GE Mark IV DS3820PSCB Power Supply Module

The DS3820PSCB is a Power Supply Module manufactured by General Electric. It is part of the Mark IV Series used in GE Speedtronic Gas Turbine Control Systems. This module converts AC power to DC power, ensuring stable and reliable operation for the control system.

Key Features

The module is housed in a durable metal casing with strategically placed cutouts. These cutouts not only allow easy access to internal components but also enhance airflow for cooling. The housing includes mounting points for integration with other modules, such as slots, holes, and screw mounts. At the top, you’ll find a four-pin female connector, a circuit breaker, and a fuse. A toggle switch inside the housing controls the enable/disable function.

Technical Specifications

Input Voltage Range: The module accepts 100-240V AC input, depending on the application.
Efficiency: It operates efficiently, minimizing power loss during the conversion from AC to DC.
Protection: Built-in protections prevent damage from overvoltage, overcurrent, or short circuits.
Cooling: The module requires cooling to manage heat generated during power conversion. It can use passive or active cooling, such as heatsinks or fans.

System Controllers

The system controllers play a critical role in regulating functions like fuel flow and inlet guide vanes. Each controller manages one of the three independent servo valves, converting digital inputs into analog control signals. In case of failure, the system uses a two-out-of-three voting mechanism to ensure proper control by overriding erroneous signals. This approach helps maintain safe and efficient turbine operation even when one controller fails.
