We present a range of sine wave inverters that is backed by advanced dsp/mosfet based pwm technology that increases the crest factor. Unlike other inverters, our power inverters do not make any noise due to the quiet operation of the ac motor and inductive loads inside. Our dc/ac inverter has capability for fast changeover, making it compatible with computer tdr (time delay relay) and also for applications based with ac compressors. power specifications2.5 kva to 50 kvasalient featuresbetter reliability due to electronic change overauto sense intelligent control smart chargerlow total harmonic distortion
