About the IS215AEPCH1B
This IS215AEPCH1B printed circuit board, as mentioned above, was manufactured by GE Energy. GE Energy essentially exists as the alternative energy-focused shell company of larger industry giant General Electric. Because of the specialized nature of this Mark VIe Wind Turbine Control Systems Series printed circuit board, much of the information included in this individualized IS215AEPCH1B product page comes from a thorough part number breakdown of the unique IS215AEPCH1B product number. While this product is limited in terms of its availability of factory-issued manual materials, it also possesses a relatively muted general market availability, which makes a visual inspection of the product also impossible.
White not a huge amount of information concerning this IS215AEPCH1B printed circuit board specifically is available online, some fringe instructional manual materials at least identify this product's functional description. In more general Mark VIe Wind Turbine Control Systems Series documentation, this IS215AEPCH1B board is defined as a AEPC Card Module Assembly, which doesn't actually inform us much in this case. Considering similarly-named products within the same Mark VIe Wind Turbine series; it is likely that this card is more accurately named as an AE Power Card.
The tidbit of information supplied to us from original General Electric instructional manual materials is dwarfed by the amount of information afforded by a thorough breakdown of the IS215AEPCH1B individualized product number, which begins with the IS215 series tag. This series tag has dual naming functionality for the IS215AEPCH1B Card Module Assembly; detailing both this product's assembly version as well as its location of original manufacture. The IS215 tag present with this model lets us know it is a PCB with a special assembly version that was created in General Electrics' Salem, Virginia factory location. This IS215 series tag is followed in the IS215AEPCH1B product number by an inclusion of this board's AEPC functional acronym; created with the intention of being a functional and convenient shorthand for the lengthy IS215AEPCH1B product number. Following this AEPC acronym in this board's part number is the H1 series grouping tag, which, similarly to the IS215 series tag, has dual naming functionality. This H1 series grouping tag identifies the IS215AEPCH1B board as a conformally-coated printed circuit board with a group one Mark VIe Series grouping. The final trailing B digit attached to the end of the IS215AEPCH1B product number details this part's singular, B-rated functional revision.
