Profile:
KDB-II is an innovative transformer turns ratio tester that overcomes the limitations of traditional bridge circuits. It features a high-resolution LCD screen and lithium battery power, making it suitable for field use. It offers a wide measurement range (0.9-10000) and high accuracy. It supports testing of transformers, Z-type transformers, voltage transformers (PTs), and current transformers (CTs), and adds a current transformer (CT) polarity testing function. With its blind testing capability, comprehensive protection, and portable design, it provides professional diagnostic capabilities in various environments.
Features:
1. Adaptive Power Supply: Built-in lithium battery (over 8 hours of runtime) or AC220V power supply, supporting over 100 transformer tests per charge;
2. Blind Testing Function: Test turns ratio and grouping without needing to understand high/low voltage connections;
3. Extended Applications: Tests conventional transformers, Z-type transformers, voltage transformers (PTs), and adds current transformer (CT) turns ratio and polarity testing functions;
4. Wide Measuring Range and High Accuracy: Measuring range 0.9-10000, with a maximum accuracy of 0.3%;
5. Comprehensive Protection: Features reverse connection protection and output short circuit protection;
6. 5.6-inch industrial-grade high-brightness color LCD display, clearly visible even in strong light;
7. Built-in thermal printer for convenient data printing;
8. Dual Storage: Built-in memory and USB drive for data storage.
