SYZ-100A DC resistance tester Features: 1. The whole machine is controlled by high-speed single-chip microcomputer, with high automation and easy operation. 2. Using high-frequency switching power supply technology, the output current is large, suitable for DC resistance measurement of large and medium-sized transformers. 3. The protection function is perfect, it can reliably protect the impact of the back EMF on the instrument, and the performance is more reliable. 4. With sound discharge alarm, the discharge indication is clear, reducing misoperation. 5. The response speed is fast, the on-load tap-changer can be directly converted in the measurement state, and the instrument automatically refreshes the data. 6. The vertical chassis structure is adopted for on-site use. 7. Intelligent power management technology, the instrument always works in the minimum power state, effectively reducing the internal heat of the instrument and saving energy. Can work for hours without interruption. 8. Dot matrix LCD, Chinese menu, printout. Technical Parameters: Output current: 10A, 20A, 40A, 100A Range: 10μΩ～100mΩ (100A) 100μΩ～500mΩ (40A) 200μΩ～1Ω (20A) 500μΩ～2Ω (10A) Accuracy: 0.2% Resolution: 0.1μΩ Working temperature: 0 ~ 40 ° C Ambient humidity: ≤90% RH, no condensation Working power supply: AC220V±10%, 50HZ±1HZ Net weight: 17KG Dimensions: 400mm*230mm*380mm
