KH enhanced type (complete machine standard)
1.Comply with the overall machine standard: IEC61000-4-5, GBT17626.5 "Electromagnetic Compatibility Testing and Measurement Technology Surge (Impact) Immunity Test", using 4 phase angles of AC voltage, each phase angle is positive or negative 5 impacts each, totaling 40 impacts;
2. Impact peak
5D:1KV/0.5KA 7D:2KV/1KA
10D:4KV/2KA 14D:6KV/3KA
20D:10KV/5KA
3. Voltage specification: V1mA≥430V, that is, 431 and above specifications;
4. Combined wave: open circuit is voltage wave 1.2/50μs, short circuit is current wave 8/20μs, superimposed AC voltage
KX customized
1. Lightning strike requirements are higher than KH level, such as
A. The peak value of one impact (Imax) is required to be higher than KH. For example: 14D product requires Imax≥10KA
B. The number of surge impacts (In) requires a large number of impacts. For example: 14D product requires 6KV/3KA combined wave impacts 100 times, 500 times...
2. Miniaturization requirements: 10D replaces 14D, 14D replaces 20D, 20D replaces 32D... Suitable for SPD product applications
