Cotek Pure Sine Inverters/True Sine Inverters

Cotek inverters are premium quality electronic switch mode devices which take DC input from a battery or battery pack in 12 volt, 24 volt or 48 volt DC, and invert that power to 115 or 230 volt AC (alternating current) power. We carry only pure sine (true sine) units, as the modified sine power inverters are widely available. Pure sine inverters provide clean, utility grid type power (sometimes even cleaner) for proper functioning of AC devices, particularly electronic types such as computers, monitors, video and audio equipment, some motor types, and anything with a timer or microprocessor control that are sensitive to AC voltage variation. These units feature low voltage alarms and low voltage shutdown.
