GFD233A103 3BHE02294R0103 Controller  

GFD233A103 (3BHE02294R0103) is an excitation system controller commonly used in the excitation control cabinet of generator sets.
Characteristics
1. Fast signal processing speed, capable of real-time adjustment of excitation current to stabilize unit voltage
2. Equipped with a comprehensive self-test, it can directly send an alarm signal when the board is abnormal
3. Strong hardware anti-interference ability, stable operation in strong electromagnetic environment of power plants
4. Rack plug-in installation, easy to disassemble and maintain on site
5. Support redundant configuration, single block failure will not directly affect the operation of the unit

parameter
1. DC 24V power supply, compatible with control cabinet standard power supply
2. Multi channel analog and pulse signal acquisition channels
3. Working temperature -20 ℃~60 ℃, long-term continuous operation inside the cabinet
4. Onboard status indicator light, convenient for quickly locating faults
5. Used in conjunction with ABB excitation complete rack
Application
1. Adjustment of excitation system for hydropower and thermal power units
2. Reactive power control of generator set
3. Replacement of spare parts for power plant excitation control cabinet
4. Synchronous generator voltage closed-loop control
5. Excitation control of industrial large-scale synchronous motors
GFD233A103 is the core control board in the excitation system, which is often used in the procurement of spare parts for power plant overhauls.
