EX 400VA Transformer


Our SA POWERNET EX 400VA Transformer comprises a composite box mounted via shock absorbers onto a marine-grade steel frame, with a special internal chassis securing the internal components. The result is a phenomenally rugged electrical transformer, but with no compromise on portability - at only 17kg and 560mm wide, it'll go anywhere you need it.

A range of voltage and output options are available, as well as a Centre Tapped to Earth variant. The power transformer is supplied fully tested and ready for use.


The EX transformer is ATEX & IECEX certified so that it can be operated in Zone 1, Zone 2, Zone 21 & Zone 22 classified hazardous areas. The electrical transformer can operate in temperatures ranging from -20˚ to +40 ˚ C.

The portable, tough & durable unit is compatible with our SA Lumin Worklights so that you can illuminate your workspace with a reliable power supply unit.

Applicable to many different hazardous environments and industries, the EX 400VA Transformer also comes with a 1-year warranty.
