DS3800NAIB

About the DS3800NAIB

The General Electric DS3800NAIB is a Multi-volt buffer board designed to work within the Speedtronic Mark IV system. The Mark IV was a step forward in gas and steam turbine control, using integrated chipsets built with overlapping two-out-of-three voting redundancies. This 'controlled failure' technology on critical controls and protection parameters minimized downtime caused by electronics failure and allowed the Mark IV to maximize overall run time.

As a multi-volt buffer, the DS3800NAIB functions to reduce power consumption by the use of dynamic voltage and frequency scaling. It has the following specifications:

• It is factory-drilled.

• It has five integrated circuits.

• It is marked: 6BAD5 and A-J, top edge.

• It has two connectors to communicate with other PCBs. These are located on opposite ends of DS3800NAIB. The male connector (218A4551 A-mp) is on the left and the female (218A4637P2) is on the right.

• It has two board extractors mounted top and bottom right.

• It has six potentiometers. This includes three trim potentiometers and three rotary potentiometers.

• It has one resistor network, located toward the bottom left of the board.

• It has 32 larger yellow polyester film capacitors (200V.) It also has 31 smaller yellow polyester film capacitors.

• It is built with multiple ceramic metal film resistors.

Installation instructions and maintenance schedules for the DS3800NAIB may be found in tech support publications such as manuals and data sheets. These were originally provided by General Electric.
