MICROTEST 2-in-1 Transformer Testing System (Low Voltage+Safety)

20 Channels Transformer Tester

The MICROTEST 2-in-1 Transformer Integrated Test System is a comprehensive solution that combines low-voltage electrical characteristics testing and safety compliance testing. It offers 20 testing channels and integrates low-voltage testing (including inductance, leakage inductance, resistance, capacitance, etc.) with AC/DC withstand voltage insulation testing (up to 5000V/6000V). It ensures efficient and convenient testing for transformer products.

To measure the inductance value of a transformer, you can use an LCR meter, which offers selectable test frequencies including 200kHz, 500kHz, and 1MHz. It supports software that allows connection to a PC, enabling the storage of test data.
