Bypass Diode Comprehensive Tester

Product description Specifications Download

      Meets the bypass diode thermal test requirements in the 4.18 clause of the IEC 61215-2016 and MST25 clause of the IEC 61730 standard. Meets the bypass diode thermal runaway test requirements specified in the IEC 62979 standard. 


Intelligent control of the current value, emit pulse current within 1ms.

During pulse current, parameters such as pulse current, diode voltage drop, and junction box temperature are collected

Automatically simulate the relationship between VD and TJ by least squares method;

 Calculate the Vd of 75°C when the ID=Isc the TJ value at 75°C;

 All data can be exported in EXCEL format for  processing and analysis.

Test the functionality of the diode.

The time for forward power to reverse power supply is ≤10ms;

High-speed acquisition card collects voltage, current and temperature data during the conversion phase;
