CATERPILLAR 298-3817 RECTIFIER GP

CATERPILLAR 298-3817 RECTIFIER GP is a rotating rectifier assembly designed for Caterpillar 35 series engine generator sets including 3508B, 3512B, 3512C, 3516E and G3520H gas generator units. The rectifier gp converts AC excitation current into DC power for generator rotor field winding. The rectifier gp integrates high power diodes and robust heat dissipation structure to handle continuous excitation current under heavy load. The rectifier gp stabilizes generator excitation output to maintain consistent AC voltage during load fluctuation. The rectifier gp withstands high vibration and temperature conditions inside diesel generator housings.

CATERPILLAR 298-3817 RECTIFIER GP adopts compact rotating assembly construction for direct mounting on generator rotor shaft. The excitation unit ensures reliable rectification for brushless generator excitation systems. The excitation unit reduces harmonic interference and protects excitation circuit from voltage spikes. The excitation unit is manufactured to Caterpillar OEM specifications for long service life. The excitation unit undergoes full electrical testing to guarantee stable generator voltage regulation.

CATERPILLAR 298-3817 RECTIFIER GP is widely used for marine diesel generators, land power plant and industrial standby power generation equipment. The industrial spare part can replace failed rectifier assemblies to restore generator excitation and power output rapidly. The industrial spare part matches original mechanical and electrical specifications for direct rotor installation. The industrial spare part has clear part marking for fast identification and stock management. The industrial spare part reduces generator downtime during overhaul and routine maintenance.
