        More Information

        Overview Manuals Supply Paths Protection Monitoring Product Applications

        Features:

        • Generates ±24 VDC, ±15 VDC, and +5 VDC rails for the drive control assembly.
        • Converts voltage and current feedback through VCO circuits across the documented 0–500 kHz range.
        • Signals a loss of regulation to the attached SDCC or LDCC through the /PSEN line.
        The DS200DCFBG1B combines low-voltage control power with field, SCR-control, and feedback-interface functions. Its role therefore extends beyond a simple single-output power module.

        Three onboard fuses protect the input and selected output sections. CR51 and CR55 indicate the associated 7 A fuse paths, while LT1 shows the state of the separate input-protection circuit.

        Twelve configurable jumpers, seven DIP switches, five testpoints, eighteen plug connectors, and nine stab connectors provide the documented setup and signal access points for the G1B board.

        Apter Power can supply official General Electric documentation and quotation support for the DS200DCFBG1B Power Supply Board.

        Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description.

        DCFB Input and Output Power Paths

        • Input source: The board accepts 38/115 VAC, with 24 VDC used in the documented EX2000 arrangement.
        • Positive auxiliary rail: The unregulated +24 VDC output is rated at 3 A.
        • Negative auxiliary rail: The unregulated -24 VDC output is rated at 1 A.
        • Analog rails: Regulated +15 VDC and -15 VDC outputs are rated at 0.8 A each.
        • Logic rail: The regulated +5 VDC output is rated at 4 A.

        Fuse and Regulation Protection

        • High-current fuses: FU2 and FU3 are documented 7 A 2AG protection devices.
        • Fuse indicators: CR51 and CR55 display the state of the associated protected paths.
        • Input protection: FU1 is a 1/2 A 2AG fuse with LT1 indication.
        • Regulation response: /PSEN rises when regulated outputs leave tolerance and resets the attached control card.
        • Load isolation: A short or overload on one protected rail can be separated from VCO feedback behavior.

        VCO and Board-Level Monitoring

        • VCO center: Voltage and current feedback conversion is nominally centered at 250 kHz.
        • Frequency span: The documented conversion range extends from 0 to 500 kHz.
        • Test access: Five onboard testpoints provide selected supply and feedback observations.
        • Switch setup: Seven DIP switches define documented circuit options.
        • Jumper setup: Twelve configurable jumpers route board-level functions on the G1B assembly.

        Supported Drive and Exciter Families

        • DC2000 and CB2000: The DCFB board supplies control power and feedback functions in documented DC drive families.
        • EX2000 excitation: The EX2000 arrangement uses the documented 24 VDC input path.
        • FC2000 and GF2000: These drive families use the board’s control-power and interface circuits.
        • ME2000 application: The same DCFB architecture supports the listed ME2000 equipment.
        • AC2000 IGBT: Selected IGBT drive arrangements apply the board within their control-power assembly.
        Description
        General Electric DS200DCFBG1B is the G1B Power Supply Board used in DC2000, CB2000, EX2000, FC2000, GF2000, ME2000, and selected AC2000 IGBT drive arrangements. Depending on the system, it receives either 38/115 VAC from a control-power transformer or 24 VDC in the documented EX2000 application.

        The DS200DCFBG1B develops unregulated +24 VDC at 3 A, -24 VDC at 1 A, regulated +15 VDC and -15 VDC rails rated at 0.8 A each, and a regulated +5 VDC rail rated at 4 A. A portion of each ±15 V rail is available for external loading.

        Additional circuits supply motor-field and shunt-field power, SCR contactor-control power, and line-current transformer interfaces. Fuse and indicator sections protect or display the state of the input and selected generated rails.

        Voltage and current feedback reach DS200DCFBG1B as VCO signals with a nominal 250 kHz center and documented 0–500 kHz range. The /PSEN output stays low while regulated power is valid and rises when regulation is lost, providing a reset signal to the connected SDCC or LDCC control card.

        Technical notes
        DS200DCFBG1B asserts /PSEN high when regulated outputs leave tolerance, initiating the documented reset path to an attached SDCC or LDCC card.

        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 DS200DCFBG1B cause a connected control card to reset even when some rails are present?
        DS200DCFBG1B drives /PSEN high when regulated outputs leave tolerance, so one failed regulated section can trigger SDCC or LDCC reset behavior.
        What should be checked when the DS200DCFBG1B +24 V or -24 V path is missing?
        For DS200DCFBG1B, check the applicable fuse, CR51 or CR55 indication, input source, load condition, and the related plug or stab connection.
        Why might DS200DCFBG1B feedback readings be wrong while its DC outputs remain normal?
        DS200DCFBG1B uses separate VCO conversion circuits for voltage and current feedback, so a feedback path can fail independently of the supply rails.
        What does an incorrect DS200DCFBG1B VCO frequency suggest?
        DS200DCFBG1B feedback conversion is centered near 250 kHz within a 0–500 kHz range; an extreme value points to input, adjustment, or conversion trouble.
        Can DS200DCFBG1B be powered identically in every supported drive family?
        No. DS200DCFBG1B normally receives 38/115 VAC, while the documented EX2000 arrangement uses 24 VDC, so the host-system input must be identified.
        Why can a new DS200DCFBG1B installation show unstable regulation?
        DS200DCFBG1B can be affected by incorrect jumper or DIP-switch settings, overloaded rails, loose stab connections, or a mismatched input-power arrangement.
        What should be verified after a DS200DCFBG1B feedback path is disturbed?
        Confirm DS200DCFBG1B connector seating, feedback polarity, VCO testpoint response, and the applicable VFBOFS adjustment before accepting the displayed value.
