FAQs
The S48G11S25N is a single-phase transformer with a 480 V primary and 120/240 V secondary. It uses 2D wiring with a tap option of 2 at -5% FCBN, and comes in a frame 182 enclosure designed for straightforward installation in standard control cabinets or switchgear assemblies.
This transformer is UL Listed and features a NEMA 3R enclosure rated for indoor-outdoor service. These fall under common safety and environmental compliance requirements for industrial equipment, supporting reliable operation in mixed environments and easing procurement with documented conformity.
Yes. With a 25 kVA rating and 60 Hz single-phase design, the transformer provides stable 120/240 V outputs ideal for PLC power supplies, control relays, and auxiliary motors within motor control centers and distributed control architectures in factories and automated lines.
Encapsulation protects windings against moisture, dust, and mechanical stresses, reducing insulation degradation and heat buildup. This translates into lower maintenance intervals, improved uptime, and more predictable performance in harsh or changing environments.
The 25 kVA rating meets typical control-panel and PLC power needs, while the rugged epoxy encapsulation and UL/NEMA-rated enclosure minimize field failures and compliance risk. The dual voltage taps add flexibility for supply variations, enabling easier integration and longer lifecycle performance with reduced total cost of ownership.
