Ta= 25C, 2m/s.*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 When the input voltage is in the range of DC36-40V, output voltage is limited. Refer to the manual.*5 Base Plate Option.? 520 ?CQHS-2
