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.

*Providing heat sink

as option
