OTHERS
CASE SIZE/WEIGHT
57.9X12.7X36.8mm [2.28X0.5X1.45 inches] (WXHXD) / 75g max
COOLING METHOD Conduction cooling (e.g. heat radiation from the aluminum base plate to the attached heat sink)
*1 At rated input(DC48V), rated load, and aluminum base plate temperature 25C.
*2 Ripple and ripple noise is measured by using measuring board with recommended capacitor Co & the film capacitor 0.1mF.
*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 Rated current is increased adjusting output voltage to lower than rated output voltage. Refer to the manual.
