Note:
1.

For SNP-Y07E, +3.3V and +5V can provide up to peak load continuously but the maximum combination load should be less than 45W. In other models, peakload can be provided temporarily and continuous staying in more than rated load is not allowed.
2. At factory, all outputs in 60% rated load condition, each output is checked to be within the accuracy range while the main output is setting to within the specified accuracy range at rated load.
3. Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.
4. Load regulation is defined by changing ±40% of measured output load from 60% rated load at another output set to 60% rated load.
5. Ripple & noise is measured by using 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor at rated load and nominalline. For SNP-Y07B and SNP-Y076, one extra 39uF electrolytic capacitor should be added.
6. Hold up time is measured from the end of the last charging pulse to the time which the main output drop down to regulation limit at rated load and nominalline.
7. Rated load is maximum loading for flat mounting and free air convection cooling.
8. +5V output can be optional for SNP-Y077, -Y078, -Y079.
9. -12V output can be optional for SNP-Y07E.
10. Model Selection:
SNP-Y07x is for both of ITE application and for medical application.
