General Purpose Rated 120W SNP-X12 Series ITE & Medical Safety Output Specifications: LINE LOAD 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. 5. Ripple & noise is measured by using 15MHz bandwidth limited...
