Description

EUPEC
T930S18
THYRISTOR
TNC 51
19D2
N9976

The Eupec T930S18 is a thyristor for power circuits run by marine control systems. A thyristor is a semiconductor switch that starts conducting when a pulse reaches its gate and stays on until current falls away. On board, devices of this type sit in rectifier, converter and motor control stages, where control electronics fire them to regulate the current passed to a load. The part also carries the markings TNC 51, 19D2 and N9976 beside its type number. It is supplied new without box.
