Siemens 4AM5742-8DD40-0FA0 SITAS Control Transformer — 1 kVA
Siemens 4AM5742-8DD40-0FA0 SITAS 1-phase control transformer with multiple taps.
This Siemens 4AM5742-8DD40-0FA0 is a single-phase SITAS control and isolation transformer with a 1 kVA power rating. It features a versatile primary voltage range from 550V down to 208V, with specific taps for 550-525-500-480-460-440-415-400-380-230-208V. The transformer provides dual secondary windings, each at 115V, allowing for a combined secondary current of 4.35A (or 8.7A in parallel). It operates at 50-60 Hz, has a temperature rise of 40°C, insulation class B, and is IP00 rated. Connections are screw/flat-type, and mounting is via screws.
Meeting EN 61558-2-1, -2-2, and -2-4 standards, and recognized by UL/CSA, this transformer is ideal for a wide array of industrial control applications. Its multi-tap primary allows for easy adaptation to different supply voltages, while the dual secondary outputs offer flexibility in control circuit design. It's suited for machine tools, automation, and general electrical installations requiring reliable, isolated power.
