Note on 400Hz operation: we have tested this power supply and found that the efficiency does not decrease at 400Hz operation, the power factor and crest factor of the incoming AC change only slightly, and the temperature rise at full power is the same as 60Hz operation.

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.
