Conduction cooling (e.g. heat radiation from the aluminum base plate to the attached heat sink)
*1
At rated input(DC24V,DC48V) and rated load.
*2
Ripple and ripple noise is measured by using measuring board with recommended capacitor Co & the film capacitor 0.1mF.
Measured by 20MHz oscilloscope or Ripple-Noise meter (Equivalent to KEISOKU-GIKEN:RM101).
*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 DC18 - 20V, DC36 - 40V, output voltage adjustment range is 60 - 105% (except for 1R8/2R5).
