Note
- All parameters NOT specially mentioned at 230VAC input, rated load and 25℃ of ambient temperature.
- 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).
- 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.
- Derating may be needed under low input voltage. Please check the derating curve for more details.
- Efficiency test after 30 minutes of burn-in.
- The ambient temperature derating of 3.5℃/1000m for operating altitude higher than 2000m(6500ft).
