DS200NATOG2A GE LS2100, Voltage Feedback Board

Description:

The DS200NATOG2A NATO board, a product of General Electric, is a Voltage Feedback Scaling Board belonging to the second group variation. Its primary function is to attenuate AC and DC voltages on an SCR bridge, ensuring that the bridge voltage feedbacks are accurately derived. This model, designated as a G2 unit, replaces two wire jumpers with two bottom resistors, resulting in four resistors per string.

The outputs of the board are routed through five strings connected to a twenty-pin ribbon header. To prevent excessive output voltages in case the ribbon circuit is interrupted while input voltage is present, several metal oxide varistors (MOVs) are included. The burden resistors required for operation are located on the attached gate distribution status board, not on the NATO board itself.

For the DS200NATOG2A Voltage Feedback Sensing Board Model, the attenuator voltages are set using stab connectors and wire jumpers specific to the G2 variation of the NATO. It features multiple VLG and VLL inputs, with one VLL input at 2200 and a corresponding VLG input at 1270.17. These inputs result in a VLG output of 1.905. With these specific inputs, the configuration includes several wire jumpers, two resistors, and an input stab connector designated as JxA.
