Each output can provide up to max load separately. Continuous staying in more than total output power is not allowed in free air convection. The max.
load must be with 18 CFM fan cooling.
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 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 loadand nominal line.
Efficiency is measured at rated load and nominal line.
Model Selection:
SNP-Z30x is for ITE application.
The output connector for SNP-Z30B & SNP-Z30D is shown as right-hand figure.
