The SCR Make Surge Current Testers are designed for interference test as per IEC 60065. Surge Tester is intended for testing of insulating materials, and for testing of particular components in mains operated electronic apparatus for household and telecommunication. This is tested with high voltage surges 10kV.
The Surge Testers will produce a current surge with the required wave-shape of 8 / 20 microsecond, meaning a high current surge with 8 microseconds rise time and 20 microseconds fall time.
