A higher current rating EMI/EMC filter
may be recommended in view of the
other devices that could be connected
in parallel with the power supply.
Specification is changed at
option, refer to Instruction
Manual.
This power supply is manufactured by SMD technology. The stress to P.C.B like twisting or bending causes the defect of the unit, so handle the unit with care.
*Make sure necessary tests will be carried out on your end equipment with the power supply installed in accordance with any required EMC/EMI regulations.

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.
