3BHE004573R0042
Excitation power interface: Connect the excitation regulator (such as UFC762AE101) to the thyristor rectifier bridge, and output the trigger pulse.
Signal sampling and conditioning:
High precision sampling of excitation current/voltage (± 0.1% level)
Synchronous voltage detection, phase sequence recognition, phase-locked loop (PLL)
Pulse amplification and driving: thyristor (SCR) triggers pulse amplification, isolation, and distribution.
Protection and monitoring: overcurrent, overvoltage, demagnetization, bridge arm failure, heat dissipation monitoring, fault recording.
Communication and Diagnosis: High speed communication with the main control board (UFC762AE101), online diagnosis, and LED status indication.
