General Description

M7049-103 is a 750W high efficiency switching regulator, that when fed from the rectified output of a 3-phase Permanent Magnet Generator (PMG), will provides a well-regulated, filtered, and protected 28VDC Output. The M7049-103 is designed for parallel current-sharing operation, allowing the user to parallel up to eight M7049-103 units and supports up to 6KW (7.2KW for 30 sec.). For typical application see Figure 1. Note: P/N M7049-103 is identical to M7049-102 but without the pre-assembled “Piggyback” I/O filter board that provides additional filtering and convenient Bus-bars terminals. The M7049-103 is intended for users who cannot accommodate the additional 16mm that the I/O filter board adds to the 42mm depth of the Module.
