OTHERS CASE SIZE/WEIGHT 61X12.7X116.8mm (WXHXD)/ 180g max
COOLING METHOD Conduction cooling (e.g. heat radiation from the aluminum base plate to the attached heat sink)
*1At rated input(DC280V) and rated load.
*2Ripple and ripple noise is measured by using measuring board with the recommended capacitor Co & the film capacitor 0.1mF.
Measured by 20MHz oscilloscope or Ripple-Noise meter (Equiva lent to KEISOKU-GIKEN:RM101).
*3Drift is the change in DC output for an eight hour period af ter a half-hour warm-up at 25C, with the input voltage held constant at the rated input/ou tput.
