90~264 VAC Continuous Universal Input
Skynet’s SNP-G 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-G series in 3″ x 5″ form factor is undoubtedly the current state-of-the-art. With built-in PFC
• Only 1.35 inch height
• 9.4 Watt per cubic inch
• With ITE & Medical safety
• Efficiency between 80% to 90%
• Operation from 0°C to 70°C by convection

2. Each output is checked at the factory to be within voltage accuracy with a 60% rated load condition.
3. Line regulation is defined by changing the input voltage ±10% from nominal line at rated load.
4. Load regulation is defined by changing the output load ± 40% from 60% of the rated load while another output is set to 60% of rated load.
5. Ripple & noise is measured at rated load and nominal line by using a 15MHz bandwidth limited oscilloscope with each output terminated by a 0.47 uF capacitor.
6. Hold up time is measured from the end of the last charging pulse to when the main output drops down to 95% output voltage.
7. Efficiency is measured at rated load.
