Core Differences vs. Linear Power Supplies

Comparison Item	Switching Power Supply	Linear Power Supply
Efficiency	80%~95%	30%~60%
Size/Weight	Compact & lightweight	Bulky & heavy
Heat Generation	Low (requires small cooling)	High (requires large heat sinks)
Input Compatibility	Wide voltage adaptive	Only fits fixed input voltage

Notes
All parameters are measured at 220VAC input, rated load, and 25ºC ambient temperature unless specified.
Output voltage can be adjusted via the potentiometer on the power supply; disconnect the load before adjustment.
Ensure adequate heat dissipation and avoid blocking ventilation openings.
This power supply is a component; the final equipment must re-verify EMC compliance.
