Bender VMD423-D-2 LINETRAXX Spannungs- & Frequenzüberwachungsrelais 3-phasig

The Bender LINETRAXX VMD423-D-2 is a multifunctional monitoring relay designed for precise voltage and frequency supervision in 3-phase AC systems. It's particularly suited for applications involving private power generation systems, such as photovoltaic installations, wind turbines, and combined heat and power plants, ensuring compliance with grid connection standards. Comprehensive Monitoring: Detects undervoltage, overvoltage, underfrequency, overfrequency, phase asymmetry, phase failure, and incorrect phase sequence in 3(N)AC systems up to 500 V. Average Overvoltage Detection: Monitors overvoltage conditions by calculating the average over a 10-minute interval, enhancing accuracy in fluctuating conditions. Adjustable Parameters: Features configurable start-up delay, response delay, and.
