  1. Ripple & Noise are measured at 20MHz of bandwidth with 0.1uF & 47uF parallel capacitor.
  2. Hold-up Time measured at 90% Vout.
  3. Please check the derating curve for more details.
  4. Strongly recommend to conduct this test with DC Voltage. If customer wishes to test with AC Voltage, please disconnect all Y-Capacitors from power supply.
  5. The size of the suggested aluminum plate is shown in the attachment. And for optimizing thermal performance, the aluminum plate must have an even and smooth surface (or coated with thermal great), and ARF240 series must be firmly mounted at the center of the aluminum plate.
  6. Please secure the power supply unit to your metal case by using the four screw holes in the corners for either Class I or Class II equipment.
  7. The ambient temperature derating of 3.5/1000m with fanless models and of 5/1000m with fan models for operating altitude higher than 2000m (6500ft).
  8. CAUTION: Double pole, neutral fusing. Disconnect mains before servicing.
