AIMS Power is proud to bring you this new 5000 Watt Pure Sine Power Inverter, designed for harsh environments, which has been completely overhauled and now boasts a dual GFCI outlet and is FCC certified. This product also includes a thermally controlled fan, allowing for increased efficiency and less noise. It will continue to put out stable, pure sine power and maintain output voltage, even as you battery bank voltage decreases. High output performance is achieved through a DSP (Digital Signal Process) drive. This inverter is ideal for running nonlinear loads (such as variable speed motors and small compressors). Pure sine power is also preferred for LaserJet printers, sensitive electronics, computer servers, microwaves, medical equipment, any with a circuit board and cordless drill battery chargers.
