The DS3800NPCS1A1A is a field executor snubber module. This product is a printed circuit board (PCB) which was manufactured by General Electric (GE). The DS3800NPCS1A1A is a component of the Speedtronic Mark IV turbine control series.
The DS3800NPCS1A1A contains many types of important circuit components. Four (4) large silver capacitors are featured prominently on the board. The part numbers of each capacitor are written on the devices. These capacitors are designated with the letter C. There are also four (4) medium-sized yellow capacitors which are also designated with the letter C. Each of these capacitors also contains their part number, which is 708A1. Four (4) large black resistors can be found among the large capacitors. Each of these resistors contains a wattage of 10 watts. The DS3800NPCS1A1A contains four (4) red metal oxide varistors. These varistors are designated with the letters MOV, from MOV1 to MOV4. A metal oxide varistor is a voltage-dependent resistor. These devices are passive two-terminal solid-state semiconductor devices which are used to provide protection to electrical circuits. Also located on the DS3800NPCS1A1A are four (4) silicon unilateral switches. These switches are designated with the letters SUS, from SUS1 to SUS4. Concentrated on one half of the DS3800NPCS1A1A is a collection of twenty (20) small light blue resistors. Each resistor is designated with the letter R. Four (4) small black and grey diodes are found in the center of the DS3800NPCS1A1A. Each of these diodes is designated with the letters CR. Several jumper pins with blue jumpers are also found on one of the edges of the DS3800NPCS1A1A.
