Product Description And Application

WBV344U05-S adopts the principle of modulation and demodulation isolation to measure the DC voltage in the power grid or circuit in real time and transform it into a standard DC current (Iz) output. It has the characteristics of high accuracy, high isolation, low drift, and wide temperature range. The power supply, input and output circuits are completely isolated and can be directly connected with various A/D converters to form a centralized data acquisition system. This product is suitable for real-time detection of power systems, post and telecommunications systems, railway monitoring systems, etc.
