Compact 480V Industrial Power Where Big Generators Can’t Go

The Makinex 23kW 480V Portable Generator is engineered for contractors and tradesmen who need true high-voltage three-phase power without the size, weight, and logistics of towable or skid-mounted generators.

At less than one-third the size and weight of comparable 480V generators, this unit fits in trucks and equipment trailers, passes through standard doorways, and can be positioned directly where power is required β€” eliminating long cable runs, voltage drop, and jobsite hazards.

The generator features a permanent-magnet brushless alternator with totally independent circuits for 480V three-phase power and 110V auxiliary single-phase output. This guarantees clean, stable 480V power that is completely unaffected by auxiliary load during simultaneous operation.

Advanced alternator technology delivers up to 15% more usable power than conventional copper-wound designs while reducing electronic complexity, wear, and long-term maintenance.

Powered by a Briggs & Stratton VANGUARDβ„’ V-Twin OHV horizontal engine, the 23kW offers excellent fuel efficiency, low vibration, and reliable performance in demanding industrial environments.

Serious 480V power β€” without the bulk.
