Characteristics
This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the actual
load.
Wave is standard shock voltage of 1.250s according to JEC-212-1981.
Refer to “6. Usage, Storage and Transport Conditions“ in
The max. operating speed amounts to 30cps without load.
