Electrolytic capacitor is 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 converter without electrolytic
capacitor. 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 converter 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 165～264VAC/233～370VDC and an ultra-wide
operating temperature range of -40℃~70℃, and there is no requirement for derating at
The LN series converters solve the problems of short lifespan of power products caused
by the electrolytic capacitor, and extend the average lifespan to 1.5 times than the past
converters’. The LN series AC/DC converters can be used in LED lighting, instrument and
meter, communication and industrial control, and ideal for mining, electric power industry
which has high requirements for the reliability and lifespan of the products.

inner temperature distribution and variation of blast furnace gear case. ZigBee is a wireless
communications technology, which is used for the data transmission of short distance
and low power consumption electronic devices.
Mornsun LN03-12Bxx series and LD03-10BxxR2 series can be applied in ZigBee
terminal device (temperature data receiver). It outputs stable voltage for zigbee chip and
ensures the normal operation of the temperature monitoring system.
