CARLO GAVAZZI DPC71DM48 3-Phase Voltage Monitoring Relay
The CARLO GAVAZZI DPC71DM48 is a versatile multifunction relay ideal for monitoring 3-phase power systems. It provides comprehensive protection by detecting various faults including over/under voltage, incorrect phase sequence, phase loss, asymmetry, and voltage tolerance. The relay is designed for DIN rail mounting and features LED indication for power supply, alarm, and relay status. It's suitable for applications such as motor protection, generator monitoring, and industrial automation where reliable power monitoring is critical. The relay's ability to monitor both phase-phase and phase-neutral voltages, along with adjustable setpoints and delay functions, makes it a flexible solution for a wide range of industrial environments.
