PowerLogic®
Submetering
PowerLogic Energy Meter
The Energy Meter is ideal for stand-alone and systems-based submetering applications. It is easy to install and provides exceptional metering accuracy. Available in Basic and Extended Range models. The Basic model is designed for metering of 120/240 and 208Y/120 volt services. The Extended Range model will meter 120/240 volt up to 480 volt Wye connected services. Extended Range meters come with pulse output and phase loss output not available on the Basic unit. Optional Modbus® RS-485 serial communications are provided with the Energy Meter Comms Board, EMCB. Optional kW demand is also provided by the EMCB.
Meter up to 3 individual services with one Energy Meter. The Energy Meter will allow the addition of up to 3 sets of parallel CTs for metering multiple electric loads. Additional sets of CTs can be ordered separately. Please refer to the multiple CT application notes in the Energy Meter instruction bulletin for the proper installation procedures.Energy Meter

a Energy Meter communication board (EMCB) can be used with all models of the Energy Meter. Order one EMCB for each Energy Meter where either kW demand and/or communication is specified.
PowerLogic Enercept® Meter
The Enercept Meter is the ideal solution for submetering electric loads where space is at a premium. The compact design consists of three interconnected split-core CTs with the metering and communication electronics built into the CT housing. Simply snap on the CTs, connect the voltage inputs, the communication lines, and installation is complete. Both versions can be connected to either three-phase or single-phase circuits.
Enercept meters employ the Modbus® RTU 2-wire communication protocol, and can utilize the same communication network and PowerLogic System Manager™ software as other PowerLogic devices. Data from the Enercept meters can be presented in tabular or graphical format, used for alarming and historical logging and trending, and to produce reports.Optional Enercept Display Interface acts as a stand-alone operator interface supporting up to 32 meters (63 with a repeater). In addition, the EDI can act as a network adapter allowing Enercept meters to be incorporated into a 4-wire network. The Enercept Network Adapter (ENA) is designed to act as a network adapter, allowing the Enercept meters to be integrated into a PowerLogic 4-wire network. The ENA converts the signals from the 4-wire network to the 2-wire network, as well as changing the parity between the two networks.
