MOSA GE 90 PSX

MOSA GE90 PSX 72 KW generating set

MOSA GE90 PSX three-phase 72 KW generator set with Perkins diesel engine. The MOSA GE90 PSX generator set is equipped with electric start. The alternator of the MOSA GE90 PSX generator set is synchronous, three-phase, self-excited, self-regulated, brushless with class H insulation with AVR voltage regulator.

This MOSA is compact and convenient to maneuver and transport thanks to its compact size, with a weight of 1540 kg in addition to its practical pierceable base. The MOSA GE90 PSX genset with 230-liter tank has a fuel consumption of 14 liters/hour at 75% load for a 16-hour autonomy.
