FAQs
The S20N11P51S64X is designed for industrial control panels requiring isolated low-voltage power with a rugged NEMA 4X enclosure. It supports indoor-outdoor installations and is built with a copper coil for reliable energy transfer. Use cases include PLC power, sensor networks, and modular machine controls where washdown and corrosion resistance are important. Ensure the cabinet design accommodates a 0.5 kVA, single-phase transformer with 240/480 V primary and 120/240 V secondary voltages.
Key specs include a 0.5 kVA rating, 60 Hz frequency, single-phase operation, primary voltages of 240 V and 480 V, and secondary voltages of 120/240 V. The design uses copper windings and provides a 115 °C rise, suitable for indoor-outdoor service with a 57P4X frame. This combination supports efficient energy transfer while maintaining safe operating temperatures in compact control panels.
Yes. The S20N11P51S64X features a NEMA 4X enclosure (316 stainless steel) designed for indoor-outdoor use, including washdown environments. This enclosure provides enhanced moisture, corrosion, and ingress protection, enabling reliable operation in harsh industrial settings without frequent enclosure maintenance.
Plan for a 57P4X frame mounting with copper windings and no tap changer. Ensure adequate clearance for airflow and access to terminations, and verify compatibility with 240/480 V primary and 120/240 V secondary wiring in your panel. Utilize appropriate mounting hardware and confirm the enclosure can withstand your site’s environmental conditions to maximize uptime.
