EM270WSTS Carlo Gavazzi

EM270 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 current transformer blocks with two cables fitted with RJ-11 connectors. For connections in cascade of multiple EM270s the voltage reference is required only once. Installation flexibility. Suitable for panel or DIN rail mounting. Granular analysis. It provides total measurements or single circuit measurements (up to 2 three-phase circuits or up to 6 single-phase circuits). Description Specific software. The UCS proprietary configuration software enables rapid configuration and the display of all measurements. The software and subsequent Multi-circuit power analyzer for single or three- updates are free. phase systems installable on panels or DIN rails. Tamper-proof. Configuration access can be locked. The Manages current input via two current transformer terminals and display can be sealed. blocks connected with RJ-11 connectors. Self detection of primary current of the TCD (the The EM270 is equipped with a LCD display with 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. Applications EM270 is connected directly to current sensors in switchboards for simultaneous monitoring of multiple single- or three-phase circuits 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. Main functions Measurement of energy consumption and main electrical variables of single- or three-phase circuits. Display of single circuit measurements and total measurements. Transmission of data via serial communication. Transmission of power consumption via pulse output (optional). Main features Up to 2 three-phase circuits or 6 single-phase circuits managed simultaneously. Up to 630 A input current via solid-core current transformer blocks (TCDxX or TCD0W). Three installation configurations: on DIN rails, mounted on panel of 72 x 72 or 96 x 96 (with optional adapter). Single circuit measurements: V, A, W/VA/var, PF, kWh, kvarh. Virtual circuit (sum or difference) measurements: W/VA/ var, PF, 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 EM270 connected in cascade.
