How to Select Hawun AC-DC Power Modules
AC-DC power module selection requires careful consideration of electrical, thermal, and safety requirements. This guide provides systematic approach to selecting the optimal module.
Input voltage range is the first consideration. Hawun modules support universal AC input (85-264VAC) suitable for global applications. Verify the input range meets your application requirements.
Output power and voltage must match your load requirements. Select a module with at least 20% power margin for reliability. Output voltage accuracy and regulation are critical for sensitive loads.
Isolation requirements depend on application safety standards. Hawun modules offer 1500VDC to 4000VAC isolation. Medical applications require 2xMOPP (Means of Patient Protection) isolation.
Operating temperature significantly affects reliability. Hawun modules operate from -40°C to +85°C. Calculate thermal performance at maximum ambient temperature.
Safety certifications required vary by market and application. Verify the module has appropriate certifications (UL, CE, CB, medical) for your target markets.
