Notes:
- 1. All parameters are specified at normal input (48Vdc), rated load, 25°C 70% RH ambient.
- 2. Ripple & noise are measured at 20MHz by using a 12" twisted pair terminated with a 0.1µF & 47µF capacitor.
- 3. Line regulation is measured from low line to high line at rated load.
- 4. Load regulation is measured from 0% to 100% rated load.
- 5. The final equipment must be re-confirm that it still meet EMC directives. For guidance on how to perform these EMC tests, please refer to "EMI testing of component power supplies." (as available on http://www.meanwell.com)

Derating Curve
The derating curve illustrates the relationship between ambient temperature (Ta) and load percentage. It shows two curves: 'For 3.3Vo/5Vo/±5Vo' and 'Others'. The 'Natural convection' region indicates operation without forced cooling. The curve extends from -40°C to 95°C.
EMC Suggestion Circuit
To meet BS EN/EN55032 radiated Class B standards, the following external components are recommended:
- Capacitor C1: 2.2µF/100V
- Inductor L1: 12µH
The circuit diagram shows input terminals (+Vin, -Vin) connected through L1 and C1 to the DC-DC converter module (SCWN06W8 or DCWN06W8), with output terminals (+Vout, -Vout, COM) for the respective models.
