1) Power supply requiring AC withstanding

Application:SW power supply, inverter power supply, power supply of office and home appliance


IEC62368-1 requires series usage of MOV ※ 1) and GDT ※ 2) for surge protection in the primary circuits of equipment.


※1) The MOV complies with the requirements of AnnexG.8.
※2) The GDT complies with :
*the electric strength test for BASIC INSULATION ; and
*the external Clearance and Creepage distance requirements for basic insulation.
