COOLING METHOD Conduction cooling (e.g. heat radiation from the aluminum base plate to the attached heat sink)
*1 At rated input(DC280V) and rated load.
*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 Refer to the manual for input range.
