Product Description
The SITAS 4AM6142-8JD40-0FA0 is a 1600VA single-phase control transformer with the widest primary tap range in the 4AM6142 series — six taps from 415V down to 215V — and dual 115V secondaries configurable for 230V at 6.96A or 115V at 13.91A. One model covers nearly any global mains voltage, simplifying inventory for international machine builders and panel shops.
Electrical Performance
Rated at 1,600VA continuous with a short-time power rating of 7,300VA (S6 duty). The laminated EI core achieves approximately 96 percent efficiency. Six primary taps handle a wide range of international grid voltages without requiring separate transformer models. Dual secondaries enable both 230V and 115V control circuit standards.
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
Ideal for international machine builders exporting control panels to countries with different mains voltages — from 215V to 415V. The dual secondary supports both 230V (European/Asian) and 115V (North American) control standards from a single transformer model at 1600VA.
