DS200DCFBG1BLC provides control-level power to a dc drive or exciter and 115 V ac, typically used to power enclosure cooling fans.

The DCFB includes the following circuits:
Control-level power supplies (+5, ± 15, and ± 24 V dc)
Motor or generator field power circuits (except the SCR module)
Driver circuits for the armature SCR gate pulse generators
DS200DCFBG1B got circuits to instrument numerous ac line and dc motor or generator signals, including:
– Armature current and voltage
– Field current
– Ac line current
– Ac line voltage magnitude and phase sequence

To replace the DCFB board:

  1. Turn off power to the equipment, then wait for a few minutes for the DS200DCFBG1BLC’s capacitors to discharge. Test any electrical circuits before touching them to ensure power is off.
  2. Open the equipment cabinet door to access the printed wiring boards. This exposes the drive control card, which faces the front. DS200DCFBG1BLC mounted behind the drive control card, also
    facing the front.
  3. Pull the locks located on either side of the cabinet. Lift the drive control card and tilt forward and down to expose the DS200DCFBG1BLC board.
  4. To remove the DS200DCFBG1BLC board, carefully disconnect all cables as follows:
    – For a ribbon cable, place one hand on each side of the cable connector that mates with the board connector. Gently pull the cable connector with both hands.
    – For a cable with a pull tab, carefully pull the tab
  5. Plastic snaps (holders) keeps the DS200DCFBG1BLC in place. Push these holders back to release the board.
  6. On the replacement board, set all jumpers and switches in the exact position as those on the board being replaced.
    If a board revision has added or eliminated a configurable component, or re-adjustment is needed
  7. Install the new DS200DCFBG1B board, ensuring that all holders snap into position.
  8. The cables labeled with the correct connector name, as marked on the DS200DCFBG1BLC board. Reconnect all cables as labeled. Ensure the cable seating on both ends.


A printed wiring board is identified by an alphanumeric part number imprinted on it. For eg. the DS200DCFBG1B marked with part number:
The DS200DCFB portion is the base number that identifies the printed wiring board, in this case, the Power Supply Board. The r and u digits are alphabetic characters that indicate the board revision level. The r digit reflects a functional change that is not downward compatible. It is essentially a new catalog number. The u digits represent revision levels that are downward compatible.
The G# identifies a group, which is a variation of a particular board.
The DCFB board has only one group, G1. https://directturbinecontrols.com/wp-content/uploads/2020/09/Board-identification.jpg
