LN Series AC/DC Converter for Extreme Temperature


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 range.


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.



 Blast furnace wireless temperature monitoring system

In industrial manufacturing, a temperature monitoring system is used for detecting the 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.
