EM271 Multi-channel power analyzer Benefits Reduced installation time and errors. Equipped with detachable terminals for all connections, with possibility of requesting pre-wired cables (optional). Connected to two groups of split-core current sensors with two cables fitted with RJ-11 connectors. For connections in cascade of multiple EM271s the voltage reference is required once only. Installation flexibility. It can be installed in new or existing single- and three-phase systems. Suitable for panel or DIN rail mounting . Granular analysis. It provides total measurements or single load measurements (up to 2 three-phase loads or Description up to 6 single-phase loads). Specific software. The UCS proprietary configuration software enables rapid configuration and the display Multi-load power analyzer for single or three-phase of all measurements. The software and subsequent systems installable on panels or DIN rails. updates are free. Manages current input via two groups of split-core Tamper-proof. Configuration access can be locked. The current sensors connected with RJ-11 connectors. terminals and display can be sealed. The EM271 is equipped with a LCD display with Self detection of primary current of the TCDxM (the dedicated current transformers). controls to display measurements and configure the system, a RS485 port and two pulse outputs or two RS485 ports for daisy chain connections. Thanks to the SUM function, it also displays total load consumption values. Applications EM271 is connected directly to current sensors in switchboards for simultaneous monitoring of multiple single- or three-phase loads in low voltage systems. Created for both commercial and industrial environments (e.g. data centers), this device guarantees quick and space-saving installations with just a few simple connections. Suitable for retro-fit applications and for new installations where more flexibility is required. Main functions Measurement of energy consumption and main electrical variables of single- or three-phase loads. Display of single load measurements and total measurements Transmission of data via serial communication. Transmission of power consumption via pulse output (optional). 20/10/2017 EM271 DS ENG Carlo Gavazzi Controls S.p.A. 1EM271 Architecture RJ11 TCD M EM 271 VMU-C EM TCD M RS485 RJ11 TCD M EM 271 TCD M n n n n Main features Up to 2 three-phase loads or 6 single-phase loads managed simultaneously. Up to 400 A input current via pre-cabled groups of current sensors (TCDxM) or any primary current of current up to 10000 A sensor with 0.333 V secondary output (via connection adapter TCDMM). Three installation configurations: on DIN rails, mounted on panel of 72 x 72 or 96 x 96 (with optional adapter) Single load measurements: V, A, W/VA/var, kWh, kvarh. Total load measurements: W/VA/var, kWh, kvarh. Display of electrical variables: 3 digits. Display of energy meters: 7 digits. Accuracy: better than a combination of a class 1 meter and a class 0.5 current transformer. Easy connection function. Up to 20 EM271 connected in cascade. RS485 port. Optional outputs: additional RS485 port for chain connection or two pulse outputs. Self power supply via voltage inputs. Detachable terminals and sealable terminal caps. Configuration via keypad or UCS configuration software. 20/10/2017 EM271 DS ENG Carlo Gavazzi Controls S.p.A. 2
