The GE IS2020LVPSG3A is a Power Supply Module for the Mark VI series of GE’s Speedtronic Gas Turbine Control Systems. It is a key component that converts incoming power into the necessary low DC voltages to operate the control system’s electronics. The “w/o-335V” in the description indicates it’s a model that does not support the 335 VDC input.
Key Features and Functionality
The LVPSG3A provides stable and regulated power for the VME processor and I/O cards. Its main functions include:
- Voltage Conversion: The module takes the system’s incoming AC or DC power and converts it into the necessary low DC voltages, typically +5 V, +15 V, and -15 V, required for the operation of the control system’s electronics.
- Voltage Regulation and Filtering: It provides highly regulated and filtered power, protecting the sensitive electronic components from voltage fluctuations and electrical noise. This is essential for the reliable operation of the system.
- Fault Protection: The module has built-in fault protection features, such as overvoltage and overcurrent protection, to safeguard the downstream electronics from power-related issues.
- No 335V Input: The “w/o-335V” indicates that this specific module is not designed for the high-voltage DC input that is supported by some other Mark VI power supplies.
