        Overview Manuals Gate Path Cell Status Connections Protection

        Features:

        • One passive FHVA board is installed for each SCR in the LCI power converter.
        • The toroidal T1 current transformer isolates gate power between the FGPA board and one 77 mm SCR.
        • U1 returns optical blocking-voltage status while the red C STAT LED provides a local indication.
        The gate path enters through the single-turn T1 primary and leaves at P1-1 for the SCR gate, with P1-2 providing the cathode return.

        The status circuit senses equalizer current through E1 and E2; at least 50 V across a blocking SCR causes U1 to report the OFF state.

        The board is passive, requires only convection cooling, and is specified for 0 to 50 °C ambient plus a 10 °C rise inside the cabinet.

        The General Electric DS200FHVAG1A High Voltage Gate Interface Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Matching the port to the external device

        • T1 primary: Center the single-turn wire from DS200FGPA in the toroidal current-transformer window.
        • P1-1 GATE: Connect the normally white conductor to the SCR gate.
        • P1-2 CATH: Connect the normally red conductor to the SCR cathode return.
        • Gate termination: The board rectifies the transformer output and adds burden resistance for noise immunity.

        Matching the port to the external device

        • E1 EQLRES: Connect the equalizer-resistor stab to the blocking-voltage detection path.
        • E2 CATH: Return equalizer current from the status circuit to the SCR cathode.
        • U1 STATUS: Route the gray fiber-optic transmitter output to the assigned FGPA status receiver.
        • C STAT: Use the red LED only as a local indication that SCR blocking voltage is present.

        Matching the port to the external device

        • One-board assignment: Keep each FHVA matched to its single SCR and corresponding FGPA gate/status channel.
        • Gate pair: Preserve the documented red/white gate and cathode conductor orientation at P1.
        • Equalizer path: Confirm E1 and E2 return through the correct resistor and SCR cathode.
        • Optical route: Latch the U1 connector without pulling or sharply bending the fiber cable.

        Matching the port to the external device

        • High voltage: De-energize and test before touching the board because FHVA operates at SCR potential.
        • Open gate: Short P1-1 to P1-2 before energizing T1 when no SCR gate is connected.
        • Fiber lens: Fit the rubber plug whenever U1 is disconnected to prevent dust contamination.
        • Board handling: Use grounded static control, keep the board level, and retain all standoffs and lock washers.
        Description
        General Electric DS200FHVAG1A is the passive High Voltage Gate Interface Board assigned to one SCR in an LCI power bridge. It isolates gate power from the FGPA board and monitors the voltage condition of the same cell.

        A single-turn conductor from the FGPA passes through the T1 window on DS200FHVAG1A, while P1 carries the gate and cathode connections to the SCR. The toroidal transformer arrangement transfers the command without a separate local power supply.

        Equalizer-path current lets DS200FHVAG1A distinguish a blocking SCR from a conducting or failed device. The local C STAT lamp and U1 optical transmitter provide parallel local and remote indications of that blocking condition.
        Alternative Names
        DS200FHVAG1A DS200-FHVA-G1A DS200 FHVA G1A GE DS200FHVAG1A General Electric DS200FHVAG1A FHVA High Voltage Gate Interface Board DS200FHVA G1A LCI DS200FHVAG1A
        Technical notes
        On DS200FHVAG1A, a lit C STAT LED means blocking voltage is present across the associated SCR. Never use that LED as permission to touch or probe the board: the FHVA can remain several thousand volts above ground while the LCI bridge is energized.

        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 the C STAT lamp on DS200FHVAG1A stay dark while the SCR should be blocking?
        DS200FHVAG1A needs equalizer current and at least 50 V of blocking voltage to light C STAT; an open path, wrong connection, or conducting SCR removes the indication.
        If DS200FHVAG1A receives gate power but the SCR stays off, what should be traced?
        With DS200FHVAG1A de-energized, verify P1-1 gate, P1-2 cathode, and the single-turn FGPA primary through the center of T1.
        What makes R1 and R2 on DS200FHVAG1A overheat quickly?
        If T1 is energized with no SCR gate connected, DS200FHVAG1A requires P1-1 and P1-2 to be shorted; otherwise the resistors can overheat within seconds.
        How can DS200FHVAG1A show blocking locally while FGPA status remains missing?
        A lit C STAT proves local detection on DS200FHVAG1A, but remote status still depends on the U1 transmitter, connector seating, and a clean fiber path.
        When the U1 fiber is disconnected, how should DS200FHVAG1A be protected?
        Protect DS200FHVAG1A by fitting the rubber plug to U1 so dust cannot contaminate the transmitter lens during service.
        Before DS200FHVAG1A is replaced, which safety sequence is required?
        Before touching DS200FHVAG1A, switch off the bridge, verify no voltage remains, release the fiber latch, and use grounded static-control handling.
        Which identity details prevent a wrong DS200FHVAG1A replacement?
        Use the complete DS200FHVAG1A stamped number together with the GE shop-order information, LCI model, and installed board description.
