Functional Description
IS200PSCDG1ACB is a Power Supply / Contactor Driver board developed by GE. It is a part of EX2100 control system. The primary function of the Power Supply/Contactor Driver board is to manage control power distribution, power supply sensing, and contactor control within the exciter system. It acts as a central hub for regulating power and coordinating the operation of various components.
Features
- Power Source and Input Range: The board draws power from the DC link via stab-on terminals DCPL1 (+) and DCPL2 (-). It operates within a wide input voltage range, typically ranging from 80 to 400 V DC as nominal inputs. Additionally, transient operation up to 600 V DC is achievable during maximum dynamic discharge operation, ensuring adaptability to varying operational conditions.
- Control Power Production: One of the primary tasks of the Power Supply/Contactor Driver board is to generate control power for distribution to other control module cards within the system. It produces various voltage outputs essential for the operation of control boards, including +/- 24 V, +/-15 V, and +5 V.
- Distribution of Power: To facilitate power distribution, the board generates a 17.7 V AC square wave distributed through high-frequency transformers. This power is supplied to the gate driver and LAN Terminal Board (LTB) inputs, ensuring proper functioning of these critical components.
- Auxiliary Power Supplies:In addition to the main power supply outputs, the board features auxiliary supplies for generating isolated 70 V DC, sufficient to power up to 13 LUP (Low Voltage Under Protection) inputs. It also provides isolated SHWSHVM power for potential future applications, ensuring scalability and adaptability to evolving system requirements.
