The SITAS 4AM6142-4TJ10-0FA0 is a 1600VA single-phase control transformer converting 230V mains to 110V at 14.55A for industrial control circuits. Part of the 4AM6142 series, it steps up from the 1000VA platform with higher efficiency, greater surge capacity, and a larger core for demanding multi-contactor panels.

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 loads from contactors, relays, and solenoid valves. The laminated EI core achieves approximately 96 percent efficiency at full load. Primary taps at 218/230/242V (±5 percent) accommodate voltage fluctuations. Full galvanic isolation between primary and secondary.

Mechanical Design

Substantial 164x176x138mm IP00 open-frame construction for enclosure installation. Screw terminals on a screw-mount chassis. Class B (130 C) insulation system per IEC 60085, rated for 40 C ambient. Weighs approximately 28 kg.

Application

Typical applications include large industrial control panels, multi-motor machine tool automation, and conveyor systems where 110V control circuits are standard. The 230V primary suits European and Asian mains networks, while 1600VA supports panels with numerous contactors and relays.
