Single-phase energy devices
Carlo Gavazzi has introduced its new compact EM10 and EM11 Series Energy Meters. The EM10 Series is a single-phase energy meter that monitors 120 or 230 VAC. It provides a cost-effective solution for most metering applications, allowing an effective energy measurement without the need for an external current transformer, the company says. This ultra-compact device can be interfaced with a PLC, thanks to its optional pulse output. The EM11 Series is also a 120 or 230 VAC single-phase device that provides information concerning the status of the power supply, in conjunction with energy measurement. It is the ideal solution for any application requiring a power analyser to display and control the main energy supply. It prevents line overload conditions by switching off selected non-priority loads through its alarm output. It controls and limits power before a shutdown of the entire electrical system occurs. It is also suitable for metering most commercial and industrial applications.
