8.2.14 Residual Voltage Immunity in Standby Mode
The PS supply should be immune to any residual voltage placed on its outputs (Typically a
leakage voltage through the system from standby output) up to 500mV. There shall be no
additional heat generated, nor stress of any internal components with this voltage applied to any
individual output, and all outputs simultaneously. It also should not trip the protection circuits
during turn on.
The residual voltage at the power supply outputs for no load condition shall not exceed 100mV
when AC voltage is applied.
