QAS 18-38 Generator Series
Powered by Yanmar Diesel

* Not on QAS 18 (single phase)

The QAS 18 - 38 range is equipped with Yanmar Diesel engines. These advanced engines include many noise reducing features to achieve low dB(a) levels, provide excellent load acceptance and stability while meeting EPA regulations. An engine coolant heater is standatd and an isochronous electronic governor is optional.

Control Panel
The Lighted easy to read control panel of the QAS allows the opwrator to monitor fuel level, engine coolant temperature* and oil pressure*. Individual ammeters monitor the amperage output on each leg, allowing the operator to easily identify load imbalances. Line to line and line to neutral voltage can be checked by totating the seven position switch on the panel. Output voltage can be fine tuned by adjusting the potentionmeteron the front panel. Arrays of the NEMA-standard convenience receptacles, protected by the individual branch circuit breakers, provided to allow quick and easy connection to the unit.
