Product InformationStore Part Number: ST2500-112


Converts 12 VDC to 100 / 110 / 120 VAC

Cotek offers superior quality microprocessor controlled Pure Sine Wave AC-DC power inverters for many different applications. The ST Series are designed for Fleet, Utility, and Emergency Vehicles to run tools, lights and equipment. ST Series inverters feature a Power Saving Function and Integrated Automatic AC Transfer Switch that reacts in less than 14msec. keeping mission critical equipment online. offers PURE SINE WAVE (aka true sine wave) that provides high-end specialty users power portability for sensitive electronic equipment. The clean power delivered by a Pure Sine Wave is of the same quality and efficiency as the power provided by your utility company, which is not the case with the cheaper and more popular modified sine inverters.

We highly recommend the use of Pure Sine Wave Inverters to power Computers and related peripheral devices; i.e. printer’s, optical drives, laser copiers, and if in doubt check with the manufacturer of your equipment.

Other devices that benefit when Pure Sine Wave power is used are variable speed control motors using solid state circuitry, Audio Amplifiers, Digital Clocks and Radios, Medical Equipment, Microwaves, etc.

PLEASE NOTE: Many electrical devices require a good deal more Watts to start or energize than is required to run once started. For instance an electric motor may require only 900 watts to run but need may 2300 watts to start. Please check with the manufacturer of your equipment to obtain minimum watts for starting operation of the equipment or device. *Flat Rate shipping is for the lower 48 states only.
