About the DS3800NEPB
This particular DS3800NEPB printed circuit board product offering from General Electric was originally designed and manufactured for the Mark IV Turbine Control System Series, as specified in the various instructional manual materials made available to the manuals tab above for your convenience of research. The Mark IV Turbine Control System Series that this DS3800NEPB printed circuit board or PCB for short belongs to must be considered obsolete as a whole, as it exists truthfully as a legacy product series discontinued due to a manufacturer-identified full-series functional obsolescence that took place in one of the many years beyond this DS3800NEPB product's Mark IV Series' initial release. This DS3800NEPB device's greater Mark IV Turbine Control System Series is still definable as quite the highly-esteemed General Electric product series on the greater figurative GE marketplace, given its status as one of the final-developed GE Mark product series to incorporate the patented Speedtronic control system technology into a range of its different offerings.
Hardware Tips and Specifications
The GE Power Excitation Board DS3800NEPB can only operate when connected to the GE Mark IV PC Board. The board must be connected to a motor excitation board. The board features power amplifiers, a field current feedback signal, an armature current feedback signal, a calibration circuit, high voltage resistor bridges, and a heat-sink assembly. The board is installed in the power conversion module and if the module is operating, the installer is exposed to dangerous levels of electrical energy. To create a safe working environment, you must power down the module and all other equipment and then also stop the source of energy. A manufacturing site is typically equipped with 3-phase power supplies that produce the power needed to run all the devices. An engineering drawing is usually available for your use that details the 3-phase power cabling used in the site. Refer to it and locate the power source connected to drive. Remove the fuses from the source to disable the power to the drive. Examine the box in which the board was delivered for damage and place the box on a clean flat surface. Open the box and notice the board is wrapped in protective wrapper. Keep it in the wrapper for protection against static. The static can damage the components on the board and cause the board to be defective. Immediately before you handle the board or install the board, take it out of the static safe bag. Connect the DS3800NEPB board with other boards, if necessary, before you install them in the power conversion module.
This DS3800NEPB printed circuit board was originally manufactured for General Electric's Mark IV Turbine Control System Series. The Mark IV Series that this DS3800NEPB device belongs to, as mentioned before, is largely an obsolete General Electric product series, given the fact that it was discontinued due to functional obsolescence. With this being the truth, the DS3800NEPB functional product number itself can be identified as a decent supplementary source of DS3800NEPB Board hardware component and component specification information, as it codes for various DS3800NEPB Board details through a series of GE-formulated functional naming segments. For example, this DS3800NEPB functional product number begins with the dual-functional DS3800 series tag indirectly describing this DS3800NEPB PCB's normal Mark IV Series assembly version on top of its standard domestic location of original General Electric manufacture. This is followed through an instance of the NEPB functional product abbreviation, which was created to exist as a convenient functional and promotional shorthand alternative to the lengthy DS3800NEPB product number itself. This DS3800NEPB device's DS3800NEPB functional product number interestingly enough does not make use of any revision history or Mark IV Series grouping indication as is typical with similarly-labeled General Electric products.
