The SITAS 4AM5542-8JD40-0FA0 is an 800VA single-phase control transformer with the widest primary tap range in the 800VA class — six taps from 415V down to 215V — delivering 230V at 3.48A. One model covers most global mains voltages for international machine builders and panel shops.

Electrical Performance

Rated at 800VA continuous with a short-time power rating of 3,400VA (S6 duty). The EI 150/65 core achieves approximately 93 percent efficiency. The six-tap primary (415/400/385/245/230/215V) handles European 400V, UK 415V, and various 200-240V grids. Dual 115V secondary windings can be series or parallel connected.

Mechanical Design

Dimensions of 152x144x126mm IP00 open-frame with screw terminals and screw mounting. Class B (130 C) insulation. Weighs approximately 13.2 kg.

Application

Ideal for OEM machine builders exporting internationally — a single 800VA transformer covers control circuits from 215V to 415V input. Also suits panel shops stocking one model for multiple end-user voltage requirements.
