EM540 Energy analyser for three- and two-phase systems
■EM540 is a direct connection energy analyser, for two- and three-phase systems up to 415 V L-L and current up to 65 A.
■In addition to a digital input, the unit can be equipped, according to the model, with a static output (pulse or alarm), a Modbus RTU communication port or an M-Bus communication port.
●Benefits
■Enhanced readability. The backlit display ensures perfect visibility even in low light. The different size of the digits preceding and following the dot makes the displayed values easier to read, while the essential style of the units of measure allows you to readily understand the available variables.
■Easy browsing. Page configuration and browsing are very intuitive, thanks to the user interface with 3 mechanical keys. The slideshow function automatically displays the desired measurements in sequence, without having to use the keyboard; the page filter allows you to hide the unnecessary information.
■Quick configuration. The configuration wizard which runs when the system is started up for the first time allows you to commission the unit without errors in a matter of seconds. The UCS configuration software is available for download free of charge.
■Accurate measuring. EM540 complies with the precision international standard IEC/EN62053-21, and with the performance requirements (power and active energy) set out by IEC/EN61557-12
■Fiscal metrology. The sliding terminal caps (patent application pending in EU, US, CA, AU), can be sealed to prevent any tampering with the connections, allowing the unit, thanks to the MID certification, to perform measurements for fiscal purposes and a reinforced protection toward the power terminals.
■Flexible installation. It can be installed in two-phase, three-phase with neutral, three-phase without neutral, and wild-leg three-phase low-voltage systems.
■In combination with UWP (an energy monitoring and control gateway manufactured by Carlo Gavazzi), it allows you to build a scalable and flexible system to monitor the energy efficiency of buildings and equipment.
●Main features

■Displaying of the consumed active energy with a resolution of 0.001 kWh
■The frequency value is available via Modbus, with a resolution of 0.001 Hz
■Average value calculation (dmd) for current and power (kW / kVA)
■Streamlined user interface featuring 3 mechanical buttons
■Modbus RTU RS485 (data refresh every 100 ms)
■Continuous sampling of each voltage and current
■Backlit LCD display
■MID certified version
■MID-certified meter resolution 0.001 kWh
■cULus approved (UL 61010)
■Compliance with the performance requirements set out by IEC/EN61557-12 (power and active energy)
