The SITAS 4AM5742-5AT10-0FD0 is a 750VA IP54 enclosed control transformer stepping 400V down to 230V at 3.26A. Unlike the open-frame IP00 models, the 0FD0 variant features a fully sealed IP54 enclosure — protected against dust ingress and water splashes from any direction.

Electrical Performance

Rated at 750VA continuous (derated from 1,000VA due to enclosure thermal constraints) with the same 5,000VA S6 short-time rating as the open-frame 1,000VA models. The EI 150/90 core achieves approximately 93 percent efficiency. Primary taps at 380/400/420V. Full galvanic isolation via II0 vector group.

Mechanical Design

The IP54 sealed enclosure enables direct machine mounting outside traditional control panels — in washdown areas, dusty manufacturing floors, or outdoor-sheltered installations. Screw terminals inside the enclosure maintain IP54 integrity. Class B (130 C) insulation.

Application

Ideal for machine-mounted control power where a separate control panel is impractical — conveyor systems in dusty environments, food and beverage processing equipment subject to washdown, and outdoor pumping stations. The sealed design eliminates the need for a separate protective enclosure.
