Energy analyzer for three-phase and two-phase systems

Description:

EM530 is an energy analyser connected through 5 A or 333 mV current transformers, or Rogowski coils without external integrator, for two- and three-phase systems up to 415VL-L. In addition to a digital input, the unit can be equipped, according to the model, witha static output (pulse or alarm), a Modbus RTU communication port, or an M-Bus communication port.

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. EM530 complies with the precision international standard EN IEC 62053-21, and with the performance requirements (power and active energy) set out by EN IEC61557-12. EM540 complies with the precision international standard EN IEC 62053-21, and with the performance requirements (power and active energy) set out by EN IEC61557-12..
• 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, with operating temperature up to 70 °C / 158 °F .
• Powerful integration. 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.

Applications:

EM530 can be installed in any low-voltage switchboard to monitor energy consumption, main electrical variables, and harmonic distortion. It is compatible with current transformers with 5 A / 333 mV secondary current, as well as Rogowski coils, which the device supports without the need for external integrators or power supply. The device supports systems with rated current up to 10 kA and is suitable for retrofit applications whenusedwithopenable transformers like CTA, CTD S, CTV, or ROG4X. If used to monitor a single machine, it provides all the main electrical variables to identify any possible malfunction in its early stage and can correlate the energy consumption with the hours of operation, to plan maintenance and prevent failures. The partial meter reset function, easily implementable by means of a digital input, allows you to monitor each individual machine cycle.
