About the DS3800NPCM1B1B
The DS3800NPCM1B1B is an analog exciter card. This product is a type of printed circuit board, or PCB. The DS3800NPCM1B1B was created as part of the MKIV or Mark IV series. Mark IV is a part of the Mark series made by General Electric. This series regulates processes for both gas and steam turbines while also protecting the turbine from damage due to operation under conditions which are unsafe.
The DS3800NPCM1B1B is a type of daughter board. A daughter board is a small board which is attached to another circuit board. Doing this expands the functionality of the other board and offers more options for operation to the user. The DS3800NPCM1B1B is a small circuit card which very few components. The most noticeable components are four (4) large resistors which are black in color. Each of these resistors has a resistance of twenty watts (20w) or 675 volts (675v). These resistors are fixed to the surface of the DS3800NPCM1B1B with metal wires and are held up on either end by plastic. Two (2) metal oxide varistors (MOVs) which are round and red in color can be found on one edge of the DS3800NPCM1B1B. These devices are labeled MOV1 and MOV2. Five (5) jumpers are located around the DS3800NPCM1B1B. These metal jumpers are labeled J1 through J5. The DS3800NPCM1B1B has several holes positioned at the corners and sides of the printed circuit board which enable the card to be connected to another component with screws. The full part number of the card, which is DS3800NPCM1B1B, is written on one edge of the device.
