NTE5744 & NTE5745
Powerblock Modules
3 Phase Bride Modules
Description:
The NTE5744 and NTE5745 powerblock modules are designed for threephase full wave rectification
and contain six diodes connected in a threephase bridge configuration. The mounting base of the
module is electrically isolated from the semiconductor elements for simple heatsink construction.
