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 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:
Most of power supplies will create audible burst sound at light load, if the application wants to meet input power < 0.5W at standby mode.
SNP-G30x is for ITE application which requires standby mode.
SNP-G30x-A is for ITE application but without burst sound and no standby mode.
SNP-G30x-M is for medical application which requires standby mode.
SNP-G30x-MA is for medical application but without burst sound and no standby mode.
