  • Page 13: Leading Particulars

    General description The QAS 14 and QAS 20 are AC generators, built for continuous running at sites where no electricity is available or as stand-by in cases of interruption of the mains. The generator operates at 50/60 Hz, 230/240 V in line-to-neutral mode and 400/480 V in line-to-line mode. The QAS 14 and QAS 20 generators are driven by a fluid-cooled diesel engine, manufactured by KUBOTA.
