The SITAS 4AM6142-5MT10-0FA0 is a 1600VA single-phase control transformer stepping 690V down to 230V at 6.96A. Designed for the highest standard industrial distribution voltage — 690V — found in wind turbine nacelles, heavy mining equipment, and large-scale process industry installations.

Electrical Performance

Rated at 1,600VA continuous with a short-time power rating of 7,300VA (S6 duty). The laminated EI core achieves approximately 96 percent efficiency. Primary taps at 656/690/725V (±5 percent) handle the wide voltage swings common in wind and mining applications. Full galvanic isolation via II0 vector group.

Mechanical Design

Substantial 164x176x138mm IP00 open-frame construction for enclosure installation with screw terminals and screw mounting. Class B (130 C) insulation system, rated for 40 C ambient. Weighs approximately 28 kg.

Application

Critical for wind turbine nacelle control systems, mining draglines and shovels, and large process industry installations where 690V is the standard motor and distribution voltage. The 230V secondary powers control, safety, and monitoring circuits in these high-power environments.
