Key Technical Specifications
This GE DS200LRPAG1P DS200LRPAG1PR1A control card monitors 600V AC three-phase input voltage. It provides 50A overcurrent protection for drive input lines. The unit measures 24 cm in length, 17 cm in width, and 4.5 cm in height. Its total weight reaches 0.9 kg without any packaging materials.
The GE DS200LRPAG1P DS200LRPAG1PR1A includes three current transformers for phase monitoring. Additionally, it features one voltage sensing circuit for under/over voltage detection. A single 10-pin terminal block connects the line inputs. The board contains 3 CTs, 3 comparators, 1 microcontroller, 6 optocouplers, and 18 resistors.

GE DS200LRPAG1P DS200LRPAG1PR1A stores energy using one electrolytic capacitor. This capacitor provides 220 µF at 50V rating for trip memory retention. Consequently, the card maintains fault status during 30 millisecond power interruptions. Therefore, it prevents nuisance resetting after brief voltage dips.
Design and Integration
Both the GE DS200LRPAG1P and DS200LRPAG1PR1A versions share identical protection logic. These cards use four-layer PCB construction with high-voltage isolation barriers for safety. Consequently, the GE DS200LRPAG1P DS200LRPAG1PR1A operates reliably from -10°C to +55°C ambient temperature.
For installation, you need M4 screws for the four mounting holes. The card draws 100 mA typical current from an external 24V DC supply. Each CT provides 5A secondary output for accurate current sensing. We recommend using 8 AWG wire for the main line connections.
Practical Application
This line protection control card guards drive input circuits against overloads and faults. It trips the main contactor when detecting overcurrent or abnormal voltage. The GE DS200LRPAG1P DS200LRPAG1PR1A also provides a fault relay output for remote annunciation. Therefore, it protects GE drive systems from line-side electrical disturbances.
