Why Choose the Carlo Gavazzi DUB03CW24 Voltage Monitoring Relay?
The Carlo Gavazzi DUB03CW24 is a precise and reliable single-phase AC/DC voltage monitoring relay designed to protect electrical systems by detecting overvoltage and undervoltage conditions. As part of the advanced Carlo Gavazzi DUB03 monitoring relay series, it provides dependable voltage supervision for industrial automation, electrical control panels and machinery protection applications.
This monitoring relay continuously monitors its own supply voltage and switches its relay output when the measured voltage moves outside the configured limits. With true RMS measurement, selectable measuring ranges, adjustable voltage thresholds, hysteresis control and a built-in latch function, it provides flexible protection for demanding industrial environments.
With a 12–240 V AC/DC monitoring range, a self-powered design and a SPDT relay output, the DUB03CW24 is ideal for applications requiring reliable overvoltage and undervoltage monitoring in industrial control systems.
