Standby Power Cosumption with System:For computers and displays, ENERGY STAR in U.S. and ErP regulation in Europe require the input power should be less than 0.5W at standby mode.
Output Load:
154W for convection cooling.
Peak Load Duration:
Peak 220W can last for 5 sec.
Isolation Grade:Primary ←→ Ground : 1MOPP (1500Vac)
Primary ←→ Secondary : 2MOPP (4000Vac)
Secondary ←→ Ground		 : 1MOPP (1500Vac)
Leakage Current:
Earth leakage current < 300uA
Touch current < 100uA
EMI Grounding:If there is a metal sheet under the power supply, connect the EMI ground to that metal sheet.
Model Selection:
Most of power supplies will create audible burst sound at light load, if the application wants to meet input power < 0.5W at standby mode.
SNP-P15x-S is for ITE & medical applications which require standby mode.
