FAQs
When installing the S20N11S16X, ensure the transformer is mounted in a location that provides adequate ventilation and spacing for heat dissipation. Utilize the NEMA 3R enclosure for indoor-outdoor exposure and follow the manufacturer's wiring guidelines to connect the 3A wiring option safely. Verify ambient conditions do not exceed the 115 °C rise rating and secure the unit to a vibration-free structure suitable for industrial environments.
The transformer provides 1.5 kVA of single-phase power with 50-60 Hz operation. Primary voltages are 240 V or 480 V, and the secondary is 120/240 V. It uses aluminum windings for efficient heat management. To verify compatibility, match these ratings to your control panel requirements, ensure the supply voltage aligns with the primary input, and confirm mounting clearance for safe wiring and service access.
Yes, the S20N11S16X is UL Listed, a recognized safety certification for electrical equipment. It features a NEMA 3R enclosure and Weathershield that supports indoor-outdoor use, enabling reliable operation in both indoor panels and exposed outdoor locations. This combination helps meet regulatory and environmental requirements for industrial automation projects.
The encapsulated design with aluminum windings and a rugged enclosure minimizes moisture ingress and dust intrusion, reducing maintenance needs. Expect low routine maintenance due to solid insulation, high-quality UL-rated construction, and corrosion-resistant materials. Routine checks should include visual inspection of connections and enclosure integrity, along with verifying voltage levels during commissioning and periodic testing of voltage regulation under load.
With a 1.5 kVA rating, 240/480 V primary and 120/240 V secondary, the S20N11S16X simplifies power distribution in automation systems, reducing wiring complexity and potential voltage drops. Its aluminum windings and efficient design support lower heat generation, contributing to energy efficiency goals and improved uptime for prioritized control panels, drives, and PLC-powered equipment.
