AV-40DC High Voltage Detector
AV-40DC High Voltage Detector

Description:
The AV-40DC High Voltage Detector is a professional-grade voltage indicator engineered for safe detection of electrical presence across a wide range of applications. This versatile tool operates effectively from 120V to 40kV, making it suitable for secondary and overhead voltage work in utility, industrial, and maintenance environments. Equipped with dual alert systems—both audible and visual alarms—the detector provides immediate confirmation of voltage presence, ensuring operators receive clear notification regardless of ambient noise levels. The intelligent activation threshold responds to proximity to energized or grounded objects, requiring a minimum of 50% of the selected voltage rating for reliable detection. This proximity-based sensitivity helps reduce false positives while maintaining consistent performance across different electrical configurations. The selector switch allows technicians to calibrate detection thresholds for specific voltage ranges, adapting the tool to various job requirements. Designed for direct contact voltage detection, the AV-40DC delivers the dependable performance and safety features that electrical professionals demand when working with high-voltage systems.
