🛡️ The GE DS2020LPPA340A Line Protection Board is a high-voltage printed circuit board (PCB) module designed by General Electric for their industrial control systems, specifically the Mark V Turbine Control and DS2020 Drive series.1
Its core function is Line Protection, acting as a safety barrier to protect the sensitive electronics of the drive from damaging electrical disturbances on the incoming AC power line.2
📋 Key Technical Specifications
| Feature | Specification/Description |
| Product Type | Line Protection Panel Module (LPPA) |
| Series/Family | GE Mark V DS2020 and Industrial Drive Control Systems |
| Primary Function | Surge and Fault Protection. It includes features like MOV transient voltage protection and blown fuse detection to protect the system from overcurrents and voltage spikes. |
| System Voltage Range | Designed for systems operating between 230 VAC and 600 VAC. (Note: The LPPB variant is used for higher voltage systems, 601–1500 VAC.) |
| Current Rating | 30 Amps (30A). This rating is often listed in the product specifications. |
| Board Assembly | It is typically mounted on standoffs and serves as a daughter card to a larger component within the drive panel. |
| Hardware | Features seven jumpers (JP1-JP7) and test points (e.g., E1, E3, E8) for diagnosing and testing circuit health. |
Part Number Breakdown
- DS2020: Indicates the product generation/family (part of the modular Mark V drive architecture).3
- LPPA: Stands for Line Protection Panel Assembly.4
- 340A: Specifies the 30 Amp rating, the 600V class, and the board’s revision level (A).5
The DS2020LPPA340A is essential for ensuring the reliability and safety of the drive system by preventing electrical faults from propagating and causing catastrophic damage to the main control hardware.
