MAR144 Network Analyzer

Panel-mounted three-phase network analyser designed for the measurement, display and monitoring of electrical parameters in low-voltage installations. It is a microprocessor-controlled unit, with three independent LED displays and an integrated keypad, allowing simultaneous clear and direct visualisation of different electrical magnitudes from the front of the panel.

The MAR144 offers 4-quadrant measurement, True RMS, and MAX/MIN value logging, making it a robust solution for industrial applications, distribution boards, and control centres where reliable local visualization, signalling capability and the option of integration into supervisory systems via serial communications are required. It is available in single-phase and three-phase versions (3 and 4 wires), adapting to different network configurations.

Description: The analyser MAR144 is an instrument with a programmable microprocessor, three LED displays for measurement indication and an integrated keyboard.
