GENERAL SPECIFICATIONS
*1At rated input(DC24V,DC48V) and rated load and 25C, 2m/s.
*2Ripple and ripple noise is measured by using measuring board with ceramic capacitor 22mF. Refer to the Instruction Manual.
*3Drift 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.
*4Refer to the instruction manual for input voltage derating.
