WHMU-500 DC to AC Modified Sine Wave Power Inverter With Charger
The WHMU-500 series provides 500W continuous power (1000W peak) in a versatile inverter/charger unit. Choose between DC12V or DC24V input models. This unit generates a modified sine wave AC output, suitable for 100-120VAC or 220-240VAC applications. It integrates a robust multi-stage battery charger function, delivering 15A (for 12V model) or 10A (for 24V model) charging current with broad AC input compatibility (90-135VAC or 190-260VAC). A 5V 1A USB port adds convenience. Featuring 90% max efficiency, intelligent cooling, and full protection against under/over voltage, overload, heat, shorts, and reverse polarity.
