Special Notes
  1. Ripple & Noise are measured at 20MHz of bandwidth with 0.1uF & 47uF parallel capacitor.
  2. Hold-up Time measured at 90% Vout.
  3. Fan Supply=12V/0.5A (max) for driving a fan.
  4. Please check the derating curve for more details.
  5. 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.
  6. The FAN supply is designed to serve as the source of the additive external fan for the cooling of the power supply, enabling the full load delivery and assuring the best life span of the product. Please do not use this FAN supply to drive other devices.
  7. 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.
  8. 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).
  9. At least 15mm insulation distance on the bottom of the unit should be kept and a Mylar film should be added between the unit and the system.
  10. CAUTION: Double pole, neutral fusing. Disconnect mains before servicing.
