¡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.
