Comprehensive Transformer Testing Systems
Transformer Tester

5236 transformer tester, test frequency is 20Hz~500kHz, 20 test points. By adopting innovative patent design, this tester is able to meet all your test requirements for multi-pin network communication transformer under the same volume condition. To prevent the fixture interference from affecting measured values during testing, the software has high-frequency compensation function (zero-setting when the fixture encounters Open/Short), which makes the readings from fixture are almost the same as measured values therefore increase the tester credibility. The best choice for transformer testing. The application of the transformer tester includes power transformers and network communication transformers, etc.

  • Basic Accuracy up to 0.1%
  • Support computer software connection and advanced software editing function
  • Innovative fixture zero-setting function to successfully prevent fixture interference from affecting the accuracy of measured values due to high test voltage
  • Able to test 30 items per second under fastest test speed. Elevate productivity significantly through auto-scan function
  • Paired with a 20-pin fixture to meet the test requirements for multi-pin network communication transformer
  • Optional 100mA DC Bias / 5x38 model is equipped with Meter Mode function / Support USB interface for data storag
