GE DS2020FECNRP005A with 24A NRP and 5A Shunt

GE DS2020FECNRP005A is a specialized Field Exciter Module used in the General Electric Mark V Turbine Control System and DC2000 Digital Adjustable Drive series.1

Its primary function is to provide and precisely regulate the Direct Current (DC) excitation to the field windings of a synchronous motor or generator, which is crucial for controlling the machine’s magnetic field, output voltage, and reactive power.2

⚡ Key Technical Specifications

The complex part number and features indicate its specific functional capabilities within the high-power drive system:

  • Product Series: GE Mark V (DS2020 Family) or DC2000 Drive.3
  • Functional Acronym: FECN stands for Field Exciter Control Non-reversing.4
  • Excitation Capacity: It is designed to provide excitation for up to a 24 Amp motor field.5
  • Power Supply Type: NRP (Non-Reversing Power) indicates it is compatible with Plugging field supplies, a method used for controlled, rapid deceleration.6
  • Shunt Rating: It features a 5 Amp shunt.7 A shunt is a precision resistor used in parallel with the main current path to divert a measured portion of the current. This small, proportional voltage drop is then used by the control circuitry to accurately measure the high DC current flowing to the motor’s field, enabling precise regulation.

Additional Features

Feature Detail
Control Logic Power Requires primary input of $+5 \text{ V dc}$ at $6 \text{ A}$ (for the board’s internal logic).
I/O Equipped with $12$ input channels and $12$ output channels for robust system integration.
Hardware The module includes a gating board (like the DS200FSAAG1) that contains jumpers ($\text{JP}1$ through $\text{JP}7$) for convenient configuration customization.

In summary, the DS2020FECNRP005A is the control interface that facilitates the high-power switching necessary for field excitation, while the 5A shunt allows the Mark V control system to accurately monitor the field current.
