Features:
- Identified as a next-generation LCI attenuator for the LS2100e static starter platform.
- Keeps the three AC-phase and two DC-bus feedback paths electrically separate.
- Uses a shared protected ribbon interface to deliver scaled bridge measurements.
DS200NATOG3A carries the Group 3 identity within the NATO voltage-feedback family, distinguishing it from earlier group populations that must not be substituted by catalog resemblance alone.
Its five-channel architecture lets the LS2100e control observe both sides of the DC bus while retaining individual feedback from each AC bridge phase.
The board occupies a high-potential measurement position, so matching the complete part number and the cabinet drawing takes priority over probing or altering an assumed range configuration.
The General Electric DS200NATOG3A Next-Generation LCI Voltage Feedback Scaling Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Placing the G3 attenuator in the static-starter path
- Platform identity: DS200NATOG3A is cataloged for the LS2100e rather than as a generic signal board.
- Measurement purpose: The board reduces SCR bridge potentials before feedback reaches low-voltage control electronics.
- Group distinction: G3 marks the next-generation LCI attenuator configuration and should remain part of the ordering identity.
- Drawing priority: Cabinet documentation should confirm the installed feedback-board group before a replacement is selected.
Separating phase and bus observations
- Phase paths: Three divider channels correspond to the three AC sides of the SCR bridge.
- Positive bus: A separate channel carries the positive DC-bus feedback.
- Negative bus: The fifth channel monitors the negative DC-bus side independently.
- Fault scope: A single abnormal value can be followed through its own channel without assuming that all bridge inputs are affected.
Following scaled signals beyond the divider board
- Common exit: The five DS200NATOG3A feedback outputs use the JV ribbon connection.
- Receiving stage: The cable continues to the associated board that supplies the feedback burden circuits.
- Protection: Metal-oxide varistors limit output voltage when the normal cable load is lost.
- Multi-channel symptom: Simultaneous loss across all readings directs attention to the shared cable route before five divider failures are assumed.
Handling a group-specific high-potential assembly
- Complete code: Preserve DS200NATOG3A in full because the G3 segment distinguishes this board group.
- No table transfer: A resistor or jumper table for G1 or G2 must not be applied to G3 without explicit manufacturer confirmation.
- Factory points: NATO-family test points are intended for factory use and not routine energized checks.
- Isolation: Remove bridge power before handling the assembly because its circuits operate at hazardous potential.
