Product Description
The SITAS 4AM6442-5FT10-0FA0 is the highest-power 500V-primary transformer in the SITAS line at 2,000VA, stepping 500V down to 230V at 8.70A. Designed for 500V distribution systems in marine, offshore, and specialized heavy-industrial plants where maximum control power is required.
Electrical Performance
Rated at 2,000VA continuous with a short-time power rating of 9,700VA (S6 duty) — nearly 5x headroom. The EI 174/102 laminated core achieves approximately 96 percent efficiency. Primary taps at 475/500/525V (±5 percent). Full galvanic isolation via II0 vector group.
Mechanical Design
Substantial 158x176x164mm 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 25 kg.
Application
Common in large marine electrical systems (500V ship service), offshore platforms, and specialized industrial plants with 500V distribution. The 230V secondary powers extensive control, monitoring, and automation subsystems at the highest available SITAS power rating.
