The Electrex Femto and Atto are respectively an extremely versatile, precise and microprocessor based energy meter/analyser and energy transducer/analyser. Designed to satisfy the most sophisticated applications for monitoring electrical parameters and managing energy in the civil, commercial and industrial sectors. Equipped with RS485 port, LED for active energy, indication of the phases sequence, 4 x operating time counters and firmware that can be upgraded remotely. Available in versions with digital inputs and / or digital or analogue outputs. Compliant with EN 50470-1 + EN 50470-3.
Measurements in True-RMS are obtained by continuously sampling the waveforms of voltages and currents, and the automatic off set compensation of the internal amplifiers ensure maximum precision regardless of the variability of loads over time (ex. spot welders), from the signal level and the environmental operating conditions. The 64-bit resolution also ensures a high accuracy of the energy measurement even in the presence of small loads (e.g. equipment in stand-by).
