Product Overview

IS200VCRCH1BBC is current‑feedback signal‑conditioning board for Mark VIe static‑exciter. It samples and isolates field‑current feedback signals from excitation‑power‑circuit, transmits conditioned signals to main exciter‑controller for closed‑loop excitation‑current regulation. Essential component for generator‑voltage‑control loop. Surplus and refurbished tested spare feedback‑signal‑board for power‑plant excitation‑cabinet maintenance.

Application Notes

‑ Do not touch high‑voltage signal terminals while system is powered‑on. ‑ Perform signal‑loop calibration after board replacement. ‑ Typical deployment: Mark VIe exciter current‑feedback board spare‑part stocking.
