High Performance, 5W AC/DC Converter LH05-23BxxR2 Series

High Performance, 5W AC/DC Converter LH05-23BxxR2 Series.jpg

MORNSUN has introduced its new 5W AC/DC converters LH05-23BxxR series. 

It accepts a wide 85-305VAC input and provides the tightly regulated single output of 3.3V, 5V, 9V, 12V, 15V, and 24V.

The high-performance LH-R2 series in the 305RAC family has output power ratings of 5W, 10W, 15W, and 25W. 

High efficiency, reliability, and compact-size design make it the cost-efficient power solution for size-sensitive or low-profile applications.
