Encapsulated EP design with an aluminum coil delivers rugged, compact reliability. The hard-wearing enclosure reduces moisture ingress and EMI, lowering field failures and service calls. This makes it ideal for outdoor control cabinets, dusty manufacturing floors, or crowded panel lanes where space is tight. Multiple voltage taps provide precise regulation as line conditions vary. With 1 at +5% FCAN, 2 at -5% FCBN, and 2 at +2.5% FCAN plus 4 at -2.5% FCBN, you can minimize voltage drop and protect sensitive loads. This translates into smoother PLC operation and longer component life in variable power environments. 1 kVA single-phase rating with 240/480 V primary and 120/240 V secondary ensures consistent control power for sensors, drives, and relays. Rated at 60 Hz and 115 °C rise, it maintains performance under peak loads while keeping thermal margins within design specs. The transformer integrates easily with standard control panels, reducing retrofit complexity. Indoor-outdoor capability via Weathershield and NEMA 3R enclosure means you can deploy this transformer across plant floors and weather-exposed enclosures without extra housings. The UL Listed certification supports meeting electrical safety standards in regulated environments. These attributes help shorten commissioning time and lower total cost of ownership. Warranty is 1 year from installation or 18 months from shipment, whichever comes first, backed by Eaton's policy. Ongoing reliability is supported by electrostatically shielded construction and quality materials.

FAQs
For best results, plan space for the 1 kVA transformer within standard control panels, ensure proper panel clearance for heat dissipation, and align mounting with the NEMA 3R enclosure requirements. Use the specified tap settings to accommodate supply variations and wire to compatible 240/480 V and 120/240 V circuits. The aluminum coil and encapsulated EP design simplify installation by reducing external shielding needs and improving EMI containment in compact layouts.
The device provides multiple taps: 1 at +5% FCAN, 2 at -5% FCBN, 2 at +2.5% FCAN, and 4 at -2.5% FCBN. This enables precise voltage regulation to keep secondary voltages within tolerance under fluctuating primary input or load conditions, improving reliability for PLCs, sensors, and drives without oversizing the installation.
Yes. It features an indoor-outdoor Weathershield and a NEMA 3R enclosure, making it appropriate for outdoor control cabinets and harsh manufacturing environments. The UL Listed certification further supports compliance with safety standards in exposed or variable conditions.
The primary certification is UL Listed, indicating compliance with recognized safety standards. The NEMA 3R enclosure design provides weather resistance for indoor-outdoor use. These attributes simplify regulatory approvals and support risk-managed procurement for industrial automation projects.
The product carries a one-year warranty from installation or eighteen months from shipment, whichever comes first, offering protection against early failures. Its encapsulated design and electrostatically shielded construction help reduce maintenance costs and downtime, contributing to a lower total cost of ownership over the equipment lifecycle.
