How to select a power adapter with the appropriate wattage?
Selection recommendations should be based on the device's rated power, leaving a safety margin (generally, it is advised that the adapter's rated power be 1.2-1.5 times the device's power). Additionally, parameters such as output voltage (V), current (A), connector polarity, and size constraints must be confirmed. Winna Technology technical support can assist with selection.
9. What certifications are required for export to different countries?
Certification requirements vary by market: North America requires UL/FCC/ETL, the EU requires CE/ERP, Germany requires GS, the UK requires UKCA, Japan requires PSE, South Korea requires KC/KCC, India requires BIS, Brazil requires INMETRO/NBR, South Africa requires SABS, Australia requires RCM/SAA, and China requires CCC. Winna Technology can assist in completing certifications for target markets.
What is the energy efficiency rating of the power adapter?
Winna power adapters meet DoE Level VI and EU ERP Tier 2 energy efficiency standards, with no-load power consumption below 0.075W (Level VI standard) and standby power consumption less than 0.1W. Some PD fast charging series support USB PD3.0 PPS protocol, achieving charging efficiency up to 98%.
11. What are the environmental requirements for using the power adapter?
The operating temperature range is generally -10°C to +40°C (industrial grade can reach -30°C to +70°C), and the storage temperature is -20°C to +60°C. Relative humidity is 5%-95% non-condensing. For outdoor use, an adapter with an IP protection rating can be selected.
