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.
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.

¡The operative ambient temperature is different by with / without chassis cover or mounting position.
Note: In the hatched area, the specification of Ripple, Ripple Noise is different from other area.
¡Make sure the temperature at point A and point B is less than the temperatures shown in Instruction Manual 3.
¡The ambient temperature should be measured 5 to 10 cm away from the power supply so that it won’t be influenced by the heat from the
power supply. Please consult us for more details.
