LS03-05BY7S
3W,HIGH VOLTAGE DC-DC(AC-DC) CONVERTER
LS ----- are high efficiency green power modules with miniature
packaging provided by MORNSUN. The features of this series are: wide
input voltage, DC and AC all in one, high efficiency, high reliability, low loss,
safety isolation etc. They are widely used in industrial, office and civil
equipments, as well as applications where no special requirement for EMC
performance. It is recommended to add EMI suppression circuit or take
measure to shield when there is strict requirement for EMC performance.
PRODUCT FEATURES
1. Wide input voltage:100 ~ 400VDC(85 ~ 264VAC)
2. Over temperature protection and short circuit protection
3. High efficiency, high density
4. Low loss, green power
5. Multiple models available
6. Industrial level specifications
