This is the value that measured on measuring board with capacitor of 22mF at 150mm
from output terminal.
Measured by 20MHz oscilloscope or Ripple-Noise meter (Equivalent to KEISOKU-GIKEN:
RM103).
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.
