K78xx-500R3 DC to DC Power Module
The WHMU-3000 series represents the top of this line, offering a powerful 3000W continuous (6000W peak) output combined with battery charging. Designed for DC12V or DC24V input, it supplies modified sine wave AC power suitable for 100-120VAC or 220-240VAC loads. A key feature is the integrated 15A (12V) / 10A (24V) multi-stage battery charger with wide AC input compatibility. Includes a standard 5V 1A USB port. This high-capacity unit maintains up to 90% efficiency, relies on intelligent air cooling, and provides complete protection against voltage irregularities, overload, overheating, short circuits, and reverse polarity input.
