FEATURES GENERAL DESCRIPTION
... In its default configuration, the double supply provides a regulated 15 V output and an unregulated 7.5 V output, which are isolated from the 5 V primary input supply. The double supply is capable of delivering up to 140 mA to external loads. The isolated data channels on Side 2 load the secondary i ...

Transformer types
A variety of types of electrical transformer are made for different purposes. Despite their design differences, the various types employ the same basic principle as discovered in 1831 by Michael Faraday, and share several key functional parts.
