EM271 Multi-Channel Power Analyser
Multi-load power analyser for single or three-phase systems installable on panels or DIN rails. Manages current input via two groups of split-core current sensors connected with RJ-11 connectors.
The EM271 is equipped with a LCD display with 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.
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 only once.
• 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 up to 6 single-phase loads).
• Specific software. The UCS proprietary configuration software enables rapid configuration and the display of all measurements. The software and subsequent updates are free.
• Tamper-proof. Configuration access can be locked. The terminals and display can be sealed.
• Self detection of primary current of the TCDxM (the dedicated current transformers).
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 analyzers 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.
