Three-phase electric energy meter
ELECTREX

Analyzer, counter and multimeter extremely versatile and precise designed to meet the more sophisticated applications of monitoring of the electrical parameters and management of consumption of electricity in the civil, commercial and industrial sector.

A specific version of the Femto has been designed for the measure in direct current, for example in applications in the context of photovoltaic systems.

Versatility - Only one instrument for every kind of insertion. In fact the Femto is suitable for application over all types of electric grid, single, bi phase or tri-phase with 3 or 4 wire, symmetric or asymmetric, balanced or unbalanced, low or medium tension; with 1, 2 or 3 CT.

Digital input and outputs / alarms - Femto is equipped by series of 1 input and 2 digital outputs optically insulated. The input is used to count signals of external pulses (e.g. gas counters, water, pieces, etc.), or to detect the state (e.g. ON/OFF in machines, switches, etc.). While the 2 outputs may transmit pulses proportional to the active and reactive energy (e.g. for PLC), internal alarms or can be used as units of output controlled remotely.

Readings: precision and reliability - Over 60 True-RMS value readings on 2 and 4 quadrant (import/ export), up to the 31st harmonics. Maximum precision also in the presence of quickly variable loads (e.g. spot welders).
