Skynet’s SNP-G20 Series is a 3″ x 5″ open frame power supply with an amazing power density of 9.4 watts per cubic inch plus active PFC. The 3” x 5” form factor has been an industry standard for more than 10 years. Initially the power density was around 2 watts per cubic inch then hovered around 3 watts per cubic inch for quite some time. Now the SNP-G20 series in 3″ x 5″ form factor is undoubtedly the current state-of-the-art. With built-in PFC

1. Standby Power Consumption 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.

2. Output Load:

  • 200W for convection cooling; 300W for forced air cooling.

3. Peak Load Duration:

  • Peak 400W can last for 5 sec.

4. Isolation Grade:

  • Primary Ground : 1MOPP (1500Vac)
  • Primary Secondary : 2MOPP (4000Vac)
  • Secondary Ground : 1MOPP (1500Vac)

5. Leakage Current:

  • Earth leakage current < 300uA
  • Touch current < 100uA

6. EMI Grounding:

  • If there is a metal sheet under the power supply, connect the EMI ground to the metal sheet.

7. 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 is for ITE application which requires standby mode.
  • SNP-G20x-A is for ITE application but without burst sound and no standby mode.
  • SNP-G20x-M is for medical application which requires standby mode.
  • SNP-G20x-MA is for medical application but without burst sound and no standby mode.
