Energy Management Energy Analyzer Type EM271 • Equivalent to Class 1 (kWh) of EN62053-21(EM271 Base only) • Equivalent to Class 2 (kvarh) of EN62053-23 (EM271 Base only) • Equivalent to Class 1 (TCDM split-core current sensors accessory only) • Virtual meter (sum of two 3-phase or six 1-phase loads) • Energy meter with 6+1 DGT readout • Current measurement up to 400 A with external TCDM current transformer accessories • Single phase variables: V, A, kW • Total energy measurements: total kWh and kvarh • Self power supply • RS485 serial communication port (standard) • 2 programmable pulsating outputs (optional) • Fast installation system by: - Detachable dual voltage terminal blocks - Daisy-chain of max 20 EM271 by dual voltage terminal blocks - Detachable serial and pulse outputs terminal blocks - RJ11 connection for external TCDM current trans- formers • Overall dimensions: 72x72 mm • Protection degree (front): IP50 Product description Dual three-phase energy me- ter with built-in configuration key-padand LCD data dis- playing capable to measure the consumed energy (and other electrical parameters) by up two three-phase loads or by up to six single-phase loads.Housing forboth DIN-railandpanelmount- ing with IP50 (front) protec- tion degree. The voltage connectionsare carried out by a couple of detachable terminals so to allow a very fastdaisychaininstallation of multiple meters. Measure- ment of the current up to 400 A with external split core cur- rent transformer accessories connected by RJ11. Moreo- ver the meter is provided either with two pulsating outputs proportional to the active energy being meas- ured(e.g.oneforlighting load and one for power load) and a serial RS485 portor with a dual serial RS485 port based on detachable termi- nals for a fast installation. A virtual energy meter can be enabled to provide the total consumptions dataofthe two 3-phase loads (or of the six 1-phase ones). Specification are subject to change without notice EM271 DS 1702151
