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).
factor Io=0-35% is different.
Please contact us for details.
Please refer to the Instruction Manual 1.7.
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.

To meet the specifications. Do not operate over-loaded condition.
Parallel operation is not possible.
A circuit reducing standby power is built in this unit.
Therefore, the internal switch element is intermittent
operated, and the Ripple/Ripple Noise specification in load

Derating is required when operated with chassis and cover.
Sound noise may be generated by power supply in case of pulse
load.
When two or more units are operating it may not comply with
the IEC61000-3-2.
