CASE SIZE/WEIGHT
74.2X44.5X127mm [2.92X1.75X5.0 inches](WXHXD) / 310g max
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 with capacitor of 22mF at
150mm [5.91 inches] from output terminal.
Refer to the instruction manual 3.2.
*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 instruction manual 4.6.
*5 Refer to the instruction manual 2, 4.4
*6 Refer to the instruction manual 4.4
*7 Refer to the instruction manual 6.2
*8 "RC2" is applicable to an option not to need external power source.
