Each output can provide up to max load separately when the power supply starts up. To exceed the max. output power continuously is not allowed.
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 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 loadand nominal line.
Efficiency is measured at rated load and nominal line.
+12VB is floating.
Model Selection:
SNP-Z20x is for ITE application.
SNP-Z207-M and SNP-Z209-M are for medical application.
