FAQs
This transformer is DS-3 designed and totally enclosed non-ventilated, suitable for indoor or outdoor installations with Weathershield. Plan for a robust mounting surface, secure enclosure access, and proper clearance for heat dissipation. Weight is substantial at 328 lb, so include suitable lifting and anchoring during panel assembly to ensure safe, code-compliant installation.
The unit is a single-phase transformer rated at 7.5 kVA, with a 480 V primary and 120/240 V secondary, operating at 60 Hz. It features aluminum windings and a 2/4 tap arrangement (+2.5% FCAN, -2.5% FCBN) to compensate minor voltage variations during commissioning and operation.
Yes. With DS-3 design and Weathershield capability, the transformer supports indoor-outdoor installations. Ideal for control panels near loading docks or machine sheds, it retains performance in varied temperatures and exposure conditions while maintaining safe, enclosed operation.
The unit ships UL Listed, ensuring safety compliance for North American operations. It also carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first, providing protection against manufacturing defects and ensuring predictable maintenance planning.
By delivering stable 480 V to 120/240 V conversion within a compact, durable enclosure, it reduces wiring complexity and enclosure cooling needs. The 7.5 kVA rating supports scalable loads, while the low maintenance profile and rugged construction translate to higher uptime, lower replacement costs, and shorter payback periods in control systems and automation lines.
