Product InformationStore Part Number: SA-3000K-112


Converts 12VDC to 120 VAC, ± 5%

The SA-3000K-112 industrial grade inverter is capable of driving highly reactive and capacitive loads. With a high efficiency microprocessor controlled DC-AC inverter converts 12 Volts DC (Nominal) to 3000 watts of pure sine-wave AC power at 120 Volts, 50/60 Hz (Selectable by switch). 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. printers, 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.


  • Power ON / OFF remote control available (Models S-R6-12, S-R6-24, S-R8 sold separately)
  • Isolated input and output
  • Load controlled cooling fan
  • Advanced microprocessor design
  • Output frequency 50 / 60 Hz switch selectable
  • Power saving mode to conserve energy
  • Protections: overload / short circuit, reverse polarity (fuse), over / under input voltage, over temperature
  • Tri-color indicators display input, output level & failure status
  • True sine wave output (THD < 3%)


PLEASE NOTE: Many electrical devices require a good deal more Watts to start or energize than is required 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.

Samlex S-R8 Inverter Remote
This simple switch allow the user to remotely switch on or off any SA / SK / ST series inverter made by Samlex. Allows for simple hookup with one phone jack type connector, there is no cutting and splicing necessary!
