12-PULSE TRANSFORMER, 3 PH, 400 HZ FOR ROV APPLICATION
This custom 35 KVA, three-phase, 400 Hz transformer is designed for reliable 12-pulse rectifier systems that require efficient power conversion and approximately 500 VDC output. Its Wye and Delta secondary arrangement helps reduce ripple and harmonic distortion, while the copper winding construction, robust core design, and oil-immersed operation provide dependable thermal performance for demanding industrial and power applications.
