The transformer delivers a 400 VA rating with a 400 V to 230 V output, enabling consistent control power across automation components. This translates to improved PLC reliability, reduced risk of voltage drop, and simpler panel design for OEMs and integrators. It is well suited for control panels, relays, and field devices in machine tools and packaging lines, delivering predictable performance under typical industrial loads. The IEC-based STN design and housing support fast, straightforward installation, minimizing heat buildup and contributing to overall system efficiency in compact enclosures. Its compact footprint and 10.16 lb weight (dimensions roughly 4 in depth, 4.8 in width, 4.5 in height) reduce cabinet footprint, lower shipping costs, and ease retrofits. CSA compliance adds regulatory peace of mind for industrial environments, while Eaton’s warranty policy enhances lifecycle reliability and supplier support. Together, these factors reduce total cost of ownership and simplify procurement for panel builders and automation integrators.
