Our MAROC (Meidensha Accurate & Rapid Order Entry by Computer System) transformer is the sterling result of extensive trials and relentless refinement. It is made possible by our unique engineering techniques derived from our wealth of experience and tremendous R&D efforts.
The proven design, coupled with computer-aided manufacturing, makes possible quick delivery even with demanding specifications and customizations. It is unusually compact enabling a very desirable reduction in mass and space. Yet nowhere in the design is there any compromise of its outstanding performance characteristics.
