Copper windings provide high conductivity and durability, reducing I2R losses and extending transformer life in continuous-duty control circuits. Business impact: improved efficiency and lower maintenance costs for automation racks; application: machine panels and panel boards requiring steady 120 V outputs. The 60 Hz, single‑phase design aligns with standard North American power, ensuring seamless integration with existing automation equipment and motor starters; impact: reduces integration time and commissioning risk. 7.5 kVA VA rating supports multiple control loads, enabling centralized power distribution and fewer subpanels; application: packaging lines, conveyors, and small drives. NEMA 3R enclosure and Weathershield design enable indoor‑outdoor installation, decreasing installation downtime and permitting outdoor subpanels without additional weatherproofing; impact: improved uptime in fabrication floors and outdoor plant areas. The 511AG wiring connection simplifies wiring and improves terminal reliability, mitigating loose connections and future maintenance costs; application: retrofit projects and new builds with tight schedules. Stability and weight (137 lb) offer vibration resistance in standing installations, while dimensions (9.89 in L × 10.38 in W × 16 in H) support compact panel layouts; impact: easier cabinet planning and retrofit fits. This unit’s UL Listed status reinforces compliance, while compact packaging minimizes footprint in crowded control rooms and machine enclosures; long‑term ROI comes from reduced spare parts variety and faster panel builds.

FAQs
The transformer has a footprint of 9.89 in L, 10.38 in W and stands 16 in tall, weighing 137 lb, designed for stable, secure mounting in control panels. Use the 511AG wiring connection and ensure adequate clearance for airflow and service access. Plan for indoor‑outdoor placement with its NEMA 3R enclosure and Weathershield designation to maximize durability in harsh environments.
Primary voltage is 220 V with a 120 V secondary, operating at 60 Hz in a single‑phase configuration. It provides a 7.5 kVA voltage transformation capacity, copper windings for efficiency, and a copper winding design that supports reliable, long‑term service in control circuits and small automation loads.
Yes. The unit features a NEMA 3R enclosure and Weathershield for indoor‑outdoor use, plus UL Listed safety certification. This combination offers outdoor capability with weather resistance while maintaining safe operation in exposed environments such as exterior control cabinets or loading docks.
The transformer is UL Listed, providing recognized safety compliance for electrical equipment. It also uses a rugged NEMA 3R enclosure appropriate for indoor‑outdoor service, and the copper windings meet industry standards for high reliability in power conversion within control panels.
Copper windings and robust enclosure reduce loss and wear, lowering maintenance costs over time. The 7.5 kVA rating supports multiple loads in a single panel, reducing the need for additional transformers. A one‑year warranty (or 18 months from shipment) provides added protection during initial deployment and helps protect installation budgets.
