C: Effective pulse recommended
Use the ICP-S so that the open-circuit voltage between the terminals after the ICP-S breaks
the current will be a maximum of 50 V. Unless the ICP-S is used under these conditions, the
mold may be damaged or internal resistance may remain after the ICP-S breaks the current.
may be damaged by arcing after the ICP-S breaks the current.
