Functional Description

DS3820PSSB is a Power Supply Module developed by GE. It is a part of Mark IV control system. The module is comprised of two submodules NPSY and DPSS. These submodules work together to regulate and distribute power efficiently throughout the control system. NPSY typically functions as a power supply board, converting and conditioning incoming power to the required levels. The module acts as a distribution and protection board, ensuring that the power is correctly routed and safeguarded against overloads or faults.

Features

Modern gas turbine control systems use sophisticated electronics and control algorithms to optimize turbine performance and reduce emissions. These systems require a stable and reliable power source to function correctly. The power supply module plays a critical role in ensuring the control system receives the power it needs to operate optimally. Power supply modules used in gas turbine control systems typically have the following features:

• High Reliability: Power supply modules are designed to be highly reliable and durable, with robust components that can withstand harsh operating environments.
• Wide Input Voltage Range: The input voltage to the power supply module can vary depending on the location and application of the gas turbine. Therefore, power supply modules are designed to operate over a wide input voltage range, typically from 85VAC to 264VAC.
• Output Voltage Regulation: Power supply modules provide regulated DC power to the control system. This output voltage is typically held within a narrow tolerance to ensure the proper operation of the control system.
• Short Circuit Protection: Power supply modules are designed to protect against short circuits and overloads. They will typically shut down in the event of a fault, preventing damage to the control system.
• Thermal Protection: Power supply modules may include thermal protection to prevent damage from overheating. This protection can take the form of thermal shutdown or thermal limiting.
• Input Surge Protection: Power supply modules may include input surge protection to protect against voltage spikes and surges. This protection can prevent damage to the power supply module and the control system.
