GE DS200DCFBG1BNC | DC FEEDBACK POWER BOARD FOR GE SPEEDTRONIC MARK V GAS & STEAM TURBINE CONTROL SYSTEM

Description

PRODUCT OVERVIEW

GE DS200DCFBG1BNC belongs to GE DS200 series rack PCB cards, serving as an upgraded revision DC feedback power board for the classic Speedtronic Mark V turbine control platform. This board undertakes two core core tasks inside the turbine control cabinet: converting dual AC input into multi-channel stable DC working power for all logic control cards in the Mark V rack, and real-time collection, conditioning and feedback of armature voltage, excitation field current, AC bus current and other drive operating signals for the host controller to execute closed-loop speed regulation, load control and equipment safety protection calculation.The PCB integrates power conversion circuit, SCR drive circuit, field signal sampling circuit and multi-stage EMI filtering isolation circuit. Equipped with onboard DIP toggle switches for on-site calibration of feedback signal gain and zero offset parameters without modifying system upper computer programs.

Multiple hardware protection mechanisms including overvoltage, overcurrent, short-circuit and reverse power access are embedded on the board to avoid cascading damage to the whole control rack caused by power grid surge and field wiring faults. Adopting standard plug-in rack installation structure, it is fully compatible with AC2000, DC2000, FC2000, ME2000, CB2000, EX2000 drive units matched with Mark V system. Widely applied in thermal power steam turbine generator sets, combined-cycle gas turbine units, petrochemical large turbine compressor equipment for control cabinet maintenance and spare parts replacement.

FAQ

1. What core functional positioning does GE DS200DCFBG1BNC occupy in the Mark V turbine control system?DS200DCFBG1BNC is the core power conversion and feedback signal acquisition board of Mark V control rack. It supplies stable DC working power for each control module inside the cabinet, and collects real-time operating feedback data of drive equipment to support the turbine main controller to execute closed-loop regulation and safety interlock protection logic operation.
2. What two groups of AC input power sources are adopted by the hardware of DS200DCFBG1BNC?The board adopts dual independent AC input of 38VAC and 115VAC. 38VAC is used for internal control power conversion, while 115VAC is specially used to provide power output for the cabinet forced cooling fan system.
3. What maximum load current can the 24VDC main control power output of this board bear?The rated maximum output current of the +24VDC main control power bus is 10A, which can stably supply power to all internal logic boards of the whole Mark V control cabinet under rated normal operating conditions.
4. Which series of drive devices can DS200DCFBG1BNC be matched with in the Mark V system platform?This circuit board is universally applicable to six mainstream drive models under the Mark V platform: AC2000, DC2000, FC2000, ME2000, CB2000 and EX2000, which are widely equipped in global thermal power plant turbine generator units.
5. Does DS200DCFBG1BNC support on-site manual calibration of feedback signal characteristic parameters?The PCB is pre-installed with a complete set of DIP dial switches. Professional field maintenance engineers can adjust the gain value and zero offset of collected feedback signals according to the actual operating state of the unit, without modifying the system upper computer configuration programs.
6. What anti-interference isolation design is arranged between the feedback signal loop and the main power loop of the board?A 2500VDC high-withstand-voltage optical isolation structure is arranged between the feedback sampling circuit and the main power circuit, which can effectively isolate on-site power grid voltage surge and electromagnetic radiation interference, and improve the overall anti-interference performance of the turbine control system.
7. Will the pre-owned DS200DCFBG1BNC circuit boards you supply pass standardized full-performance safety testing before leaving the warehouse?All second-hand circuit boards will complete long-term power-on aging test, multi-channel voltage output accuracy calibration and feedback signal continuous sampling stability test before delivery, to guarantee long-term safe and stable operation after being put into the formal turbine control system.
8. What is the actual shipment lead time for spot stock DS200DCFBG1BNC finished products?Spot inventory is stored in our domestic warehouse, and formal shipment procedures will be fully completed within 3 working days after we receive and complete the verification of your official payment voucher.
