Product Description
The SITAS 4AM6442-8JD40-0FA0 is the flagship of the SITAS transformer line — 2,000VA with the widest primary tap range (six taps from 415V to 215V) and dual 115V secondaries configurable for 230V at 8.70A or 115V at 17.39A. One model covers nearly any global mains voltage at the highest available SITAS power rating.
Electrical Performance
Rated at 2,000VA continuous with a class-leading short-time power rating of 9,700VA (S6 duty) — nearly 5x headroom. The EI 174/102 laminated core achieves approximately 96 percent efficiency. Six primary taps handle a wide range of international grid voltages. Dual secondaries support both 230V and 115V control circuit standards from a single transformer.
Mechanical Design
Substantial 158x176x164mm 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 25 kg.
Application
The ultimate choice for international machine builders exporting large control panels worldwide — one transformer covers 215V to 415V mains and both 230V/115V control standards at the highest SITAS power. Ideal for flagship automation systems, large packaging lines, and multi-cell material handling installations.
