The YCV8-02 modular relay from CNC Electric is designed to monitor and protect electrical systems operating at AC220V. It uses True RMS measurement to ensure precise voltage detection, even under waveform distortion. The relay allows users to select the operating mode and voltage threshold via a rotary knob, offering flexible configuration.
It provides protection against over-voltage, under-voltage, and phase failure, and supports normal/emergency power switching. The LED indicators display supply and output status clearly. Its 1-module DIN rail mounting ensures easy integration into control panels and distribution boards.
This relay is suitable for use in residential buildings, non-residential facilities, energy infrastructure, and mobile equipment such as site machinery and refrigerated trucks.
