Each output can provide up to peak load temporarily. Continuous staying in more than rated load will reduce the reliability. 2. Voltage accuracy is measured with all outputs set at 60% rated load and main output is adjusted to ±1%. 3. Line Regulation measuring is done at rated loading and ±10% of input voltage changing. 4. Load Regulation measuring is done by changing the measured output loading ±40% from 60% rated load, and keep all other outputs at 60% rated load. 5. Ripple & Noise measuring is done by 15MHz band width limited oscilloscope and terminated each output with a 0.47uF ca- pacitor at rated loading. 6. Efficiency is measured at rated load. 7. Hold Up Time is measured from the end of the last full charging pulse to when the main output drop down to 95% output voltage. -James- ** This data sheet is only for models selection.
