CARLO GAVAZZI Phase Loss & Phase Sequence Monitoring Relay - DPA03CM23
The CARLO GAVAZZI DPA03CM23 is a high-precision 3-phase monitoring relay designed for detecting phase loss and incorrect phase sequence in industrial power supplies. Manufactured in Italy, this relay ensures reliable operation of three-phase systems by monitoring voltage levels and phase sequence, providing essential protection for industrial equipment.
Key Features
Monitors 3-phase power supply for correct phase sequence and phase loss
Knob-adjustable undervoltage detection for flexible sensitivity settings
Self-powered operation measuring its own supply voltage
Output: 8 A SPDT relay, normally energized
Mounting options include DIN-rail (DPA03) or plug-in module (PPA03)
Housing sizes: 22.5 mm Euronorm (DPA03) or 36 mm plug-in (PPA03)
Detects correct phase sequence and presence of all phases
Releases when a phase is missing or phase sequence is incorrect
Adjustable undervoltage setpoint via front knob
Self-monitoring of supply voltage
Application
Ideal for industrial automation, motor protection, and power system monitoring where phase integrity is critical.
Note: Specifications are subject to change without notice. For more detailed information, please refer to the datasheet. If additional details are needed, search the internet for the part number.
Unfortunately I havent tested the 5G, Only difficult part was connecting antennas. But everything is good, by default it runs on Qualcom's QMI mode, Had to switch to MBIM and it works good with Windows. Planning to run with OpenWRT soon.
