Each output can last for 8 seconds without shut down.
At factory, all outputs in 60% rated load condition, each output is checked to be within voltage accuracy range while the main output is setting to within
the specified accuracy range at rated load.
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 at rated load and nominalline.
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-Z15x is for both of ITE application and medical application.
