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.
