Product Description
The SITAS 4AM6142-8ED40-0FA0 is a 1600VA single-phase control transformer with a high-range three-tap primary spanning 575/550/525V, stepping down to 230V at 6.96A. This variant extends primary coverage up to 575V, making it suitable for Canadian and heavy-industrial installations where mains voltage reaches higher levels.
Electrical Performance
Rated at 1,600VA continuous with a short-time power rating of 7,300VA (S6 duty) — over 4.5x headroom for high-inrush contactor, relay, and solenoid loads. The laminated EI core achieves approximately 96 percent efficiency. 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
Suited for machine tool control panels, HVAC systems, and industrial automation in facilities with 575V distribution — common in Canadian, South American, and heavy-industrial power networks — where 230V control power is required at 1600VA.
