About the DS3800NEPD1C1A
The GE Excitation Power Board DS3800NEPD1C1A features a hole in each corner through which you can insert a screw to secure the board. The board is populated with multiple capacitors. The board is populated with 2 power components. The GE Excitation Power Board DS3800NEPD1C1A is also populated with 1 amber indicator LED. The board also has 1 34-pin connector and multiple wire terminals for attaching wires and components to circuits. The board is also populated with 5 trimmer resistors.
When you plan the replacement of the The GE Excitation Power Board DS3800NEPD1C1A, it comes shipped with the trimmer resistors set to work in the last drive the board was installed in. That is, you must set the trimmer resistors to provide the best processing for the drive. The drive contains a unique set of the boards and moving components. This includes the high-voltage motor. The trimmer resistors allow the installer to configure the resistors to work as needed for the drive. Only a highly qualified installer should configure the trimmer resistors because a poorly tuned resistor can detract from the board operation. Use a calibrated testing device with proper probes attached to test the circuit. The probes must be in good condition and all insulating material cannot be worn or frayed.
The trimmer resistor is equipped with a small screw on the top edge. Use a screwdriver to turn the screw to configure the resistor. When the proper setting is found remove the screwdriver from the turning screw.
