1. The peak load can be temporarily provided up to 60W output and 8 seconds duration. The maximum
and continuous combinational load of SNP-Y04D for +3.3V & +5V is 28W.
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 nominal line.
6. Hold up time is measured from the end of the last charging pulse to the time which the main output
drops down to the regulation limit at rated load and nominal line.
