ON-OFF Cycling

Electrical Stress includes equipment ON-OFF cycling. 

Since the capacitor can be regarded as a short circuit in a transient state, when the switching power supply is powered on, a very large inrush current will be generated, and the amplitude of the inrush current is much larger than that of the steady-state operating current. If the inrush current is not limited, not only It will burn out the fuse, burn out the connector, and also interfere with nearby electrical equipment due to the common input impedance. Therefore, a switch impact test is required to verify the safety of the switch.

Scope of service: electrical products

Standard: UL, GB, etc.
