Product InformationStore Part Number: PST-3000-12


Replaces: Samlex SA-3000K-112

The PST-3000-12 converts 12 Volts DC to 3000 Watts of pure sine-wave AC power at 120 Volts, 60 Hz.

Samlex's high frequency switch-mode design provides clean and stable pure sine wave power. The 12 volt PST series inverters can withstand dc voltages of up to 16.5 volts which means that they are compatible with high voltage dc charging-such as solar charging and equalization charging.  The PST-3000-12 has a tempature controlled fan for cooling, and has the following built in protections: input low voltage, input over voltage, over temperature, over load, short circuit. 

Samlex America offers superior quality 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. 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.

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 800 watts to run but may need 2300 watts to start. Please check with the manufacturer of your equipment to obtain minimum watts for starting operation of the equipment or device.
