NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise specified. (2) Load regulation is measured at 115Vac or 230Vac in percentage to indicate the change in output voltage as the load varied from half load to full load (%). (3) The exact obtainable load regulation depends upon the output cord selected and load current. (4) Due to requests in market and advances in technology, specifications subject to change without notice. OUTPUT VOLTAGE / CURRENT RATINGS CHART 2010/6/9 SINGLE OUTPUT MODEL NO.
