GE IS220PSVOH1A （336A4940CSP15）is a servo drive power supply module for the Mark VI turbine control system. It provides precise, regulated DC power essential for operating servo valves and actuators that control fuel and steam. Designed for extreme reliability, it features comprehensive diagnostics and robust protection to ensure stable, fault-tolerant operation in critical gas and steam turbine applications.
Product Specifications
Critical Servo Actuation Power: This module delivers highly stable and regulated DC power specifically designed to drive servo valves and hydraulic actuators that precisely control fuel flow and inlet guide vanes in gas and steam turbines.
High Reliability and Redundancy: It is designed for continuous, fault-tolerant operation. The module supports N+1 redundancy and features hot-swappable capability, allowing for replacement without shutting down the turbine control system, thus ensuring maximum operational availability.
Precision Voltage Regulation: It provides tightly regulated and filtered output voltages, ensuring consistent and accurate performance of servo mechanisms, which is paramount for precise turbine control and stability.
Comprehensive Diagnostics and Monitoring: The module features extensive internal monitoring for critical parameters such as input voltage, output voltages, load current, and temperature. It communicates this status in real-time to the Mark VI controller for predictive maintenance and rapid fault identification.
Robust Environmental Protection: It is built to operate flawlessly in the harsh conditions of a power generation environment, with a design that resists shock, vibration, electromagnetic interference (EMI), and wide temperature variations.
Seamless Mark VI System Integration: As a dedicated component of the Mark VI Speedtronic system, it ensures perfect compatibility and reliable performance with the associated turbine controller (VME) and all other I/O modules.
