GE DS200NATOG1ABB Voltage Feedback Scaling Board

Product Details:

The GE DS200NATOG1ABB is a Voltage Feedback Scaling Board developed for GE’s LCI Innovation Series, designed to operate on VME platforms. Its core function is critical for SCR (Silicon-Controlled Rectifier) bridge systems: it reduces both DC and AC voltages from the bridge, ensuring accurate acquisition of feedback voltages—essential for maintaining stable control of the bridge’s operation.

Physically, the board features five identical series-connected resistor strings. Among these, one string includes an extra component dedicated to handling the negative and positive DC bus voltages, while the remaining strings correspond to each of the three AC phases. These resistor strings serve as the board’s input channels. Notably, while the input configuration follows a consistent design, the board’s output channels exhibit specific variances, tailored to meet the feedback signal requirements of the broader LCI system and VME platform integration.
