AC/DC Withstanding Voltage & Insulation Resistance Tester

The AT9620 AC/DC Withstanding Voltage & Insulation Resistance Tester integrates multiple safety testing functions including electrical strength (AC/DC withstanding voltage) and insulation resistance measurement. It is essential testing equipment for electrical product manufacturers and quality inspection departments.

The AT9620 uses a high-speed microprocessor as its control core, capable of measuring all safety parameters of the device under test in real time, completing three tests within 4 seconds, making it ideal for production line rapid testing requirements.

The AT9620 features a 5-inch color LCD touchscreen for easy operation, with intelligent upper/lower limit judgment for automatic defect identification. The circuit employs multiple anti-interference measures for strong noise immunity. Both hardware and software protection ensure high instrument reliability. Automatic over-voltage and over-current protection provide enhanced safety.

This series of testers adopts Sinusoidal Pulse Width Modulation (SPWM) technology for contactless high-voltage regulation, combined with hardware and software protection to significantly improve instrument reliability.
