Electrolytic capacitors are usually a key component for ac-dc switching power supply. However, the shortcomings of electrolytic capacitor are large internal losses, large deviation of electrostatic capacity, high leakage current, and poor high/low temperature characteristic, which cause the low reliability and short lifespan of power products in extreme temperature environment.

Recently, Mornsun launched a new LN series of 3W ac-dc power supplies without electrolytic capacitors. This series solves the problems of poor high/low temperature characteristic and short lifespan of power products caused by the electrolytic capacitor. Mornsun’s LN03-12Bxx series of 3W ac-dc converters without electrolytic capacitor meet the standards of EMI Class B without external circuit, surge immunity meets Level 4 standard. The converters offer an input voltage range of 165- to 264Vac or 233- to 370-Vdc and an ultra-wide operating temperature range of -40 to 70 degrees C, and there is no requirement for derating at the range.
