SINE-WAVE OUTPUT:

True sine-wave output with a 3% THD on batteries. This feature provides dependable and compatible power for your most critical applications. True double conversion technology with zero transfer time: This advance design provides the closest you can get to Pure constant power in the industry

HIGH FREQUENCY SWITCHING.

High frequency switching of 20-40KHz leads to high efficiency, low noise, and faster transient response. Pure sinewave output is generated with a total harmonic distortion of less than 3%. Faster switching leads to high regulation ofless than 5% from no load to fun load on a nonlinear load
