GE DS200DCFBG1BGB | DC FEEDBACK POWER BOARD FOR GE SPEEDTRONIC MARK V TURBINE CONTROL SYSTEM

Description

PRODUCT OVERVIEW

GE DS200DCFBG1BGB belongs to the DS200 series PCB card hardware, which is a dedicated DC feedback power board matched with GE Speedtronic Mark V gas / steam turbine control system. This board undertakes two core tasks: stable conversion of input AC power into multi-channel regulated DC power for each main control card of the Mark V rack, and real-time collection & feedback of armature voltage, field current, AC line current and other drive operating signals for the system closed-loop regulation calculation.The board integrates control power circuit, field power loop detection circuit, SCR drive circuit, signal conditioning and isolation circuit.

Equipped with DIP switch for on-site parameter calibration and signal proportional adjustment, built-in multi-level overvoltage, overcurrent and short-circuit hardware protection to avoid damage to the whole turbine control rack caused by power abnormality or signal surge. Adopts standard rack plug-in card installation method, perfectly compatible with AC2000, DC2000, FC2000, ME2000, CB2000 and EX2000 drive units of Mark V system. Widely used in thermal power steam turbine units, gas turbine power generation equipment, petrochemical turbine drive equipment and other power plant turbine control cabinet maintenance spare parts replacement work.

FAQ

1. What core functional positioning does GE DS200DCFBG1BGB undertake in the Mark V turbine control system?DS200DCFBG1BGB is the core power supply conversion and feedback signal acquisition board of Mark V control rack. It provides stable DC working power for each control module in the cabinet, and collects real-time operating feedback signals of the drive to support the turbine main controller to complete closed-loop regulation and safety protection logic operation.
2. What two groups of AC input power sources are designed for the DS200DCFBG1BGB hardware?The board adopts dual independent AC input of 38VAC and 115VAC. 38VAC is used for internal control power conversion, and 115VAC is specially used to output power for the cabinet heat dissipation fan.
3. What is the maximum load current supported by the 24VDC main control power output of this board?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 normal operating conditions.
4. Which series of drive devices can the DS200DCFBG1BGB be matched with in the Mark V system?This circuit board is universally applicable to six mainstream drive models under Mark V platform: AC2000, DC2000, FC2000, ME2000, CB2000 and EX2000, which are widely equipped in domestic and overseas power plant turbine units.
5. Does DS200DCFBG1BGB support on-site calibration of feedback signal parameters?The PCB is reserved with a group of DIP dial switches. Professional maintenance personnel can adjust the gain and zero offset of the collected feedback signals on site according to the actual operating state of the unit without modifying the system upper computer programs.
6. What isolation protection design is adopted between the feedback signal loop and the main power loop of the board?A 2500VDC high-strength optical isolation structure is arranged between the feedback sampling circuit and the main power circuit, which can effectively isolate power grid voltage surge and electromagnetic interference on site and improve the anti-interference performance of the whole control system.
7. Will the pre-owned DS200DCFBG1BGB circuit boards you supply pass standardized full-performance inspection before warehouse delivery?All second-hand circuit boards will complete long-term power-on aging test, multi-channel voltage output precision calibration and feedback signal continuous sampling stability test before leaving the warehouse to ensure safe and stable long-term operation after being put into the turbine control system.
8. What is the actual shipment lead time for spot stock DS200DCFBG1BGB 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.
