The KDZD5550 Automatic Insulation Breakdown Voltage Tester is a professional high-voltage testing system compliant with GB1408.1-2006. It integrates a microcontroller module, data acquisition module, and computer control system for fully automated testing without manual intervention. Equipped with a 7-inch touchscreen, it enables intuitive operation and real-time test monitoring. The system supports curve analysis via computer connection and features parameter memory function for repeated testing efficiency. With multiple safety protection mechanisms and 10-group test data storage, it ensures accurate, safe, and efficient insulation performance assessment for various materials.

• Touchscreen operation for simple and intuitive parameter setting and control.
• Test parameter memory function retains settings after power-off for quick reuse.
• Simplified test interface and clear function labeling for easy operation.
• Stores up to 10 groups of test data for convenient comparative analysis.
• Real-time display mode for direct visualization of the entire test process.
• Multiple safety protections: door limit, voltage zero, and over-voltage protection.
• Voltage zero protection resets to initial zero voltage after power interruption.
• Over-voltage protection automatically terminates testing when exceeding the set limit.
• High-voltage limit protection prevents over-rise when the control system malfunctions.
• Running indicator light for clear status identification during operation.
