Frequently Asked Questions

How do I select the right Hawun power module for my application?

Selecting the right Hawun power module involves: 1) Determine input voltage range (AC or DC input); 2) Calculate required output voltage and current; 3) Identify isolation requirements (basic or reinforced); 4) Consider package size and mounting options; 5) Check operating temperature range; 6) Verify safety certifications required. Hawun provides detailed datasheets and our FAE team can assist with specific application recommendations.

What is the difference between AC-DC and DC-DC power modules?

AC-DC power modules convert alternating current (85-264VAC) to regulated DC output, ideal for applications powered from mains electricity. They include rectification, PFC (Power Factor Correction), and isolation. DC-DC converters transform one DC voltage to another, used for voltage step-up, step-down, or isolation in DC-powered systems. Hawun offers both types with various power levels from 1W to 500W.

Contact our FAE team for guidance on power module type selection based on your input power source.

What safety certifications do Hawun power modules have?

Hawun power modules carry comprehensive safety certifications including: UL/cUL 60950-1 and 62368-1 for IT equipment; IEC/EN 60950-1 and 62368-1 for European markets; CB certification for international acceptance; CE marking for European conformity; Medical safety IEC/EN 60601-1 for healthcare applications. Specific certifications vary by product series. Contact us for detailed certification documentation.

How do I calculate power dissipation and thermal management?

Power dissipation calculation: Pdiss = Pout × (1/η - 1), where η is efficiency. For example, a 50W module at 90% efficiency dissipates 50 × (1/0.9 - 1) = 5.6W. Thermal management considerations: Operating temperature range, airflow requirements, heatsinking for high-power modules, and PCB copper area for heat spreading. Hawun modules feature thermal shutdown protection and detailed thermal derating curves.

Contact our FAE team for thermal analysis and heatsink recommendations.
