Note

  1. All parameters NOT specially mentioned at 230VAC input, rated load and 25℃ of ambient temperature.
  2. Ripple&noise are measured from peak to peak with band width limit of 20MHZ(0.1uF and 47uF/50V parallel capacitor under DC output full load,AC nominal input 25℃ ambient temperature).
  3. Installation clearances: top with 40mm, bottom with 20mm, left and right with 5mm. Increase the space to 10-15mm when the adjacent device is heat source.
  4. Derating may be needed under low input voltage. Please check the derating curve for more details.
  5. Efficiency test after 30 minutes of burn-in.
  6. The ambient temperature derating of 3.5℃/1000m for operating altitude higher than 2000m(6500ft).
