Product Description

 

 

IEC62368-1 300V Limited Short Circuit Current Withstand Test System

 

Complied Standards & Clauses


 

Conforms to Appendix R in IEC62368-1:2019.

 

Product Overview


 

The system uses an energy storage device to store energy according to the set parameters, and discharges when the set voltage is reached to realize the large current output test function. The attenuation oscillation frequency of the current is 50±2Hz, simulating the power frequency, and the peak current can reach 14KA (10KA sine wave peak), it will automatically charge for the next round of testing after the discharge is completed.

During the test process, the discharge current waveform is recorded and the current-time curve is automatically generated.

Meet the testing requirements of power supply power of 300V*10KA=3MVA in ordinary laboratories;
