Converts 48VDC to 100 / 110 / 120 VAC selectable by DIP switch

Cotek offers superior quality microprocessor controlled Pure Sine Wave AC-DC power inverters for many different applications. 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.


  • True sine wave output (THD < 3% )
  • RS-232 interface / Remote control port
  • Input & output fully isolation
  • Thermostatically control cooling fan
  • Advanced microprocessor
  • Output voltage & frequency switch selectable
  • Input polarity reverse / under voltage / over voltage protections
  • Output short circuit / overload / over temperature protections
  • Built-in Voltage & Wattage meters & LED for power status
  • UL / e-13 / CE / FCC approved


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.
