WBV342U01-S (10mV–1000V Input DC Voltage Sensor) converts pure DC input voltage into a load-independent DC output signal of 0–5V or 0–10V. The 10mV–1000V Input DC Voltage Sensor adopts a modulation-demodulation isolation principle and an average measurement method for real-time measurement of DC voltage from the power grid or electrical circuits.
The 10mV–1000V Input DC Voltage Sensor offers advantages such as full galvanic isolation between input and output, high accuracy, low temperature drift, and a wide operating temperature range.
Advantages
* High isolation withstand voltage
* Good EMC compatibility
* High reliability
* Low drift
* Four product series with over 2,000 models available
* Customization supported
Applications
* Intelligent low-voltage power distribution systems
* DC power panels and box-type substations
* Temperature and fire monitoring for transformers, and fire monitoring for cables
* Fiber optic temperature measurement systems for high-voltage switchgear
* Transformer contact monitoring
