Notes: (1) Minimum voltage is guaranteed to maximum 0.2% of the rated output voltage. (2) Minimum current is guaranteed to maximum 0.4% of the rated output current. (3) At 85 ~ 132Vac or 170 ~ 265Vac, constant load. (4) From No-load to Full-load, constant input voltage. Measured at the sensing point in Remote Sense. (5) Measure with JEITA RC-9131B (1:1) probe (8) From 10% to 90% of rated output voltage, with rated resistive load. (9) From 90% to 10% of rated output voltage, with rated resistive load. (10) Time for output voltage to recover within 0.5% of its rated output for a load change from 10 to 90% of its rated output current. Voltage set point from 10% to 100% of rated output. (11) For load voltage change, equal to the unit voltage rating, constant input voltage. (12) For 6V model the ripple is measured at 2 ~ 6V output voltage and full output current.
