DRM-20S DC Winding Resistance Tester
• An innovative solution that allows for full testing with a single wiring connection, improving on-site testing efficiency.
• Flexible switching between multiple modes, including single- and three-phase Yn-type simultaneous testing and three-phase Y-type and △-type phase-by-phase testing, meets diverse testing needs.
• Three-phase automatic testing and precise calculation of three-phase imbalance ratios provide quantitative winding performance data, enabling accurate analysis of test results.
• Yn winding neutral point lead wire resistance testing minimizes deviations from single-phase test standards and enhances data reliability.
• Built-in demagnetization and assist functions provide core technical support for test data accuracy.
• Equipped with a 7-inch full-touch smart screen with a 400cd/m² high-brightness display, the device offers smoother touch operation and a clearer viewing experience.
• Supports fixed and automatic outputs, accurately adapting to the test product's resistance value and empowering the device with adaptive adjustment capabilities.•
• Multiple protection mechanisms, including power failure, back EMF, and disconnection, provide a robust safety barrier for the device and testers. 9. Integrated smart printing function makes test result output more efficient and convenient.
