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:
200W for convection cooling; 300W for forced air cooling.
Peak Load Duration:
Peak 400W 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
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-G20x-U is for ITE application which requires standby mode.
SNP-G20x-UA is for ITE application but without burst sound and no standby mode.
SNP-G20x-UM is for medical application which requires standby mode.
SNP-G20x-U5 is for medical application but without burst sound and no standby mode.
