The SITAS 4AM5742-5FT10-0FA0 is a 1,000VA single-phase control transformer converting 500V mains to 230V at 4.35A. Designed for 500V distribution networks in marine, offshore, and specialized industrial environments.

Electrical Performance

Rated at 1,000VA continuous with a short-time power rating of 5,000VA (S6 duty). The EI 150/90 core achieves approximately 93 percent efficiency. Primary taps at 475/500/525V (plus or minus 5 percent). Full galvanic isolation via II0 vector group.

Mechanical Design

Substantial 152x144x132mm IP00 open-frame design with screw terminals and screw mounting. Class B (130 C) insulation, rated for 40 C ambient. Weighs approximately 15 kg.

Application

Common in marine electrical systems (500V ship service), offshore platforms, and specialized industrial plants with 500V distribution. The 230V secondary reliably powers control, monitoring, and automation subsystems in these environments.
