IEC 60335-1 12.5kV 1.2/50 μs Transient Voltages Test Generator
Product information:
This impulse voltage test generator is required by IEC60335-1 clause 14, IEC60065:2014 clause 10.2, 13.3.4 a), and IEC 60065:2014 clause 13.3.4 b), 14.2, IEC60950, and etc.
It is used to detect the transient over voltage of the components and the electrical clearance and the creepage distance of household appliance, Audio, video and similar electronic apparatus.
This impulse voltage test generator is a standard lightning wave test device with waveform 1.2/50µs. Wavefront time is 1.2µs, wave after time is 50µs, it is a destructive tester. The sample breakdown will produce a spark and acoustic, instrument peak voltage than the no-load voltage is decreased substantially (close to zero), when applying the same voltage in the next test, it will also show the above phenomenon.
