About CIB.T
The CIB.T is NPT’s thyristor-based rectifier, developed for applications that demand high direct currents with operational robustness.
The architecture includes different rectification topologies — single-phase 2-pulse and three-phase 6- or 12-pulse — allowing the solution to be adapted to the project’s electrical and construction requirements.
Local supervision tracks the rectifier’s voltage and current (VRET/IRET) in real time.
