This is the value that measured on measuring board with
capacitor of 22
m
F at 150mm from output terminal.
Measured by 20MHz oscilloscope or Ripple-Noise meter
(Equivalent to KEISOKU-GIKEN: RM103).
A circuit reducing standby power is built in this unit.
Therefore, the internal switch element is intermittent
operated, and the Ripple/Ripple Noise specifi cation in load
factor Io=0-35% is different.
Please refer to the Instruction Manual 1.7.
*
2 Drift is the change in DC output for an eight hour period after
a half-hour warm-up at 25
C
, with the input voltage held
constant at the rated input/output.
*
3 Derating is required.
*
4 When two or more units are operating it may not comply with
the IEC61000-3-2.
Please contact us for details.
*
5 Please contact us about dynamic load and input response.
*
6 Please contact us about another class.
*
To meet the specifi cations. Do not operate over-loaded condition.
*
Parallel operation is not possible.
*
Derating is required when operated with chassis and cover.
*
Sound noise may be generated by power supply in case of pulse
load.
Recommended EMI/EMC Filter
NAC-04-472
High voltage pulse noise type : NAP series
Low leakage current type : NAM series
*
The EMI/EMC Filter is recommended
to connect with several devices.
