NOTES: (1) All measurements are at nominal input, full load, and +25°C unless otherwise specified. (2) Load regulation is measured at 230Vac or 120Vac in percentage to indicate the change in output voltage as the load is varied from half load to full load (±%). (3) The exact obtainable load regulation depends upon the output cord selected and load current.
