one-CT meters

Option 2: Configure as 12 single-phase, two-CT meters

Option 3: Configure as 8 three-phase, three-CT meters

Select the loads to meter - even if they are in different power distribution panels. Note: the panels must share a common voltage reference

Example meter point: CTs installed adjacent to a 3-phase circuit breaker; 8 meter points shown in diagram.

PowerLogic EM4800 series meter overviewThe 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:

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

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 or EM4880

Lead lengths up to 100 m (325 feet) for 1/3 V and 80 mA CTs!

Electrical Room #1

Electrical Room #2

Three-phase meter point with 80 mA or 1/3 V CTs. A total of 8 three phase meter points are shown.

Conduit used to connect CT leads to EM4800 meter. All CT leads are up to 100 m (325 feet) in total length

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!

EM4880 or EM4833 meter, installed outside of Electrical Room, allowing easy access

The EM4800 can even monitor panels on different floors within the building Note: the panels must share a common voltage reference

Installation example: EM4880 or EM4833

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
