        Overview Manuals Feedback Paths Range Selection JV Interface Safety & Service

        Features:

        • Attenuates three AC-phase measurements and both DC-bus measurements through separate divider strings.
        • Uses the documented Group 2 resistor-and-jumper population for multiple nominal bridge voltages.
        • Routes five scaled feedback outputs through a single protected JV ribbon interface.
        Each divider channel on DS200NATOG2A remains electrically distinct from input terminal to scaled output, allowing a single phase or bus path to be traced without treating all five readings as one circuit.

        Group 2 hardware changes the lower two positions of every divider chain from resistors to wire jumpers, and the selected stab pattern establishes the permitted nominal input level.

        The receiving board completes each feedback circuit with a burden resistor, while a local metal-oxide varistor limits the DS200NATOG2A output if the ribbon connection is interrupted.

        The General Electric DS200NATOG2A Voltage Feedback Scaling Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
        General Electric DS200NATOG2A Voltage Feedback Scaling Board Manuals,Datasheets,Link Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

        Following each bridge measurement through the board

        • AC coverage: Three independent strings accept the three phase-related bridge voltages.
        • DC coverage: Two further strings carry the positive-bus and negative-bus measurements.
        • Channel identity: The manual labels the five divider networks A through E so a suspect reading can be traced by path.
        • Receiving load: A burden resistor on the gate distribution and status board completes each scaled feedback circuit.

        Relating Group 2 hardware to the bridge level

        • Network population: Each DS200NATOG2A divider contains four series resistors and two wire-jumper positions.
        • Highest setting: The published Group 2 table includes a 4200 V nominal input arrangement.
        • Intermediate setting: A separate factory jumper pattern is documented for a 2200 V nominal bridge input.
        • Lower setting: The remaining listed configuration scales a 1200 V nominal input; the installed stabs must match the required row.

        Checking the shared scaled-output connection

        • Header: The five low-level feedback signals leave DS200NATOG2A through the 20-pin JV connector.
        • Cable route: A ribbon cable carries the outputs to the associated gate distribution and status board.
        • Open-path response: Local metal-oxide varistors limit output voltage when the ribbon load is removed.
        • System check: A multi-channel shift should be compared with the common JV cable and receiving-board connection before divider components are blamed.

        Observing the manufacturer service boundaries

        • Hazard level: Lethal potentials are present on DS200NATOG2A while the bridge and board are operating.
        • Test points: TP1 through TP5 are reserved for factory test and are not routine field measurement points.
        • Power isolation: Input power must be turned off before the board or its connected circuits are handled.
        • Repair limit: The instructions identify no end-user serviceable parts, so damaged assemblies should follow the manufacturer return process.
        Description
        General Electric DS200NATOG2A is the Group 2 version of the NATO voltage feedback scaling board used with an SCR bridge. It reduces high bridge voltages to lower feedback signals that the control electronics can measure.

        Five divider paths on DS200NATOG2A cover the three AC phases plus the positive and negative DC buses. Group 2 uses four series resistors in each path, with the two lower resistor positions replaced by wire jumpers.

        The installed jumper pattern selects one of three nominal input levels for DS200NATOG2A: 4200 V, 2200 V, or 1200 V. All digits in the board number therefore matter when the divider population is matched to the bridge.

        Scaled outputs leave DS200NATOG2A through the 20-pin JV ribbon connector and are loaded by burden resistors on the receiving gate distribution and status board. A metal-oxide varistor limits the output if that cable path is interrupted.

        Technical notes
        DS200NATOG2A uses Group 2 divider networks for 4200 V, 2200 V, or 1200 V nominal inputs; TP1–TP5 are factory test points only.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Why can DS200NATOG2A produce the wrong scale immediately after a board change?
        For DS200NATOG2A, compare the Group 2 jumper pattern with the bridge nominal voltage before adjusting any downstream calibration.
        What should be traced first when all five DS200NATOG2A feedback values shift together?
        Inspect the DS200NATOG2A JV ribbon path and the receiving-board burden circuits, because those elements are shared by the scaled outputs.
        How can one abnormal AC phase be isolated on DS200NATOG2A?
        Follow the affected DS200NATOG2A phase through its dedicated resistor string and compare it with the other two phase paths.
        If the ribbon cable opens, what protects the DS200NATOG2A output?
        A metal-oxide varistor on DS200NATOG2A limits the unloaded output; restore the JV connection before evaluating the receiving circuit.
        May TP1 through TP5 on DS200NATOG2A be used for routine field troubleshooting?
        No. TP1 through TP5 on DS200NATOG2A are factory test points, and lethal voltage may be present there during operation.
        Why must the complete DS200NATOG2A part number be checked instead of only the NATO family name?
        The DS200NATOG2A group designation identifies the divider construction, so a different NATO group can have another resistor and jumper population.
        What does a no-user-serviceable-parts notice mean for a damaged DS200NATOG2A?
        Do not attempt component-level repair on an energized DS200NATOG2A; remove power before replacing the board or inspecting its connected circuits.
