Description
WESTCODE
N170PH04
THYRISTOR MODULE
U9449 9303
UK
The Westcode N170PH04 is a thyristor module, a power semiconductor that conducts current once triggered by a gate signal. In a vessel’s control equipment it forms part of the power switching stage, where thyristors are used to regulate the current passed to a load. Thyristor modules of this kind appear in rectifier and converter circuits that supply control and drive equipment. The module is marked U9449 9303 and UK. It is supplied in used condition.
