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 is varied from half load to full load (unit ±%).
For the multi-output, the main output remains 50% load and other aux. output remains 20% load.
(3) The exact obtainable load regulation depends upon the output load current & cord selected. Upper data are for 6 ft. (2 m) cord AWG#18 wires.
(4) Due to requests in market and advances in technology, specifications subject to change without notice
