The total output current is rated load with free air convection and max. load with 18CFM of forced air flow over the unit.
At factory, in 60% rated load condition, each output is checked to be within voltage accuracy.
Line regulation is defined by changing ±10% of input voltage from nominal line at rated load.
Load regulation is defined by changing ±40% of measured output load from 60% rated load at another output set to 60% rated load.
Ripple & noise is measured by using 15MHz bandwidth limited oscilloscope and terminated each output with a 0.47uF capacitor and a 47uF electrolytic
capacitor at rated load and nominal line.
Hold up time is measured from the end of the last charging pulse to the time which the main output drops down to low limit of main output at rated load
and nominal line.
Efficiency is measured at rated load and nominal line.
Model Selection:
SNP-X12x is for both of ITE applicationand for medical application.
