*1 At rated input(DC48V), rated load. Ta= 25C, 2m/s.
*2 Ripple and ripple noise is measured by using measuring board. Refer to the manual.
*3 Drift is the change in DC output for an eight hour period after a half-hour warm-up at 25C, with the input voltage held constant at the rated input/output.
*4 When the input voltage is in the range of DC36-40V, output voltage is limited. Refer to the manual.
*5 Base Plate Option.
