Each output can provide up to peak load temporarily. Continuous staying in more than rated load is not allowed. 2. At factory, in 60% rated load condition, each output is checked to be within voltage accuracy. 3. Line regulation is defined by changing +-10% of input voltage from nominal line at rated load. 4. 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 oscilloscope and terminated each output with a 0.47uF capacitor at rated load and nominal line. 6. Hold up time is measured from the end of the last charging pulse to the time which the +5V output drop down to 4.75V at rated load and nominal line. 7. Efficiency is measured at rated load.
