Description
Product Overview
The GE DS200LPPAG1AAA is a Load Power Protection Assembly (LPPA) module designed for GE’s Speedtronic Mark VI and Mark VIe gas/steam turbine control systems. This module provides critical power distribution and protection functions, ensuring stable voltage regulation and fault isolation for the turbine control system’s I/O modules, processors, and peripheral devices. Part of the DS200 series, the DS200LPPAG1AAA enhances system reliability by safeguarding against overvoltage, short circuits, and load imbalances in demanding power generation environments.
Key Features
- Power Distribution: Routes and conditions 24V DC/125V DC power to downstream control components.
- Circuit Protection: Integrated fuses or circuit breakers for overload/short-circuit protection.
- Diagnostic Monitoring: LED indicators for power status, fault detection, and fuse health.
- Hot-Swap Design: Allows replacement without turbine shutdown, minimizing downtime.
- Compatibility: Interfaces with Mark VI/Mark VIe control modules (e.g., DS200DCFBG1A, DS200TBCAG1).
