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.
