These encapsulated, PC-mountable linear power modules feature 23 single
output, 14 dual output and 13 triple output models for a wide variety of printed
circuit board applications. The 5V output of all models have overvoltage
crowbar protection as a standard feature. For maximum safety, all power
transformers are split bobbin wound, rather than layer wound, to give total
isolation with low coupling capacitance between primary and secondary.
Conservative design and rating of these modules results in reliable operation
and long life. Standard input voltage is 115VAC; other optional inputs are 220
and 240VAC. Most models are available in standard and alternate pin
configurations for second sourcing applications. This series includes 5 sub-
miniature modules for lower power applications where minimum circuit board
space is available.
