Description
Product Overview
The GE IS200BPPBH2CAA is a critical Power Supply Module from the General Electric (GE) Mark VI gas/steam turbine control system, part of the renowned Speedtronic™ series. This specific module, the BPPB model, is designed to convert incoming plant AC or DC power into the clean, regulated, and isolated DC voltages required to power other modules within a Mark VI control cabinet, such as processor boards, I/O modules, and communication cards. Its primary function is to serve as the reliable and robust «heart» of the cabinet’s power distribution, ensuring that all sensitive electronic control components receive stable power, which is fundamental to the turbine’s safe, stable, and precise operation. The suffix
H2CAAindicates the specific hardware revision, input voltage range, output power rating, and possibly certification details.The value of the GE IS200BPPBH2CAA lies in its high reliability, built-in diagnostics, and modular hot-swap design, all essential for maximizing turbine availability. In critical turbine applications, a power supply failure can lead to an immediate unit trip. This module is engineered for continuous, fault-tolerant operation, often used in N+1 redundant configurations where multiple power supplies share the load. If one unit fails, the remaining units instantly assume the full load without interruption, preventing a shutdown. The module incorporates comprehensive self-monitoring for conditions like input loss, over/under voltage, over-temperature, and fan failure, communicating its health status to the Mark VI controller. For maintenance teams, the BPPBH2CAA is a key Field Replaceable Unit (FRU) whose health is continuously monitored, and which can be replaced online (hot-swapped) to maintain 24/7 turbine operation, directly contributing to plant reliability and reduced forced outage rates.

Key Features and Advantages
GE IS200BPPBH2CAA is distinguished by its fault-tolerant architecture and high availability design. Its core advantage is enabling true N+1 redundant, hot-swappable power systems. In a typical Mark VI cabinet, two or more BPPB modules operate in parallel, automatically load-sharing. The failure of any single module is completely transparent to the control system—the remaining module(s) seamlessly pick up the full load, ensuring zero interruption to turbine control. This design is critical for meeting the high availability requirements of power generation assets.
Intelligent monitoring and proactive maintenance capabilities are integral to its value. The power supply is not a «dumb» component; it is an intelligent node on the control network. It continuously monitors its own health and performance, reporting status and any faults (like fan failure, over-temperature, or loss of input) directly to the Mark VI controller. This allows plant personnel to receive early warnings of a degrading power supply, enabling a planned replacement during a scheduled outage rather than reacting to an unplanned failure. The clear front-panel LED indicators (Power OK, Load Share, Fault) provide instant visual status.
Robust construction and seamless integration within the Mark VI ecosystem are key benefits. Built to industrial standards, it withstands the electrical and environmental conditions of a turbine control cabinet. Its modular, hot-swap design dramatically reduces Mean Time To Repair (MTTR). As a genuine GE Mark VI component, it guarantees compatibility, performance, and cooling within the designed enclosure. For system engineers and maintenance technicians, the IS200BPPBH2CAA provides a dependable, manageable, and serviceable power foundation that maximizes the uptime of the entire turbine control system, protecting the significant revenue stream dependent on turbine operation.
Application Areas
The GE IS200BPPBH2CAA power supply module is deployed in every GE Mark VI turbine control cabinet for gas turbines and steam turbines across the power generation and mechanical drive sectors.
Its application is specific to the GE Speedtronic™ Mark VI control system, which is used on:
-
Heavy-Duty Gas Turbines (GE Frame 5, 6, 7, 9 series and advanced models).
-
Aeroderivative Gas Turbines (LM series).
-
Steam Turbines with Mark VI control.
-
Combined-Cycle Power Plants.
It is also found in marine propulsion and compressor drive applications utilizing Mark VI controls. Essentially, wherever there is a Mark VI control cabinet managing a critical turbine, one or more BPPB power supply modules are at work, providing the essential, high-availability electrical power to the control system’s «brain» and «nervous system.»
