DESCRIPTION

The EM11DINAV81XR1X is a single-phase energy analyzer designed for active and reactive energy measurement in electrical systems. It features a 230V AC rated input with a current range of 5(32)A, self-power supply operation from 48 to 62Hz, and an LCD display with alphanumeric indication for configuration and variable display. The device achieves Class 1 accuracy (±0.5% RDG) for active energy (kWh) according to EN62053-21 and Class B accuracy according to EN50470-3, with Class 2 accuracy for reactive energy (kvarh) per EN62053-23. It provides instantaneous measurements of voltage, current, active power, reactive power, power factor, and frequency, along with total energy accumulation in kWh and kvarh. The analyzer includes TRMS measurements for distorted sine waves, a built-in configuration push button, optional pulse output (open collector) or alarm relay output, and operates over a temperature range of -25°C to +55°C, making it suitable for energy monitoring, demand management, and fiscal metering applications when certified under the MID Directive.
