500v Input Dc Voltage Sensor Ce Certification WBV334H29

500v Input Dc Voltage Sensor Ce Certification WBV334H29

WBV334H29 adopts the principle of modulation and demodulation isolation to measure the pulsating DC voltage in the power grid or circuit in real time, and convert it into a standard DC current output, with high accuracy, high isolation, low drift, wide temperature range, etc. This product uses AC or DC 220V power supply. The three circuits of power supply, input and output are completely isolated. It can be directly connected with various types of 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.
