Product Overview

IS200VTCCH1CBC is thyristor trigger‑control board for GE Mark VIe static‑excitation system. Generates accurate phase‑controlled firing pulses for excitation‑rectifier SCR stack according to excitation‑control commands, realizes generator‑field‑current regulation. Key hardware for power‑plant generator excitation‑control cabinets. Surplus and refurbished tested spare trigger‑control PCB for excitation‑system maintenance.

Application Notes

‑ Strict anti‑static protection required. ‑ Verify firing‑pulse phase sequence during commissioning. ‑ Typical deployment: Mark VIe exciter thyristor trigger‑board spare‑part stocking.
