The WBV334U01-S is a high-precision DC voltage sensor based on modulation-demodulation isolation principle. It is specifically designed for real-time monitoring of pulsating DC voltages in power grids and circuits. It accurately converts the measured voltage into a standard DC current signal output. With high isolation, high stability, and strong adaptability as its core advantages, it is widely used in key fields such as power, communications, and rail transportation, serving as a core sensing unit for industrial data acquisition and system monitoring.
This sensor employs modulation-demodulation isolation technology. Through a complete link of signal modulation, isolated transmission, and demodulation restoration, it achieves complete electrical isolation between the input and output circuits. The isolation voltage can reach DC 2500V (1 minute), effectively blocking the electrical coupling between the high-voltage and low-voltage sides, preventing interference signals from entering, and ensuring measurement safety and system stability. Its input range covers a wide range of 10mV to 1000V, adaptable to various levels of pulsating DC voltage measurement needs; the output is a standard 4~20mA DC current signal, with load-independent characteristics, and can be directly connected to various A/D converters, PLCs, DCSs, and data acquisition modules without additional signal conditioning, quickly building a centralized data acquisition system.
In terms of core performance, the WBV334U01-S boasts 0.2-level high accuracy with extremely small measurement errors, accurately capturing minute voltage fluctuations; it adopts a low-drift design with a temperature drift of only 200×10⁻⁶/℃, maintaining stable accuracy even after long-term operation in a wide temperature range of -25℃ to +70℃, unaffected by temperature changes. With a response time ≤350ms, it can quickly respond to dynamic voltage changes, meeting the needs of real-time monitoring and fault early warning; it also has twice the rated input overload capacity, ensuring no damage to the device during short-term overload, making it suitable for complex industrial environments. The product features DIN rail mounting, a compact structure, and convenient installation, making it suitable for integrated deployment within control cabinets while balancing space utilization and ease of maintenance.
The WBV334U01-S has applications covering multiple key areas, providing reliable support for power monitoring and system control across various industries. In power systems, it is widely used for voltage monitoring of DC buses, energy storage battery banks, and rectifier equipment in substations, distribution networks, and new energy power plants. It collects voltage data in real time, providing a basis for grid dispatching, fault diagnosis, and power quality analysis, ensuring the safe and stable operation of the power system. In the telecommunications field, it is compatible with DC power supply systems, UPS power supplies, and battery bank voltage monitoring in communication base stations and data centers, ensuring stable power supply to communication equipment and preventing communication interruptions due to abnormal voltage.
