WBV412D01 (High Accuracy AC Voltage Sensor) uses a special isolation module to measure the power-frequency AC voltage in the power grid and circuits in real time and convert it into a standard DC voltage (Uz) output. It features high precision, high isolation, wide frequency response, low drift, low power consumption, a wide operating temperature range, and a compact size. The High Accuracy AC Voltage Sensor is suitable for power equipment, power network monitoring and automation systems, industrial control monitoring systems, railway signal systems, etc.
