Real time monitoring and digital display of U1, U2, U3 three-phase voltage values in three-phase AC circuits, while supporting functions such as parameter setting, data remote transmission, and alarm linkage. Widely used in distribution cabinets, electrical control cabinets, and industrial automation systems to achieve real-time monitoring of grid voltage, abnormal warning, and equipment protection, ensuring stable operation of the power supply system.


Advantages:
·Three phase display on the same screen, presenting three-phase voltage simultaneously, intuitively grasping the balance status of the three phases.
·High measurement accuracy, high-precision sampling chip, measurement error ≤ 0.5%, meeting industrial grade measurement requirements.
·Strong communication and expansion, standard RS485/Modbus, optional 4-20mA output, relay alarm, seamless integration with DCS/PLC.
·Universal and convenient installation, standard 96 × 96mm panel embedded installation, suitable for mainstream distribution cabinet openings.
·The operation is simple and intuitive, with 4 keys (SET/up/down/back), and on-site one click configuration of variable ratios and parameters.
·Excellent anti-interference ability, built-in EMC electromagnetic filter, stable data without jumping in industrial environments.
·Wide range adaptability is good, supporting direct measurement of 0-450V or range expansion through transformers, and versatile for multiple scenarios.
