The DS200SDCIG1A is an SDCI DC power supply and instrument panel for DC2000 drive systems.

Each fuse on the board is equipped with an LED indicator to provide a reminder when the fuse is blown, which improves troubleshooting and board availability.

The DS200SDCIG1A provides multiple circuits for monitoring and instrumenting a range of AC power and DC motor signals, including armature current and voltage, field current and voltage, voltage amplitude, and phase sequence.

This allows the system to monitor a variety of important electrical parameters in real time to ensure stable operation of the drive system.

Check the LED indicators on the board to confirm which fuse has blown. The faulty fuse can be quickly located based on the on and off status of the indicator.

When performing an inspection, first open the cabinet where the board is installed to check if there are any illuminated indicators.

Because high voltage may be present on the board, do not directly touch the board or surrounding components during operation.

Always disconnect the drive power before performing any inspection and ensure that all power has been cut off.

Open the cabinet and check to ensure that the power is completely cut off. To avoid damage, you may need to wait for the board to discharge itself.

If you find that the fuse is blown, you can further check whether there is a wiring fault or short circuit in the circuit, depending on the location of the blown fuse.

If the board itself is faulty, you may need to replace it with a new one.When removing and inspecting the board, do not touch the board's panel, connecting wires, or plastic retaining clips.

When removing the connecting wires, be careful not to pull on the ribbon cable. The correct method is to hold both ends of the connector at the same time and gently separate them.
