315 VA rating and 400 V to 230 V conversion deliver precise control circuit power with a single device. Business impact: reduces the number of transformers in a panel and minimizes wiring complexity, cutting installation time and material cost. Application: ideal for control panels and machine automation where a reliable low-voltage supply is needed. The unit’s compact footprint—3.5 in length, 4.8 in width, 4.5 in height—and weight of 10.29 lb—facilitates easier panel fit and reduced enclosure space requirements, translating to faster installation and reduced cabinet size. STN design contributes to improved thermal performance and long-term reliability, minimizing maintenance intervals in demanding environments. CSA compliance and IEC-based design provide regulatory assurance, while documented data supports safe commissioning and traceability. A one-year warranty under Eaton policy 25-000 further mitigates risk, supporting lower total cost of ownership over the product lifecycle. Compatibility with standard mounting patterns and wiring practices simplifies retrofits and OEM panel builds.
